Walk-In Freezer & Cold Storage Trailer Rentals in Inland Empire
KryoFridge keeps freezer and refrigerated trailers staged on the Inland Empire valley floor, from Ontario out to Redlands and south through Temecula. So a dead walk-in in Riverside or a cold overflow in a Fontana warehouse does not turn into product you throw away. Call 866-699-5802 any hour of the day, or request a quote and we will size the unit for the job.
Temporary Refrigeration for a Region Built on Cold Freight
Riverside and San Bernardino counties hold about 4.6 million people and more than 600 million square feet of industrial space. Stater Bros. runs a 2.1 million square foot distribution campus in San Bernardino. Ontario International Airport moved 618,095 tons of air cargo through September of 2025. A lot of that freight has to stay cold. When a cooler quits or the volume outruns the room you have, you need a food-safe box on your lot the same day, not a quote next week. Call 866-699-5802 and a person picks up. Or request a quote online and we will tell you the size, the power you need, and the drop time before you commit to anything.
Staged on the valley floor, not over a pass
Our Inland Empire units sit where the work is, between the I-10 and the SR-60, not up the Cajon grade or out past Banning. A loaded reefer climbing 3,777 feet of pass in July costs you an hour you do not have. Ours do not have to make that climb to reach you.
We plan around fire season, not just summer
The Line Fire burned 43,978 acres above Highland in September of 2024. The Apple Fire took at least 33,424 acres north of Beaumont and Banning in 2020. When Southern California Edison puts customers under consideration for a power shutoff, our phones light up. We hold generator capacity back for exactly those weeks.
We know what a 1980s loading dock does to a delivery
The new million square foot buildings in Fontana and Perris have yard room to spare. The older Rialto, Colton, and Mira Loma stock does not, and a ground-set trailer never lines up with a 48 inch dock on its own. We ask about your yard before the truck leaves, so the driver is not solving it in your driveway.
One number covers both counties. You are not routed to a Riverside branch and a separate San Bernardino branch. The same dispatcher handles a taqueria in Colton and a distribution floor in Moreno Valley, which is why a multi-site customer can add a second trailer with one phone call.
The Cold-Storage Name America's Biggest Brands Keep on Speed Dial
National chains do not gamble on refrigeration. A drifting set-point during dinner rush can cost a brand a day of sales and a health-code headache, so the chains that scale fast vet a cold-storage partner the same careful way they vet a protein supplier. KryoFridge has held temperature for names like McDonald's, Chick-fil-A, and Dutch Bros, and earned the repeat call.
The stories behind that trust are the kind every restaurant owner recognizes. One Friday at 6:30 in the evening, a Chick-fil-A called in with a dead walk-in and a drive-through line already wrapped around the building. We prepped a trailer, dispatched it, and had it on their pad pulling temperature 34 minutes after the phone rang. The manager's first words when the driver pulled in were, "I cannot believe you are already here." That is the bar we hold ourselves to. Another year, an overnight outage shorted a cooler on the morning of a holiday rush, and our team staged three freezer trailers to hold every pie, every protein, and every prep tray so the kitchen served the rush without missing a ticket. The reason we hear some version of that line so often is the same every time: the equipment was already nearby, already cold, and owned by the people who answered the phone. That same standard travels to every Inland Empire job, from a one-cook taqueria to a distribution floor.
Inside the Temporary Refrigeration Unit We Deliver Most
The 6x12 is the size most Inland Empire jobs land on. It holds roughly fourteen pallet positions, freezes deep, and still fits the back lots behind older commercial cores in Riverside, Upland, and San Bernardino. Ask for a quote and we will tell you plainly if a smaller box would do.
A KryoFridge trailer is a sealed, insulated, food-safe box on wheels with its own refrigeration plant on the nose. You tell us a number, we set it, and the unit holds it. That is the whole product. It swings from about 50 degrees down to roughly 10 below zero on one digital control, so the same trailer covers a dairy run in the morning and frozen product that night.
What makes it work in this region is the margin built into the plant. A condensing system sized with headroom keeps stripping heat out of the box even when the asphalt under it is baking. Riverside has hit 118 degrees. August highs average around 91. A unit that only just holds temperature on a mild day is useless here.
| Spec | What you get |
|---|---|
| Temperature range | Roughly -10°F deep-freeze up to about 50°F fresh-cold |
| Mode | Dual-purpose: freezer or refrigerator on one precise digital set-point |
| Power | A dedicated 120V, 20-amp circuit within about 100 feet, or a generator we supply |
| Food safety | NSF-approved for direct food contact, food-safe surfaces, proper drainage |
| Footprints | 6x8, 6x12, and 6x16, from a tight retail lot to distribution scale |
| Backing | Owned in-house, fully licensed and insured, with 24/7 emergency dispatch |
Each unit holds a precise digital set-point and runs on a dedicated 120V/20A circuit or a generator. The trailers are not wired for 208 to 240V building service, so we confirm your hookup before the truck rolls.
Power is the one question that decides your delivery day. The trailers run on a dedicated 120 volt, 20 amp circuit within about 100 feet, or on a generator we supply. They do not take 208 to 240 volt building service. Most Inland Empire kitchens and markets already have the right outlet, and a 30 second check on the phone keeps the driver from finding out the hard way.
Every unit is ours. We own it, service it, and drive it. Nobody is calling a partner yard in another county to see what is free while your product sits at 45 degrees.
When the 6x16 Is the Right Call
Reach for the largest box when the job is measured in pallets rather than shelves. Roughly twenty pallet positions with a heavy duty reefer plant, which is what a distribution bay, a large festival, or a relief operation actually needs. It is also the unit we lean on when the ambient temperature is brutal and the load has to stay deep frozen anyway.
The trade is footprint. A 6x16 needs room to be backed in and set straight, so it suits the newer yards in Perris, Moreno Valley, and Fontana better than a tight older lot in downtown Riverside. If your site is tight, two smaller units often beat one big one, and we will say so rather than sell you the bigger box.
Six Inland Empire Situations That Put a Trailer on a Lot
Six situations account for most of the calls we take across Riverside and San Bernardino counties. Yours is probably one of them.
🍽 Restaurants with a dead walk-in
A compressor quits on a Friday and the line still has to serve. We drop a unit, you move product across, and the kitchen runs. This is the single most common call we take from Riverside, Corona, and Rancho Cucamonga.
🛒 Grocery and market backup
A rack goes down or a remodel pulls a cold aisle offline. A trailer in the back lot carries the dairy, deli, and frozen sets until the fixed system is back, without dumping a week of inventory.
📦 Distribution and 3PL overflow
Frozen pallets show up in a building with no cold room. We stage capacity in the yard and add units as volume climbs, which is normal across the Fontana, Perris, and Moreno Valley warehouse belt.
🎪 Festivals and large events
Glen Helen Amphitheater seats 65,000 and is the largest outdoor music venue in the country. Vendor rows at that scale need real cold holding, not ice chests. Same for Old Town Temecula and downtown Riverside street events.
🚨 Food manufacturing and processing
Production lines that need a temporary cold buffer during a changeover, an inspection, or a plant expansion. The trailer becomes the staging cooler while the permanent room is out.
🏭 Emergency and disaster response
Fire, flood, and power shutoff work. Relief crews and food banks carry their own cold chain, and a staged row of trailers is that cold chain when the fixed grid is down.
What ties these together is the clock. Nobody budgets a freezer trailer into next quarter. They reach for one the hour a compressor quits, or the evening before a party when the stack of rented ice chests suddenly looks laughably undersized. Since our units sit staged around Inland Empire instead of a couple counties down the freeway, "can I get it today" is an ordinary ask here, not a stretch.
Our Trailers on Real Inland Empire-Area Jobs
Actual KryoFridge units on actual work. Retail back lots, distribution yards, event grounds, and the late-night emergencies that do not wait for morning.
What a Cold-Storage Failure Actually Costs an Operation in Inland Empire
Add it up the way an owner in Inland Empire has to. One restaurant walk-in routinely sits on a small fortune in proteins, dairy, and prepped product. Scale that to a grocery rack or a warehouse freezer bay and the exposure balloons. Now knock the power or the compressor out on a triple-digit afternoon, and that whole inventory is in jeopardy inside a few hours. Then stack on the sales you lose while the line sits dark and the wages you burn paying staff to triage what can still be saved.
Hold a pre-staged trailer up against that risk and it reads like cheap insurance, a fixed, predictable expense parked in front of a loss with no ceiling. That is exactly why the businesses that got stung once tape our number by the phone. There is never a second scramble, because the next time they dial before the product has a chance to warm. Owning every trailer ourselves means we can scale the answer to fit. A single compact box suits a corner cafe. A clustered setup covers a warehouse floor. Either turns around the same day.
Triple-Digit Heat and Why Refrigeration Quits in Riverside County
Heat is the quiet reason most of our summer calls happen. August is the warmest month in Riverside, with average highs around 91 degrees, and the city has recorded 118. East of the San Gorgonio Pass the desert side runs past 110. None of that is unusual here. What is unusual is a walk-in compressor that has never had a break since May.
Heat does two things at once, and both work against you. It raises the load on refrigeration that was already marginal, so a unit that coped in March fails in July simply because it never gets to rest. And it shortens your reaction window, because product warms faster at 105 degrees than it does at 70. Four cumulative hours above 40 degrees and most refrigerated inventory is no longer safe to serve.
That is the math behind booking ahead. Remodels, seasonal builds, and known events are easy to plan around, and Riverside freezer trailer rentals get tight in the same weeks every year. For everything else, our line stays live around the clock, because a compressor does not check the calendar before it quits.
Fire Season, Power Shutoffs, and Holding the Cold Chain Together
The Inland Empire does not lose power the way the rest of the state talks about it. California has not called a Flex Alert since 2022. What this region actually gets is wind, fire, and planned shutoffs. Santa Ana gusts funnel through the Cajon Pass and the San Gorgonio Pass at 60 to 70 miles an hour in a strong event, and the canyons can see far worse.
When that happens, Southern California Edison can put customers across Riverside and San Bernardino counties under consideration for a Public Safety Power Shutoff. In one extreme wind event the utility has flagged more than 294,000 customers for possible shutoff across six counties. Highland, Yucaipa, Redlands, Beaumont, and Banning sit in the middle of that map. So does a lot of the back country above Corona and Temecula.
The fires behind those shutoffs have names. The Old Fire burned 91,281 acres in 2003. The Line Fire took 43,978 acres above Highland in the fall of 2024. The El Dorado Fire burned 22,744 acres around Yucaipa and Oak Glen in 2020. Every one of those weeks put grocery, restaurant, and food bank inventory at risk somewhere downhill of the burn.
A trailer running on a generator does not care that the block is dark. That is the whole point of Inland Empire emergency cold storage trailer rental in fire season. We hold units and generator capacity back from late September through the winter wind months, because that is when the calls come. If you run a site in a shutoff zone, call before the wind advisory, not after.
Warehouse Overflow, Air Freight, and Cold Room Downtime
Most of the buildings in this region were built for dry goods. Over 600 million square feet of industrial space sits between Ontario and Beaumont, and only a slice of it has cold rooms. So the moment a tenant lands a food account, or an existing cold room goes down for service, the pallets have nowhere to go.
That is the most common warehouse call we take. A grocery or food service customer needs six weeks of frozen overflow while a room is rebuilt. A third party logistics tenant in Fontana picks up a frozen SKU the building was never wired for. A produce load comes off a plane at Ontario and the receiving cooler is already full. Ontario moved 618,095 tons of air cargo in the first nine months of 2025 alone, up 11 percent year over year, and UPS runs a major air operation there.
We can cluster units and bring them online in stages, which matters on a distribution floor. One 6x16 covers a bay. Three of them cover a season. Because the fleet is ours, we can phase them in as your volume climbs instead of making you commit to peak capacity in week one. Fontana industrial freezer trailer rentals and mobile cold storage freezer trailer rentals across Ontario usually start exactly this way.
One practical note from our drivers. A ground-set trailer does not meet a standard dock, and most Inland Empire dock doors have no insulation or seal because the building was never meant to hold cold. We plan the drop point around how your yard actually works, and we would rather ask three questions on the phone than send a truck twice.
Setting the Right Temperature for What You're Holding
"Cold" is not one number. Different product stays safe inside different temperature windows, which is the entire reason a precise digital set-point matters, and in the middle of a heat wave in Inland Empire, a load that slips out of its window is a load you write off. Use the chart below as the reference our customers lean on when they size a rental.
| Product | Target holding band | Trailer mode |
|---|---|---|
| Ice cream and frozen desserts | -10°F to 0°F | Deep freeze |
| Frozen proteins, seafood, prepared meals | 0°F or below | Freezer |
| Fresh meat and poultry (short hold) | 28°F to 32°F | Refrigerated |
| Dairy, deli, packaged produce | 34°F to 38°F | Refrigerated |
| Beverages, florals, catering trays | 38°F to 45°F | Refrigerated |
One figure outranks everything in that chart, and it is not listed there: 40°F. Food-safety guidance treats the band between 40°F and 140°F as the zone where bacteria thrive, and the clock on perishable product starts ticking the moment it crosses 40 on the way up. Roughly four cumulative hours above that line and most refrigerated inventory is no longer safe to serve. Picture that countdown running on a 100-degree afternoon in Inland Empire with the walk-in dark, and the urgency of a quick trailer drop stops being abstract.
Tell us the single coldest item you are holding when you call, and we dial the trailer to that. One unit carries a straight freezer load with no fuss. But when your list mixes deep-freeze desserts with fresh-cold produce for the same remodel or event, we will usually point you toward a split setup or a second box so neither side of the load has to settle for the wrong temperature.
Power and Placement on Your Inland Empire Site
Powering one of our trailers is refreshingly simple, and there are precisely two ways to do it. Either you have a dedicated 120-volt, 20-amp circuit reachable within roughly 100 feet of the parking spot, or we bring a generator. What the units will not accept is standard 208 to 240V building service, so a quick question about your outlet before dispatch heads off any surprise on delivery day.
- Dedicated outlet on hand? Most Inland Empire kitchens and markets already have the right one, so we plug straight in and the unit begins pulling the temperature down.
- Open lot or event field? A generator keeps the trailer running anywhere, whether that is an event lawn or a warehouse yard.
- Worried about a shutoff? A unit on a generator keeps your cold chain alive when a fire-season power shutoff takes the surrounding grid down.
On placement, all the unit really asks for is a fairly flat patch with enough room for the delivery truck to maneuver it in and set it straight, plus either a power source in reach or space for a generator. We lock down the exact drop point before dispatch, and our drivers know the Inland Empire layout cold, so the delivery is one clean trip instead of a guessing game on the property.
From the Field, Recent Saves Around Inland Empire
Grocery manager, San Bernardino
A frozen rack failed on a Saturday morning with the store already open. We had a 6x12 in the back lot and pulling temperature that afternoon, and the crew moved the frozen sets across on flat carts. Nothing went in the dumpster.
Event caterer, Old Town Temecula
A three day wedding weekend with no kitchen on site and a forecast in the high 90s. One trailer held all the proteins and dairy at 38 degrees for the full run, which meant the team was not driving product back to a commissary every night.
Warehouse operations lead, Fontana
A new frozen account landed before the building's cold room was built out. We staged one 6x16, then a second three weeks later as the volume climbed, and pulled them both when the permanent room came online.
From First Call to Pickup, Step by Step in Inland Empire
On a bad day, booking should be the part that does not add stress. Four steps, an upfront number, and a single person who owns the whole thing.
1 · Describe the load
Tell us whether it is freezer or fridge product, a ballpark volume, and your rough window. That is enough for us to call the right size.
2 · We finalize size, power & spot
We pair you with a unit, confirm whether you have a dedicated circuit or need a generator, and pin the exact drop point so the truck makes one trip.
3 · Delivery and cold-down
We arrive on your schedule, about 45 minutes for a true emergency, set the trailer, energize it, and let it drive down to your number.
4 · Run it, reach us anytime
It holds the set-point for your entire term while our line stays live the whole way through. Wrap up, and we swing back for the pickup.
The 41 Degree Rule Inland Empire Event Vendors Get Wrong
If you are serving food at a public event in either county, cold holding is a permit question, not just an operations question. Temporary food facilities have to provide cold-holding equipment that keeps perishable food at 45 degrees or colder. Here is the part that costs vendors money: food held at 45 degrees has to be thrown out at the end of the operating day.
Food held at 41 degrees or colder is different. It can be kept overnight, for the duration of the event, as long as it is held by mechanical refrigeration the whole time. That single line is why a reefer trailer pays for itself over a three day festival. Ice chests do not qualify, and under the state code ice and dry ice are not accepted as the only method of holding temperature on a mobile food unit either.
The paperwork side is worth knowing early. Riverside County expects a community event organizer permit at least two weeks before the event, and events are capped at 25 operating days in any 90 day window. The rules and forms come from the Riverside County Department of Environmental Health and, on the other side of the county line, San Bernardino County Environmental Health Services. We are not the permit office, but we will happily send the trailer's specifications so you can attach them to your packet.
What our trailers bring to a health-code inspection
- NSF-approved interior surfaces built for direct food contact.
- A digital controller that puts the set-point in plain view for the inspector.
- Proper drainage and a sealed, food-safe insulated box.
- Licensed and insured on every unit we put on the road.
One caveat we always state plainly: we supply the food-safe, temperature-holding hardware itself, but we are not a temperature-logging or alarm-monitoring service. If your program requires continuous written records, line that vendor up on your own.
Three Trailer Sizes, and How to Pick Yours
We stock three footprints, and together they stretch from a one-kitchen overflow all the way to distribution and disaster-scale capacity. Each one is dual-purpose by design, a single adjustable system that swings between freezer and refrigerator on a precise digital set-point, and each one lives on either a dedicated circuit or a generator.
| Trailer | Best for | Temp range |
|---|---|---|
| 6x8 | Tight lots, small kitchens, short overflow | -10°F to 50°F |
| 6x12 | Grocers, caterers, mid-size events | Deep-freeze capable |
| 6x16 | Distribution, large events, disaster | Heavy-duty reefer |
Each unit holds a precise digital set-point and runs on a dedicated 120V/20A circuit or a generator.
6x8, the compact pick for tight retail lots
Think eight or so pallet spots, and the unit to grab when square footage is the whole problem. It slips into the pinched service yards and cramped back-of-house corners that a larger box cannot even swing into. One cafe or small-market walk-in goes down, and this is almost always enough cold to cover it, plus the simplest unit to set in a small space.
6x12, the everyday pick for grocers and caterers
Call it fourteen pallet spots, deep-freeze rated, and far and away the size people ask for most. It lands right in the middle: roomy enough for a multi-day catering job or a restaurant that needs true walk-in-equivalent room while the kitchen is torn up. Roomy enough that nobody is playing Tetris with shelves, yet still small enough to set in most commercial back lots without a site survey.
6x16, the heavy hauler for distribution and disaster
Roughly twenty pallet spots paired with a heavy-duty reefer plant engineered to keep deep-freeze locked in even when the ambient air is merciless. Reach for it when a warehouse bay drops, when a large festival needs an anchor, or when a relief operation is carrying its own cold chain.
Not sure which size fits? Tell us roughly what you are storing and for how long, and we will spec it for you rather than nudging you into a bigger unit than the job calls for.
More Inland Empire Cold-Storage Rental Questions
The questions that surface once the basics are settled. Tap any topic to open it.
Freezer trailer vs. portable walk-in vs. reefer truck. Which should you rent?
The pop-up walk-in cooler. Cheap to rent and easy to set up, but it chills, it does not freeze, and it draws every watt it needs from your building while depending on a calm ambient temperature around it. The second your building loses power, your cooler loses it too.
The refrigerated box truck. Designed to haul product on the interstate, not to sit in a lot and babysit it. Parked, it idles fuel all day, broadcasts compressor noise across a storefront or an event lawn, and pins down a tractor plus a driver you probably do not need.
The freezer trailer we deliver. Built from the ground up to be dropped on a pad and to defend a temperature for as long as the job runs. It freezes deep, carries NSF approval, locks, stays quiet near guests, and lives on nothing more than one dedicated circuit or a generator.
NSF build quality and health-code compliance
Even a rented box has to satisfy the county environmental health office that licenses and inspects every food facility. Show an inspector a unit that cannot document its temperature or was not built for food contact, and they have the authority to halt service immediately.
That is a bar each of our trailers clears: NSF-approved throughout, food-safe interior surfaces, proper drainage, and a digital controller that puts the set-point in plain view. We supply the food-safe, temperature-holding hardware itself, but we are not a temperature-logging or alarm-monitoring service.
Multi-trailer setups for distribution and large operations
For a typical kitchen or market, one box does the job. Distribution floors, big fairs, and full-scale disaster response routinely need more, and because the fleet is ours, we can cluster several units and bring them online in waves as the work expands. Match the cold capacity to the operation rather than make the operation squeeze itself into one box.
Short-term emergency vs. long-term and contract storage
The clock is yours to set. Some jobs are a handful of days for an emergency or a single event. Others stretch across weeks or months for a remodel or a seasonal swell, and a few become standing contracts for businesses that want capacity parked on standby. Name your window and you will get a clean quote, no penalty for an honest "not sure yet."
Renting vs. building permanent cold storage
Building permanent cold storage is a capital project in every sense: you hire a refrigeration contractor, schedule the electrical, pull a building permit, and wait weeks before a single pallet goes inside. A rental turns that equation on its head. You bring in precisely the cold you need, for precisely the stretch you need it, and the trailer is holding temperature that same week, frequently that same day, with the commitment ending the moment your need is over.
How a trailer holds deep-freeze in triple-digit heat
Three engineered elements carry the load. Thick insulated panels and tightly gasketed doors lock the sun outside and the cold inside. A self-contained reefer condensing system specified with surplus capacity keeps stripping heat out of the box even when the air outside is brutal. And a digital thermostat locks onto your chosen number and cycles the compressor to hold the line. Run those three together and a trailer baking on open asphalt behaves like one tucked in a cool warehouse. That is also why power is the first thing we ask about: the design delivers its safety margin only on steady, uninterrupted power.
Where We Deliver Across Riverside and San Bernardino Counties
We run the valley floor daily, roughly from Chino and Ontario on the west out to Redlands, Yucaipa, and the Banning Pass, and south down the I-15 through Corona, Murrieta, and Temecula. Planned rentals are usually same-week. A real emergency is measured in minutes, not days.
Neighborhoods and towns we cover include Riverside, San Bernardino, Ontario, Rancho Cucamonga, Fontana, Corona, Moreno Valley, Redlands, Temecula, Murrieta, Menifee, Chino, Chino Hills, Jurupa Valley, Eastvale, Rialto, Colton, Upland, Perris, Hemet, Yucaipa, Highland, Norco, Loma Linda.
Riverside. The county seat, UC Riverside, and a downtown where restaurants sit in 1920s buildings with no room to grow a walk-in. The Mission Inn Festival of Lights runs from late November into January and draws up to 75,000 people on switch-on night alone. Curbside and lot-placed refrigeration is often the only way to add cold space there.
San Bernardino. Stater Bros. runs a 2.1 million square foot distribution campus on the old Norton Air Force Base site, and BNSF works its Southern Transcon intermodal terminal a few miles away. Add the NOS Events Center and Glen Helen, and you get distribution scale and event scale in one city. Emergency freezer trailer rental in San Bernardino is usually one of those two.
Ontario and Rancho Cucamonga. Air freight and retail in the same breath. Ontario International Airport moves hundreds of thousands of tons of cargo a year, Toyota Arena runs more than 125 events, and Ontario Mills is the largest mall in California. Just east, Rancho Cucamonga portable freezer trailer rentals mostly serve Victoria Gardens dining and the Fourth Street warehouse belt.
Fontana, Rialto, and Colton. Pure logistics country. The Speedway Commerce Center now covers 6.6 million square feet on the old Auto Club Speedway land, and Union Pacific opened an intermodal terminal at West Colton. Cold overflow here is about freight timing, not retail hours, so we run early morning and late night drops.
Corona, Temecula, and Murrieta. The I-15 and SR-91 side of the region. Corona sits at the worst commuter chokepoint in the area, so delivery windows matter more there than anywhere else. Further south, event freezer trailer rentals near Temecula serve 47 wineries across 33,000 acres, plus the Balloon and Wine Festival crowd at Lake Skinner.
Chino, Eastvale, and Jurupa Valley. The old dairy belt. In 1967 the county set aside 17,000 acres here as a dairy preserve, and at the late 1980s peak it held more than 400 dairies and 350,000 cows. By 2013 only 66 dairies were left. The land that once cooled the region's milk now stores its frozen freight.
Planned rentals are usually scheduled same-week, and a true emergency puts a trailer on your Inland Empire lot in about 45 minutes.
What Inland Empire Customers Say
"Our walk-in died on a Friday afternoon in July. They had a trailer in our lot and cold before dinner service. We did not lose a single case of protein."
Marisol R. · restaurant owner, Riverside"We took on a frozen account before our cold room was finished. Two trailers carried us for four months. Straight answers on the phone every time I called."
Dan K. · warehouse manager, Fontana"Three day wedding weekend, high 90s, no kitchen on site. Everything held at 38 degrees the whole time and the driver set it exactly where we asked."
Priya S. · event caterer, Temecula"Frozen rack failure on a Saturday morning. They understood the urgency without me having to explain it twice. Unit was pulling temp the same day."
Tom A. · grocery operations, San Bernardino"During a fire season shutoff we needed cold storage on a generator, fast. They had one staged and running that evening. Nobody else could even quote it."

Inland Empire Freezer & Refrigerated Trailer Rental FAQ
How fast can you get a freezer trailer to my Inland Empire location?
Planned rentals are usually scheduled the same week. For a true emergency, our 24/7 dispatch normally has a unit on your lot and pulling temperature in about 45 minutes, because the trailers are staged on the valley floor rather than over a pass. Call 866-699-5802 and tell us the cross streets.
What power does the trailer need on my site?
A dedicated 120 volt, 20 amp circuit within roughly 100 feet of where the trailer parks, or a generator that we supply. The units do not run on 208 to 240 volt building service. Most kitchens and markets in the region already have the right outlet, and we confirm it on the phone before the truck rolls.
Can one trailer hold both frozen and refrigerated product?
Each trailer holds one set-point at a time, anywhere from about 10 below zero up to roughly 50 degrees. If your load mixes deep frozen dessert with fresh produce, we will usually recommend two boxes rather than compromise on a middle number that suits neither.
Do your trailers meet county health code for food?
The interiors are NSF approved for direct food contact, with food-safe surfaces, proper drainage, and a digital controller that shows the set-point to an inspector. We supply the food-safe, temperature-holding equipment. We are not a temperature logging or alarm monitoring service, so if your program needs continuous written records you will want that vendor separately.
Can I keep food overnight at an Inland Empire event?
Yes, if it is held at 41 degrees or colder by mechanical refrigeration for the duration of the event. Perishable food held at 45 degrees has to be discarded at the end of the operating day. That difference is the main reason event vendors rent a trailer instead of stacking coolers.
How long can I keep the trailer?
As long as the job runs. Some rentals are three days for a festival or an outage. Others run weeks or months through a remodel or a seasonal build, and some customers keep a unit on standby under contract. Tell us the window you expect and we will quote that term.
Do you deliver during a fire season power shutoff?
Yes, and those weeks are exactly what we hold generator capacity for. A trailer running on a generator keeps holding temperature while the surrounding grid is off. If your site is in a shutoff zone above Highland, Yucaipa, Redlands, or the Banning Pass, call before the wind advisory rather than during it.
What size do most Inland Empire customers rent?
The 6x12 covers most jobs, at roughly fourteen pallet positions and deep freeze capable. The 6x8 suits tight retail lots and small kitchens. The 6x16 runs about twenty pallet positions for distribution, large events, and disaster work. Describe the load and we will spec it rather than push you up a size.
Will the trailer fit in an older commercial back lot?
Usually yes, though it depends on the approach more than the parking space. Older cores in Riverside, Upland, and San Bernardino have tight turns, and the newer buildings in Fontana and Perris have room to spare. We ask about the yard, the gate, and the drop point before the truck leaves so it is one clean trip.
Are you a broker or do you own the trailers?
We own the fleet. The same company answers your call, services the unit, and sends the driver. There is no reseller in the middle marking up somebody else's equipment, which is also why we can commit to a delivery time instead of checking with a supplier.
Which Inland Empire cities do you cover?
The valley floor across both counties.

The First Hour After a Walk-In Fails, and What It Costs You
Start a clock, because that is the only number that matters. Food-safety guidance treats 40 degrees as the line, and roughly four cumulative hours above it makes most refrigerated inventory unsafe to serve. On a 105 degree afternoon in San Bernardino, an unpowered walk-in gets there faster than most managers expect. So the first move is not diagnosis. It is measurement. Put a probe thermometer in the warmest part of the box, write the time on a piece of tape, and check again in twenty minutes. That reading tells you whether you have hours or minutes, and it is the record you will want later.
Second move is triage by value and by risk. Raw protein, dairy, and anything already opened come out first. Sealed frozen product in a full freezer is the most forgiving, because a packed freezer holds its own cold far longer than a half-empty one. Do not open doors to look. Every open door costs you minutes. Third move is the phone. Call for a trailer while you still have a choice about which product to save, not after the decision has been made for you. Catering freezer trailer rentals across Riverside County and restaurant calls both start the same way, with somebody who waited an hour too long.
From 350,000 Cows to Cold Freight: How the Chino Belt Changed
In 1967 San Bernardino County set aside 17,000 acres around Chino and Ontario as a dairy preserve. Dutch, Portuguese, and Basque dairy families had moved inland through the 1950s after selling out of Artesia, Cerritos, and Paramount to housing developers, and they rebuilt here. By the late 1980s the preserve held more than 400 dairies and about 350,000 cows, the largest concentration in the United States. Through the 1970s the Chino Valley was the largest concentrated milk producing area in the world.
Then the same thing happened again. Between 1978 and 2013 the number of dairies in San Bernardino County fell from 378 to 66, and the land went to warehouses. It is worth sitting with that for a second, because the cold-storage story of this region is written into it. The acreage that once chilled the region's milk now stores its frozen freight, and the buildings that replaced the barns were mostly designed for dry goods. That gap, between a food economy and a warehouse stock built for boxes, is exactly the gap a refrigerated trailer fills.
Fire Season Playbook: Wind, Power Shutoffs, and Your Cold Chain
Santa Ana conditions can show up any time from September through May, and the strongest events cluster in November, December, January, and February. The passes do the damage. Cajon and San Gorgonio squeeze the airflow and push gusts to 60 or 70 miles an hour in a strong event, with worse in the canyons. That is the setup that leads Southern California Edison to consider a Public Safety Power Shutoff, and in one extreme event the utility put more than 294,000 customers across six counties under consideration.
Build the plan before the advisory. Know whether your site is in a shutoff zone, and know how long your product survives without power, which is a shorter number than most people guess. Decide in advance what moves into a trailer and what gets sold down first. Keep a generator-capable option in the plan rather than assuming the block stays lit, because the whole purpose of a shutoff is that it happens on purpose. The fires behind these decisions are recent and local: 43,978 acres above Highland in 2024, 22,744 acres around Yucaipa in 2020, and 91,281 acres in 2003.

Temporary Food Facility Rules Event Vendors Get Wrong
The California Retail Food Code sets the bar, and county environmental health enforces it at the booth. Potentially hazardous food has to be held at 41 degrees or below for cold holding, with a thermometer in the unit. Temporary food facilities may hold perishable food at 45 degrees or colder during the operating day, but anything sitting at 45 has to be discarded when the day ends. Hold it at 41 or colder with mechanical refrigeration and you can keep it overnight for the run of the event. For a three day festival, that one distinction is the entire budget difference.
Two more rules catch people out. On mobile food units, ice and dry ice are not accepted as the only method of holding temperature, and mechanical refrigeration meeting NSF Standard 7 or equivalent is required for potentially hazardous food. And on the paperwork side, Riverside County wants the community event organizer permit at least two weeks ahead, with events capped at 25 operating days in any 90 day period. Sort the cold holding first, because it is the part you cannot fix on the morning of the event.
Sizing Cold Storage for an Inland Empire Event
Start with the venue, not the guest count. Glen Helen Amphitheater seats 65,000 and is the largest outdoor music venue in the country. The NOS Events Center covers more than 120 acres with 150,000 square feet of indoor exhibit space. Toyota Arena runs more than 125 events a year. Downtown Riverside packs up to 75,000 people onto the street for a single Festival of Lights switch-on night. Each of those is a different cold problem: a vendor row, an exhibit hall, an arena kitchen, and a street festival with no back of house at all.
Then count holding, not serving. The mistake we see most often is sizing to what goes out the window per hour instead of what has to sit cold between services. A vendor row of twenty booths over three days is a holding problem, and it is usually one 6x12 rather than twenty coolers. A single arena show is often a 6x8. A multi-day festival with a camping crowd is 6x16 territory, sometimes two. And if the site has no dedicated 20 amp circuit, plan on a generator from the start rather than discovering it at load-in. Cold storage trailer rentals for Inland Empire breweries and beverage vendors follow the same logic, since keg temperature is a holding problem too.
