KryoFridge sets the bar for walk-in freezer trailer rentals in Longmont

Any trailer looks good sitting empty in a yard. The real test is a busy Saturday, when the door opens every minute or two and the sun is on the roof all afternoon. Our trailers hold their set-point through that kind of day because the cooling units are sized with room to spare, and we check each one before it leaves our yard. We own every trailer we send out, and we have more than 30 years in the rental business. Call us or request a quote and we will set a delivery window that fits your week.

One box, any temperature

Set it for a hard freeze or a gentle cool. If your plans change halfway through the rental, we reset the number instead of hauling in a new trailer.

Simple power

A dedicated 120-volt, 20-amp circuit is all it needs. No outlet in reach? We bring a generator.

A direct fleet owner

We are a direct fleet owner, not a reseller. If something goes wrong at night or on a weekend, our 24/7 line reaches a real person who can send help.

National restaurant brands

McDonald's, Chick-fil-A, Dutch Bros, Burger King, and Panda Express have trusted KryoFridge with their cold storage. A single Longmont kitchen gets the same care.

Licensed, insured, and registered

We are licensed and insured, SAM.gov registered for public agencies, and backed by an A+ BBB rated network. That keeps the paperwork easy for schools, fairs, and property managers.

National chains we keep cold for Longmont crews

If the nation's largest chains trust us to protect their inventory, your kitchen is in good hands. These are brands that vet a cold-storage partner the same careful way they vet a food supplier, and they keep calling us back.

Who handles it, Longmont

The 16 ft Utility: the walk-in freezer trailer we send when a Longmont-area job cannot fail

In Longmont the 16' Utility gets the most calls, because it takes full pallets of produce through the rear doors and still fits beside a farm stand, a garden center, or a store dock off Main Street.

The flagship 16' Utility mobile cold storage unit, plugged-in for rental in Longmont
16' insulated boxRear double doors + side utility third door-10°F to +50°F range120V/20A or generatorTandem axle

The 16' Utility earned its flagship spot the hard way, on jobs where a few degrees of drift would have cost somebody their inventory. The box is 16 feet long and fully insulated, riding on a tandem axle. The interior is NSF approved. One digital set point covers everything from -10°F frozen storage to a 50°F produce cooler. There are two ways in: rear double doors for pallets, and the side utility door for everyday grab-and-go.

Because we own and service the entire fleet, the trailer on your lot was prepped in our yard, not scrambled together after your call. It lives on a dedicated 120V, 20-amp circuit or a generator we supply, and it keeps its temperature whether the job runs a weekend or a full season.

Other Longmont jobs for our mobile refrigeration rentals

Most of our work around Longmont falls into three groups. Garden centers and flower sellers need cool, steady space in spring and wedding season. Farms need a place to hold the harvest when it all comes in at once. Seafood and produce sellers need extra room when a truck arrives early or a cooler goes down.

🚨 Wind shutoff backup

Xcel has cut power to parts of Boulder County during high-wind fire weather. We bring a trailer with a generator so frozen stock stays safe until power returns.

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 Longmont instead of a couple counties down the freeway, "can I get it today" is an ordinary ask here, not a stretch.

How Longmont-area owners price out a failed cooler

In practice, Longmont

Add it up the way an owner in Longmont 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 one is booked with a single call.

How our portable freezer trailers handle Longmont heat, hail, and cold

Longmont sits at about 4,981 feet and gets more than 300 days of sun a year. July highs usually run in the upper 80s to low 90s, and the city has hit 106 degrees twice. A trailer on a sunny lot works harder than a cooler inside a building, so our units carry cooling capacity with room to spare.

Hail is the local wild card. June is the peak month, and big storms roll off the foothills with little warning. Our trailers are built with thick insulated walls and a sealed box, so the product inside stays safe and cold when a storm rolls across the site in the middle of the afternoon.

Winter swings the other way. Cold snaps can push well below zero, and the city's record low is 38 below. That matters for produce and flowers held in a cooler. The same digital control that holds cold in July keeps a cooler box from getting too cold in January, so fresh stock does not freeze.

Cooler trailer rentals for Longmont garden centers and flower sellers

Longmont has a long list of family garden centers and plant growers, several of them clustered along Nelson Road and the county roads north of town. Spring is their make-or-break season, and the busy weeks stack up fast from late April through early June. Truckloads of bedding plants and vegetable starts arrive in a few big waves before Mother's Day, and there is rarely enough bench space for all of it at once. Some of it has to wait in the back, and the back of a garden center in May is often hot and bright by noon.

A cooler trailer set between 40 and 50 degrees gives a garden center a holding room for stock that comes in before it can go on display. Plants stay out of the afternoon sun and out of the way of a sudden hail storm, which matters here. On July 28, 2026, hail the size of a baseball fell near Longmont, the largest in the county's ten-year record.

Flower sellers use the trailer for event weeks. A wedding or a big holiday order means dozens of arrangements that all have to stay fresh until the van loads. A 6x8 or 6x12 behind the shop holds buckets and finished pieces near 36 degrees, and staff can walk in and work without warming them.

We ask two things before we set the number. What is the most delicate item you are holding, and how often will the door open? Cut roses like a steady cool box with few trips, while plants in pots can handle more traffic. Tell us your mix and we will suggest a size and a set-point, then deliver the trailer already cold.

Freezer and cooler trailer rentals in three sizes for Longmont

We rent three sizes, and each one is a real walk-in box on wheels. The 6x8 is the compact unit for a flower shop or a coffee stand lot. The 6x12 is the middle size that works for a small farm or a caterer with a full weekend.

The 16' Utility is our signature trailer. It is a self-contained 6x16 box on a tandem axle with rear double doors for pallets. A side door lets your staff grab a single case without letting the cold pour out the back.

Every unit holds one digital set-point between about 10 below zero and 50 degrees, and the inside is NSF-approved for food contact with a floor drain for wash water. Power comes from a dedicated 120-volt, 20-amp circuit within about 100 feet, or from a generator we bring along. We serve all 50 states, and if your company also has sites down the Diagonal, our Boulder freezer trailer rentals use the same trailers and the same paperwork.

Refrigerated trailer rentals for St. Vrain Valley farms at harvest

Farming built Longmont. The town started as the Chicago-Colorado Colony in 1871, a vegetable canning plant opened in 1889, and a beet sugar factory went up on the east side in 1903 and ran until 1977. Farms around the St. Vrain Valley still grow vegetables and raise meat for local markets today. Many of them sell at the Saturday market, to local stores, or straight to families who drive out to the farm.

Harvest windows here are short, and the weather does not wait. A hail storm off the foothills or an early frost can push a farm to pull a whole crop in a day or two. A trailer set near 34 degrees at the edge of the field gives the crew a place to cool greens and sweet corn right away instead of letting them sit in the heat.

The Longmont Farmers Market runs Saturday mornings from April into late November at the county fairgrounds, and it draws more than 60,000 visitors a season to over 100 growers-only booths. Many of those growers pick on Thursday and Friday so the produce is as fresh as it can be on market day. A cooler trailer at the farm holds the load overnight so it goes to market cold and fresh.

Meat and egg producers use us too. A temporary freezer trailer set well below zero holds processed pork, beef, or lamb when a farm's own freezers fill up after a processing date. We place the trailer where your truck can back up to it, and we check the power plan with you before delivery.

Freezer trailer rentals for Longmont seafood and produce sellers

Fresh fish and fresh produce have the same weak spot. Neither one forgives a break in the cold between the truck and the shelf. Longmont has seafood sellers, natural food grocers, and restaurants that bring in fish flown in from the coasts, and a short delay at the dock can cost a whole shipment.

A mobile freezer trailer at the back door gives a seafood seller room for frozen stock when a new load lands before the old one sells through. We set the 16' Utility well below zero for frozen fish, or around 32 to 34 degrees for fresh product on ice, and park it where a pallet jack can reach it.

Produce sellers use us for remodels and repairs. When a store swaps out its produce cases or its walk-in compressor quits in July, all of that stock needs a safe place to wait. A cooler trailer holds it at the right temperature until the new cases are ready.

Downtown work adds another reason. The new transit hub at 1st Avenue and Main Street and other street projects can close alleys and loading zones for days at a time. A trailer parked on the side that stays open keeps deliveries moving while the crews work.

A working guide to set points for portable refrigeration near Longmont

"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 Longmont, 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.

ProductTarget holding bandTrailer mode
Ice cream and frozen desserts-10°F to 0°FDeep freeze
Frozen proteins, seafood, prepared meals0°F or belowFreezer
Fresh meat and poultry (short hold)28°F to 32°FRefrigerated
Dairy, deli, packaged produce34°F to 38°FRefrigerated
Beverages, florals, catering trays38°F to 45°FRefrigerated

One figure matters more than 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 Longmont 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. 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.

What a cold chain trailer needs once it lands on a Longmont-area 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 Longmont 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 storm or a utility outage 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 Longmont layout cold, so the delivery is one clean trip instead of a guessing game on the property.

Plan around it, Longmont

A typical setup for a garden center before Mother's Day

A typical setup for a garden center with a big spring delivery places a 6x12 beside the sales yard a week ahead, set near 45 degrees. The crew loads flats as the trucks arrive and pulls them out as bench space opens. We keep the unit in place until the rush is over and then pick it up.

A typical setup for a farm on harvest week

A typical setup for a vegetable farm at harvest puts a 16' Utility at the edge of the field, set near 34 degrees. Pickers load crates straight into the rear doors, and the farm truck pulls from the side door for market runs. We check the generator plan before delivery when the field has no power.

A typical setup for a seafood seller during a compressor repair

A typical setup for a seafood seller with a failed walk-in places a temporary freezer trailer at the back door, set well below zero. The staff moves frozen stock across in one pass and keeps fresh fish on ice inside the store. The trailer stays until the walk-in holds temperature again.

We plan around downtown street work. Street and transit projects near 1st Avenue and Main Street can close lanes and alleys for days. We route drivers around the work so your trailer shows up when your crew is ready.

How a refrigerated trailer rental in Longmont actually goes

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.

Step 1 · Tell us about the job

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.

Step 2 · We match the unit to your space

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.

Step 3 · We set it, plug it in and cool it

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.

Step 4 · Run it, and service stays ours

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.

Keeping your walk-in freezer trailer rental ready for inspection

Food safety

Colorado bases its retail food rules on the FDA Food Code. Cold food has to stay at 41 degrees or colder, and frozen food should stay frozen solid. Our trailers hold a steady digital set-point, and most customers add their own thermometer and a simple log so the inspector can see the history.

Boulder County Public Health inspects food businesses in Longmont and runs a separate license track for temporary events like the fair and the farmers market. If you use a trailer as extra storage for a licensed kitchen, tell your inspector ahead of time and treat it like part of the kitchen. Keep food on shelves or pallets, store raw meat below ready-to-eat items, and label what goes in.

Our walls and floors are NSF-approved for food contact and are cleaned before each rental. Event vendors may be asked where their cold storage will sit, and we can share the trailer size and power needs for a site plan. The same state rules apply up the road, so refrigerated trailer rentals in Greeley follow the same checklist.

How our freezer trailers hold up in a health-code inspection in Longmont

  • 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.

Picking a trailer footprint for your Longmont-area site

Our signature 16 foot Utility series leads the fleet. It is the trailer we send on most jobs, and crews like it for the side utility access door. We build three footprints in all, so a single kitchen holding overflow stock has a fit and so does a distribution floor in a disaster. Every unit is dual purpose by design: one adjustable system swings between freezer and refrigerator on a digital set point. Each trailer runs on a dedicated circuit or on a generator.

6x12Grocers, caterers, mid-size eventsDeep-freeze capable
6x8Tight lots, small kitchens, short overflow-10°F to 50°F

All three sizes switch between freezer and cooler mode, so the choice comes down to footprint and how much product you need to hold.

Our 6x8: the compact unit for a few pallets near Longmont

It's 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.

Our 6x12: the workhorse for restaurants and markets near Longmont

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 trailer, the heavy-duty pick near Longmont

Our biggest footprint, 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? Most customers land on the 16 foot Utility, and we will tell you honestly if a smaller footprint covers your job. Tell us roughly what you are storing and for how long, and we will spec it for you.

Deeper questions about cold chain trailer rentals in Longmont

The questions that surface once the basics are settled. Tap any topic to open it.

Which to rent for a grocer: freezer trailer, walk-in or reefer truck

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 burns 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.

Food-safe construction and an inspector

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.

How we stage multiple trailers for high-volume sites

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 or contract storage for a build-out?

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."

Rent or build? What makes sense for a small market

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 within days, not months, with the commitment ending the moment your need is over.

What keeps the box cold in peak summer 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. 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.

Everything Longmont renters want to know about reefer trailer rentals

How do I power the trailer if my farm field has no outlet?

The trailer needs a dedicated 120-volt, 20-amp circuit within about 100 feet, or a generator. Most field edges and fair lots have no outlet in reach, so we bring a generator along. At a store or shop, a circuit that nothing else draws from works fine. We ask about power when you book so there are no surprises on delivery day.

Do the trailers come with shelving, or do I need to bring racks and a ramp?

Most customers stack product on pallets or bring their own rolling racks and shelves from the shop or the barn. The rear doors open wide for pallets, and the side door works for single cases. If you need help with loading, like a ramp for hand trucks, tell us when you book and we will talk through what fits your site.

Will a 6x12 hold my harvest, or should I rent the 16' Utility?

It comes down to volume and door traffic, because a 6x12 holds a good number of crates or cases on shelves and suits a small farm or a single shop. If you are loading full pallets, or several people will be in and out all day, the 16' Utility is the better fit. Tell us your crate count and how busy the door will be, and we will size it for you.

Can the trailer go cold enough for frozen seafood and warm enough for flowers?

Yes, each unit covers about 10 below zero up to 50 degrees. Frozen fish and meat do best at zero or below, while fresh produce sits near 34 degrees and many flowers like 36 to 45. The box recovers quickly after short door trips, so load in batches instead of leaving the door open.

Is the quote based on size alone, or do other things change it?

Size is only one part of it, and the rental length, whether we bring a generator, how far the site is, and how easy it is for a truck to reach the spot all shape the quote. A rush call on a holiday weekend is planned differently than a delivery booked weeks ahead. Call us with your dates, the address, and what you are storing, and we will give you a clear quote.

Where do I start if a health inspector will see the trailer?

Start by treating it like part of your kitchen, which means you keep food on shelves or pallets, store raw meat below ready-to-eat items, and keep a thermometer and a simple log inside. Our interior surfaces are NSF-approved for food contact and cleaned before each rental. It also helps to tell Boulder County Public Health about the extra storage ahead of time.

What weeks should I book early in Longmont?

Spring flower season, the Boulder County Fair in early August, harvest from late summer into fall, and the holidays are all busy. We suggest calling four to six weeks ahead for those dates. If a storm or a breakdown hits without warning, call our 24/7 line anyway and we will do what we can.

When a heat wave or a hard freeze hits, will the trailer hold temperature?

Yes. Thick insulated walls and a cooling unit with room to spare hold the set-point on a hot afternoon. In a cold snap, the same digital control keeps a cooler box from dropping too low, so produce and flowers do not freeze. Parking so the doors face away from the afternoon sun helps in summer.

Do you deliver to Niwot, Firestone, Berthoud, and Lyons?

Yes. We deliver across Longmont and the St. Vrain Valley, including Niwot, Firestone, Frederick, Mead, Berthoud, and Lyons. We also serve Boulder, Greeley, Fort Collins, and the rest of Colorado, and service reaches all 50 states.

Is a self-contained freezer trailer a good backup during a wind power shutoff?

It can be. If your building loses power, a trailer with its own generator can hold frozen and cold stock until the lights come back. Watch for shutoff notices on high-wind days and call us early, before the power goes out.

A harvest cold storage checklist for St. Vrain Valley farms

Harvest on the northern Front Range comes fast and ends fast, and most farms feel it in the same few weeks. A week of good weather can bring in more produce than a farm's own cooler can hold, and one hail storm can force a crew to pick everything at once. A plan made in June saves product in September.

Start with your biggest week, and look back at last season to count the crates or bins you had to cool on your heaviest single day. That number tells you whether a 6x12 is enough or whether you need the 16' Utility.

What to ask before you rent a cooler trailer in Longmont

Renting a cooler or freezer trailer is simple when the details are sorted out first. Most problems we see come from a small miss, like a circuit that was not really free or a spot the truck could not reach. Here are the questions we walk through with Longmont customers.

What are you storing, and at what temperature? Frozen seafood and meat want a hard freeze. Produce, dairy, and prepared food want cool air. Flowers and plants often want it a bit warmer. The answer sets the number on the controller.

Rent or build? Adding cold storage to a Longmont farm or shop

Growing farms, garden centers, and food shops all reach a point where the cooler is always full. The choice is between building more cold space and renting it when you need it. Each one fits a different kind of business.

Building makes sense when you are full every week of the year. A new walk-in needs planning, a contractor, electrical work, and often a permit, along with floor space or a pad you will not get back.

Planning cold storage for a food booth at the Boulder County Fair

A county fair booth is a small kitchen with a very long shift. The fair in Longmont runs five days in early August, the lot is hot, and the nearest store is a drive away. Cold storage planning decides whether you sell out of food or run out of time.

Start with your menu and your busiest day. Count the servings you expect on the biggest day, and work backward to the cases of meat, drinks, and ice you need on site.
