#1 Freezer & Refrigerated Trailer Rental Company in California

No state moves more cold product than California. The USDA’s October 2025 refrigerated-warehouse survey put California first in the country at 400 million cubic feet of gross capacity, well ahead of Georgia and Washington, and roughly 17% of every refrigerated facility in the nation sits inside our borders. That’s the Central Valley’s harvest, the biotech labs around the Bay, and the perishables pouring through the ports of Los Angeles, Long Beach, and Oakland. When any of that cold chain hits a gap, a KryoFridge trailer fills it. Here’s who calls us across San Diego, California,, and why.

Agriculture and produce cold-chain

The San Joaquin Valley grows a big share of the country’s fruits, nuts, and vegetables, and almost all of it needs to hit a cooler within hours of leaving the field. Packing houses around Fresno, Bakersfield, Visalia, and Salinas run flat-out during harvest, and a single cold room going down at the peak of stone-fruit or grape season can cost a packer five figures in a morning. We back-stop that. When a room fails or the line outruns the in-house capacity, our reefer trailers hold the fruit cold off Highway 99 until things are back online. Dairies, floral growers, and cannabis operations lean on the same units when their own refrigeration runs short.

Film, TV, and production

California more than doubled its film and TV tax credit to $750 million in 2025, and the production work that brings keeps location shoots rolling across Los Angeles and the high desert. On-set catering crews feed dozens to hundreds of people a day, and a remote shoot rarely has a building kitchen to lean on. A self-contained trailer that runs on its own power and holds 0°F to 50°F keeps the protein, dairy, and fresh produce safe whether the unit base is in Griffith Park or a dry lakebed near Palmdale. When the catering truck needs overflow cold storage, that’s us too.

Grocery and cold-chain distribution

California’s grocery distribution runs deep, from the big Central Valley DCs feeding the western states to the urban stores in the Bay Area and Southern California. Racks fail. Docks overflow. Stores remodel. When a grocery refrigeration system goes down or a remodel pulls the walk-ins offline, our reefer trailers keep the cold chain intact. Safeway, Vons, Raley’s, Stater Bros, Sprouts, and independent markets across the state all hit those gaps during peak runs and renovations, and a trailer at the dock buys them the time to fix it without dumping product.

Restaurants, hospitality, and catering

California has more restaurants than any other state, and every one of them runs on refrigeration that eventually breaks. A walk-in failure during a busy weekend in San Diego or San Francisco can spoil thousands of dollars of inventory and pull a kitchen in front of a health inspector. We drop a refrigerated trailer at the back dock so the kitchen never stops serving. Caterers staging food for weddings, galas, and corporate events use the same trailers to hold cold beyond a venue’s built-in capacity.

Festivals, stadiums, and outdoor events

Coachella in the Indio desert, Stagecoach, BottleRock in Napa, and stadium runs at SoFi, Levi’s, Oracle Park, and Petco all need cold storage that lives on the grounds, away from any fixed walk-in. Vendors and concession operators rent our trailers to keep food and beverage cold through events that punish equipment in open sun. The trailers go where the crowd is and hold their setpoint while they’re there.

Hospitals, labs, and pharmaceutical cold-chain

California’s hospitals, biotech labs, and pharmacies store vaccines, medications, and temperature-sensitive product that can’t tolerate a warm refrigerator. When a medical-grade unit fails or a facility loses power during a heat event, our trailers provide backup cold storage at the precise temperatures these products require. The Bay Area biotech corridor and the big hospital systems statewide both call when a backup is the difference between keeping product and writing it off.

Construction and facility build-outs

New grocery stores, restaurants, and cold-storage facilities go up across the state every year, and the months between breaking ground and a working walk-in still need refrigeration for staging and worker catering. A trailer bridges that gap so the project keeps moving while the permanent system gets installed.

Picking the right size for the job

The 6’x8′ (268 ft³) handles a single kitchen’s overflow or a small catering run. The 6’x12′ (416 ft³) covers most restaurants and mid-size events. The 6’x16′ (564 ft³, 6,690 lb payload) is the one for full catering operations, grocery dock backups, and harvest-scale loads. Every unit adjusts from 0°F to 50°F, so you can run it as a freezer one week and a walk-in cooler the next.

Not sure which fits? Call us at (866) 699-5802 and tell us the job. We’ve staged trailers at every kind of California site there is, a Salinas packing shed, a Hollywood backlot,, and we’ll size it right the first time.

California weddings and events run hot, especially inland. California and the Valley regularly push past 100°F in summer, and even a coastal venue can bake during a September heat spell. Throw a wedding, a winery gala, or a festival into that, and the food and beverage logistics get serious fast. KryoFridge keeps it all cold, the champagne, the wedding cake, and everything between, with refrigerated, freezer, and walk-in cold storage trailers that hold steady when the venue’s built-in coolers tap out.

We run three sizes: the 6’x8′ (268 ft³, 3,000 lb payload), the 6’x12′ (416 ft³, 4,300 lb payload), and the 6’x16′ (564 ft³, 6,690 lb payload). Each adjusts from 0°F to 50°F and runs on a standard 110V circuit, so it drops into almost any Napa vineyard, Los Angeles rooftop, or open-field venue without a special hookup.

Why event cold storage matters more here

Food safety isn’t optional, and a triple-digit Valley afternoon makes it harder. Dairy, seafood, and proteins need consistent refrigeration or they turn fast. Our trailers hold the temperature you set so the catering team isn’t babysitting ice and praying. Beverages are the other half of the job. A California reception goes through staggering volumes of wine, champagne, and cocktails, and a 6’x16′ chills enough to keep a 400-guest bar stocked and cold all night.

Then there’s dessert. Buttercream cakes, gelato bars, and plated desserts melt in a warm room. We hold them at exactly the temperature they need until service, so what comes out of the trailer looks like what the pastry chef built.

Catering flexibility for complex menus

Big California events rarely run one simple menu. You’ve got pre-prepped dishes, on-site cooking stations, and multiple service points spread across a ballroom or festival grounds. A refrigerated trailer parked near the action means chefs aren’t running back to a distant kitchen between courses. Pre-plated dishes hold until they’re called. Ingredients stay close to the line. And when you’ve got food stations scattered across a property, we can stage a trailer to feed each one.

Wine country and outdoor venues

Outdoor weddings and receptions are everywhere in this state, Napa and Sonoma vineyards, Santa Barbara estates, and Temecula wineries. The catch is that beautiful open-air venues rarely have the kitchen infrastructure to match. Our trailers bring the refrigeration to the site so the caterer can run a full menu instead of a limited one. The self-contained design means you’re not depending on the venue’s stressed HVAC or a single overloaded outlet.

For festival-scale events like the food courts at Coachella or a concert run at SoFi Stadium, the math is simple. Vendor cold storage has to live on the grounds, and it has to hold in heat that punishes equipment. Our trailers are built for exactly that.

Built tough, hygienic, and quiet

Each trailer uses one-piece fiberglass construction with 4-inch insulated walls rated R-28, 54-inch reinforced doors, and pallet-duty floors that take a loaded pallet jack. The interior carries an antimicrobial gel coating, which matters when you’re storing food for hundreds of guests. The all-electric refrigeration runs clean and quiet, so a trailer humming behind a wedding tent won’t drown out the toast.

Fast delivery and around-the-clock support

California events change on a dime. A guest count jumps, a second bar gets added, a heat wave rolls in. We deliver fast across Los Angeles, San Diego, the Bay Area, California, and the Central Valley, often same day, and we’re reachable 24/7 if something shifts the night before. Your driver sets the unit up, walks your crew through the controls, and we’re a phone call away through the whole event.

When a walk-in dies at 2am or the grid drops during a 108°F afternoon, you don’t have days to figure out cold storage. You have minutes before product starts turning. KryoFridge runs 24/7 emergency reefer and freezer trailer delivery across California, with units that pull down to 0°F and hold it through the worst a Valley summer throws at them. Here’s how that lifeline works when things go sideways.

Walk-in failures and refrigeration breakdowns

This is our most common emergency call. A compressor seizes, a refrigerant line leaks, or a condenser quits under load, and suddenly a Los Angeles kitchen or a Fresno packing house is staring at thousands of dollars of perishables with nowhere to put them. Repairs aren’t instant. A failed walk-in can stay down for days while parts come in. We bridge that gap, dropping a refrigerated trailer at your dock so nothing spoils while the techs work. The same goes for grocery refrigeration racks and ag cold rooms. When a system goes down at a store or a Central Valley distribution dock, our trailers keep the cold chain intact.

Heat events and grid stress

California heat is a demand driver all by itself. Inland valleys run stretches where afternoon highs sit above 105°F for a week straight, and that kind of heat overworks every refrigeration rack in the region. Overworked compressors fail. When the grid sags under air-conditioning load during a Flex Alert and the power flickers, fixed refrigeration goes dark. A trailer with generator capability keeps product cold straight through an outage that would otherwise wipe out a freezer full of inventory.

Power outages and PSPS shutoffs

Outages don’t only come from heat. Public Safety Power Shutoffs during fire season, equipment faults, and grid issues all knock out refrigeration without warning, sometimes for days in the foothills and rural counties. For grocery stores, restaurants, packers, and any operation running on a walk-in, an extended outage means total loss unless there’s backup cold storage on site. We stage trailers as that backup, often within a couple hours of the call, so the product survives the outage instead of the dumpster.

Wildfire and disaster relief

California’s fire seasons displace people and disrupt food and medical supply chains every year. Relief operations and evacuation centers need cold storage for food, water, and medical supplies, often somewhere a fixed walk-in doesn’t reach. Our mobile units go wherever the staging area is, providing safe cold storage for perishables and essential goods when the normal infrastructure is stretched thin or offline. Cooling centers during heat emergencies lean on the same trailers to keep water and supplies cold.

Medical and pharmaceutical cold-chain

California hospitals, biotech labs, and pharmacies store vaccines, medications, and temperature-sensitive product that can’t tolerate a warm refrigerator, especially during a power event in extreme heat. When a medical-grade unit fails or a facility loses power, our trailers provide backup cold storage at the precise temperatures these products require. It’s a quieter use case than a restaurant rescue, but when it comes up, the stakes are high and the response has to be fast.

What makes our trailers ready for emergencies

The fleet runs all-electric refrigeration on a standard 110V circuit, with no fuel to source mid-crisis. One-piece fiberglass construction, 4-inch R-28 insulated walls, and 54-inch reinforced doors mean the box holds its temperature even when it’s parked in direct sun. The antimicrobial gel coating keeps the interior safe for food and medical product alike. And the 0°F to 50°F range means one trailer covers everything frozen inventory, chilled produce, and medical storage.

Why speed is the whole game

In an emergency, response time is everything. We keep trailers staged across the state and dispatch around the clock, so we can reach a site in Los Angeles, San Diego, the Bay Area, California, or the Central Valley fast when the call comes in. Our drivers handle delivery and setup so the unit is cold and running quickly, not sitting on a trailer in your lot waiting for someone to figure it out.

If your walk-in just went down or you’re staring at a heat-driven outage, don’t wait for product to turn. Call (866) 699-5802 anytime, day or night, and we’ll get a trailer to you.
