How many pallets of cold storage does your Arizona site need? A sizing worksheet
Most people size a cold storage trailer by guessing. A better way takes ten minutes and a notepad. Start with what you are storing, how many pallets or cases, and how long you need the space. The answer decides whether you need one trailer, two or a trailer plus your existing cooler.
Step one is the load. Count pallets for a plant, or cases and tubs for a caterer or ice cream shop. If you do not know, count what filled your last cooler and add what you could not fit. Write down the packaging too, because bulky boxes of flowers use more space than dense cases of frozen product.
Step two is working room. A trailer that is packed wall to wall is hard to unload, so leave a clear aisle. Kitchens that open the door all day need more aisle than a plant that loads once. Add about a third to your count for walking space and loop us in if your crew works inside the trailer.
Step three is temperature. If your load includes frozen and chilled product, plan two trailers, or load the mixed set at the coldest item's setting. A florist and a caterer on the same weekend usually want separate units for that reason.
Step four is duration. A one day event needs the trailer for delivery, use and pickup. A plant remodel needs it for weeks. Longer rentals call for a service schedule, so brief us on the date range at the quote stage. The same team handles delivery, service and pickup.
Here are two worked examples. A caterer with 40 cases of proteins, 30 cases of drinks and 20 cases of desserts for a Saturday wedding needs one chilled trailer with room for racks. A packer with 24 pallets of produce for a harvest week needs one trailer for the load and a second if the pallet count climbs midweek.
Step five is the site. Check where the trailer will sit, how the door will face and whether the service truck can reach it. Send a photo of the spot and we can suggest placement. Mavirus Group will also confirm hookup needs in the quote so your electrician or generator is ready.
When you have those numbers, reach our team or start a quote online. A person answers, asks the short list of questions above and gives you a plain answer on size. If you also need restrooms or a break area on the same site, see our freezer trailer rentals in Colorado for projects that cross into the Four Corners.
What to ask any cold storage trailer company before you sign
Cold storage rentals are easy to compare on a quote and hard to compare on what happens later. A short list of questions helps you tell the difference. Ask them of any company, including us.
Ask who owns the trailers. A direct rental company owns its fleet and does not borrow units from others. That matters when something goes wrong, because the company that owns the trailer can fix or replace it without calling around.
Ask who answers the phone. A business that sends you to a menu or a ticket form is hard to reach at 2 a.m. when a unit trips. When a unit trips in the middle of the night, a real person picks up, and the same crew that delivered your trailer is the one that comes to service it.
Ask what is included. Delivery, setup, service and pickup should be in the quote, and so should the hookup needs. If a company leaves out one of them, you will pay for it later in time or trouble. Also ask what set points the unit can hold. Ours runs from -10°F to 50°F.
Ask about the swap process. If a trailer has trouble, what happens next, and who moves your product? A clear plan is a good sign. A shrug is not.
Ask about placement. A good company asks about ground, door position, access for the truck and distance to power. These questions save you a failed delivery and a second trip. We ask for a photo of the spot when the site is unclear.
Ask about paperwork. Agency and corporate buyers need an insurance certificate, a W-9 and PO and invoice details. Ask for them early so purchasing is not waiting on the trailer. Our team helps with vendor setup when asked.
Ask what else the company can supply. Many sites that need cold storage also need restrooms, showers, laundry or drinking water. One vendor for all of it means one schedule and fewer calls. Arizona's new heat rules ask outdoor job sites to provide water, shade and a place to rest, and we can supply drinking water along with your cold storage.
Finally, ask how soon you will hear back. A quote that arrives the same day is a good sign. Call us or send a request and see for yourself.
A seasonal calendar for renting cold storage in Arizona
Arizona runs a calendar that most states do not. The heat of summer pushes events and weddings into the cooler months, and that means cold storage demand piles up from October through April. Here is a simple month by month look.
October and November bring the Arizona State Fair, the first wave of weddings and a run of fall festivals. Caterers, florists and vendor rows start asking for trailers. Plants also add product for holiday orders, and grocers plan their remodels around the quiet weeks that follow.
December runs through the Fiesta Bowl period in Glendale and holiday parties across the Valley. Food service, catering and event staging take over the calendar. Cold storage for stadium lots, tailgates and charity meals is the typical request.
January is Barrett-Jackson at WestWorld in Scottsdale and the start of the Tucson gem shows. Vendors fill hotel lots and temporary yards, and many have no cold space. February also brings the Phoenix Open to TPC Scottsdale, and the Tucson rodeo draws crowds that need cold storage close by.
March brings spring training and the Chandler Ostrich Festival. Food booths run through product quickly in these crowds. April closes the peak with weddings, graduation parties and the last of the cool weather. If you plan a spring event, send your date and pallet count early.
May through September is the hot stretch. Events thin out, but plants and ice cream shops work harder, and monsoon storms can cut power or close roads between mid-June and late September. Cold storage demand shifts from events to production and relief work.
Wildfire season follows the heat in the high country. Evacuations can turn school gyms and community centers into shelters in days, and those buildings do not have the cold space to hold donated food. Planning ahead for a feeding site is the best move.
Whatever the month, the pattern is the same: call with your date, site and pallet count, and our team will tell you what fits. A person answers every call, and the quote does not take long.
How to load, cool and hold product in a rented freezer trailer
A rented trailer is only as good as the way you use it. A few habits make the difference between a clean hold and a rough week. These steps work for food plants, caterers, florists and relief kitchens alike.
Pre-cool the trailer before you load. Plug it in, set the temperature and let it reach the target while empty. Loading warm product into a warm box makes the unit work hard, and it may not recover on a hot Arizona afternoon.
Chill product before it goes in. A trailer holds a temperature, but it is not built to pull heat out of a truckload of warm goods. If your product arrives warm, stage it in the coolest area available and load in batches.
Leave room for air to flow around everything you load. Stack pallets so air can flow around them, leave a gap at the walls and keep product off the floor on racks or pallets. Blocking the evaporator or stacking to the ceiling causes warm spots and uneven temperatures.
Limit door time. Plan the load in the order it will be used and group trips together. Each opening lets in warm air, and in July the difference is noticeable. A strip curtain on the door helps in busy kitchens, and our team can talk through the options.
Match the set point to the product. Cold holding tops out at 41°F under the food code, while frozen goods need to stay solidly frozen. Ice cream wants the deep freeze end of the range, flowers want a cool, steady setting and produce lands in between. The FDA publishes the full code at the Food Code reference.
Check the unit on a schedule. Walk by the display, look at the temperature and write it on a log if your inspector expects one. If the reading drifts, call. A person answers, and the team moves quickly on swaps.
Keep the area around the trailer clear. Do not block the vents, keep the ground level and keep the access path open for the service truck. In monsoon season, watch for water pooling beneath the trailer.
When you are done, empty the trailer and leave it closed for pickup. Mavirus Group collects it with the same crew that delivered it. For the USDA's guidance on safe food handling, see the USDA Food Safety page.
