Refrigerated Trailers.
An insulated, stainless-lined box with the condenser on the outside and nothing in the way on the inside.
What they are
Refrigerated Trailers Built To Order.
Built to last with the best insulation and transportation capabilities, our refrigerated trailers are a different animal from the concession line — there is no serving side and no cooking, so every decision goes into holding temperature and standing up to being washed down.
The box is lined in stainless through the walls and ceiling, over an aluminium floor with drains so it can be cleaned properly rather than wiped out. The refrigeration unit mounts externally, which keeps the condenser out of the cold space and off your usable floor. Inside, E-track rails at two heights take shelving that can be moved as the load changes.
These get used for catering overflow, event cold storage, produce and beverage distribution, and as a cold room that can be parked where the work is.

What goes into them
Specified Around The Work.
Every one of these is engineered to its own spec. The list below is what we build in most often — not a fixed package.
Insulated, stainless-lined box
Walls and ceiling lined through, so the whole interior can be washed down.
Aluminium floor with drains
Pallet-duty floor that takes loading traffic and drains when you clean it.
External refrigeration
Condenser mounted outside the cold space, keeping the floor clear.
E-track and shelving
Rails at two heights down both walls so shelving moves with the load.
Sizes
From compact 5′ and 7′ cooler builds up to full 8.5′-wide insulated boxes.
Rear access
Insulated rear doors sized for how you actually load it.

What to Know About Refrigerated Trailers
While the refrigerated or “reefer” trailer business has not actually been around for very long, it’s extremely important. Delicate and perishable freight such as fresh produce and medical supplies will spoil long before they reach their destination if they aren’t kept at sufficiently cold temperatures, and this is exactly what refrigerated trailers are designed to do. Here’s what to know about refrigerated trailers if you’re interested in buying one.
History of Cooler Trailers
The first refrigerated trailers were developed during the 1920s and they were initially used to sell ice cream. However, these trailers were limited by the quality of roads at the time, so they were not able to travel really long distances until the Federal Highway Act instituted in 1956, which developed and improved upon national highway systems, creating a network of viable roads for trucks to tow trailers on.
How Refrigerated Trailers Work
Refrigerated trailers are very heavy-duty, weighing over 2000 pounds, thanks to their large refrigeration units. These units are cooled using liquid carbon dioxide and a diesel generator. The units are comprised of a compressor, a condenser, and an evaporator.
The condenser pulls in the gas refrigerant and liquefies it to pull heat out of the trailer. The condenser cools the liquid down even more via a heat-exchange system of tubes that’s connected to the trailer’s exterior. The evaporator releases the cooled liquid using a metering valve that operates at a set temperature.
Most refrigerated trailers are painted white to reflect light, and they are lined with thermoplastics to hold in their cold air. Insulation is a crucial component to prevent the interior of the trailer from heating up, no matter the temperature outside.
