A refrigerated truck is like a large refrigerator on wheels. At its core, it serves the same purpose as a household refrigerator: Ensuring the freshness of goods as they are transported from point A to point B. These specialized vehicles provide a controlled environment that maintains precise temperatures to preserve food, pharmaceuticals, and other temperature-sensitive products during transit.

Refrigerated van conversions come in 4 types depending on the intended use:
Insulated van conversion:
For transporting non-perishable goods using basic levels of insulation (approx. 50mm thick) in the cargo area that provides minimal temperature control from external and internal temperature variances.
Chiller van conversion:
Using a slightly thicker insulation, the liner is combined with a roof mounted refrigeration unit and evaporator maintains temperatures between 0°C and -8°C (depending on the reefer unit specifications).
Semi-freezer van conversion:
Similar to the chiller van, the semi-freezer van uses thicker wall installation and a higher BTU rated reefer unit that can maintain temperatures down to -15°C.
Full-freezer van conversion:
These vans utilize the thickest van liners (approx. 100mm thick) including insulated side and rear doors, insulated roofs and specially treated floors with a reefer unit that can pull-down temperatures to -20ºC and even -29ºC if required.
The Refrigeration Cycle Explained
The refrigeration cycle in the van is a continuous loop that involves heat absorption and dissipation, ensuring the maintenance of the desired temperature. It starts with the compressor, which compresses the refrigerant gas, increasing its pressure and temperature. This hot, high-pressure gas then flows to the condenser. In the condenser, the gas releases heat to the surroundings, cooling down and transforming into a high-pressure liquid.
This cooled liquid then moves to the evaporator through an expansion valve, which reduces its pressure and temperature. In the evaporator, the low-pressure refrigerant absorbs heat from the van’s interior, effectively cooling the air inside the compartment. This process transforms the refrigerant back into a gas, which is then drawn back into the compressor, completing the cycle.
Throughout this cycle, the refrigerant acts as a medium for carrying heat from inside the van to the outside, maintaining the internal temperature. The precision of this process is critical to ensuring that the goods inside the van are kept at the required temperature.
How Refrigeration Units Work
The refrigeration unit in a reefer truck works on the same basic principles as a household refrigerator but on a larger scale. The unit has a compressor, condenser, expansion valve, and evaporator. Here’s a simple breakdown of how these components work together to keep the cargo cool:
Compressor:
The compressor pressurizes the refrigerant gas, raising its temperature.
Condenser:
The hot, pressurized gas then flows through the condenser coils, releasing heat to the outside air and condensing into a liquid.
Expansion Valve:
The high-pressure liquid refrigerant passes through the expansion valve, which reduces its pressure and cools it down.
Evaporator:
The cold, low-pressure liquid flows through the evaporator coils inside the cargo area. As it absorbs heat from the inside, it evaporates into a gas, and the cycle repeats.
Refrigerated vans range in size and temperature capability, from small vans for local delivery up to large semi-trailers for long-haul transport. Their temperature can be customized based on the goods being transported, from deep freeze (-20°F) up to refrigerated (40°F). This versatility and customizability allow refrigerated vans to suit the needs of nearly any industry or application where temperature control is required.
The range of refrigerated box trucks and vans caters to various cargo sizes and transportation needs. Some of the standard sizes are:
