Important Note:

Remember that trailer refrigeration is only part of a successful outcome and although it is important it is also critical to put in on a properly insulated box especially if you want to maximize efficiency or need to keep your product frozen. We discourage folks every day from installing trailer refrigeration on cargo trailers that have been retrofitted. Why, because their main structure is made of wood and the question is not am I going to get mold or mildew but when am I going to get it.

To Get The Best Out Of Your Refrigeration Unit In A Nutshell


small refrigerated trailer 2How Does a Small Refrigerated Trailer Work?

A small refrigerated trailer, often referred to as a ‘reefer trailer’, is a specialized transportation unit designed to maintain perishable goods at specific temperatures during transit. Here’s a breakdown of how it operates:

  1. Insulation: The trailer walls, floor, and roof are lined with high-quality insulation, usually made of foam or other insulating materials. This ensures minimal thermal exchange between the interior and exterior environments.
  2. Refrigeration Unit: At the front of the trailer, you’ll find the refrigeration unit. This is the heart of the system. It’s powered by a combination of diesel fuel and electricity.
  3. Thermostat Control: Within the trailer, there’s a thermostat which constantly monitors the interior temperature. When the temperature rises above the set point, it triggers the refrigeration unit to start cooling.
  4. Cooling Process: The refrigeration unit works on the principles of the vapor-compression refrigeration cycle. In simple terms, a refrigerant gas is compressed, causing it to release heat and become a high-pressure liquid. This liquid then flows through a series of coils inside the trailer, where it evaporates and absorbs heat from the trailer’s interior, thereby cooling the space. The gas is then compressed again, and the cycle continues.
  5. Air Circulation: To ensure uniform temperature throughout the trailer, fans are used to circulate the cold air. This prevents ‘hot spots’ which could jeopardize the quality of the stored goods.
  6. Sealed Environment: The doors of the trailer form a tight seal when closed. This helps in maintaining the desired temperature and prevents the infiltration of outside air.
  7. Power Source: While some trailers are equipped to run off their own batteries or the truck’s electrical system, others might have a standalone generator for the refrigeration unit.

In essence, a small refrigerated trailer is an integrated system of insulation, refrigeration, and circulation, all working in tandem to ensure perishable goods are kept at optimal temperatures during transportation.
