Reefer components

Reefers remove heat generated by the “respiration” of products, thus keeping temperatures stable. They also control humidity to maintain conditions favourable to the cargo. But how does a reefer do this? Let’s look at the reefer components that fulfil these key functions:

  1. Genset: A genset, or generator set, is the reefer’s power source. It is usually dual-powered, which means it runs both on fuel (diesel, petrol and gas mostly) and electricity. This ensures it can tap the power unit of a ship or operate on fuel while on a truck. The genset can be clipped to the side of the container (clip-on genset) or mounted on the chassis of the container from the bottom (underslung genset).
  2. Humidity control: The relative humidity of air in a reefer is critical to the safe transportation of cargo. (Relative humidity is defined as “the amount of water vapour in air expressed as a percentage of the amount needed for saturation at the same temperature”.) Dry air can cause excessive water loss in fruits and vegetables while moisture in the air can cause mold and bacteria. A reefer’s humidity control mechanism maintains optimum humidity conditions for goods such as pharmaceuticals and electronics. It ensures dry packing and prevents fungi and rotting in the case of consumables. A reefer has a dehumidification range of 60% to 95% maximum relative humidity in the chilled temperature range.
  3. Temperature control: Reefers are either water-cooled or air-cooled, though water-coolant systems are dwindling because they are expensive. Air cooler fans, either propeller or centrifugal type, remove dissipated heat from the refrigeration unit. A compressor, powered by a small engine, draws in refrigerant gases and compresses and liquefies them. This releases heat in the surrounding air. The air flows into a condenser and then into an evaporator, which drains the heat outside.
  4. GPS chip: A reefer comes equipped with a GPS chip to ensure no package is lost in transit. Typically, containers enter multiple ports and use several transportation modes before they arrive at their final destination. Cargo security is paramount. And the GPS chip provides the location and temperature status of each container.
