Transport Refrigeration Units (TRUs), also called Truck Refrigeration Units, are climate control devices that allow you to heat or cool the trailer when the engine is shut off. TRUs typically run off the main diesel engine while running down the road. However, when the trailer is parked, loading, or unloading, the TRU can continue to be powered by the main engine or run off a separate standby engine. These are typically diesel engines and emissions can have a direct impact on the air quality surrounding drivers and workers while the trucks are stationary.

Transport Refrigeration Units are now available in both Electric Standby units (ES-TRUs) and All-Electric options. These still use the truck’s main engine to drive the compressor while in transit, but allows the truck to operate from electric shore power while parked, loading, or unloading. All-electric TRUs runs completely off of the electric shore power, used for on-site storage or overflow storage, whereas an ESTRU, also referred to as a hybrid TRU, can be used on the road for diesel and electric shore power while parked.

Electric Standby or all-electric TRUs reduce or eliminate the amount of diesel fuel used and significantly reduce or eliminate carbon emissions. ES-TRUs and all-electric TRUs use fewer parts and require less maintenance than their diesel counterparts. Eliminating the heat produced by a standby diesel engine results in a longer equipment lifecycle. ES and all-electric TRUs also provide significant fuel savings and reduce noise at the facilities where parked.
