Carrier Transicold engineless system for refrigerated trucks

Date:

Thanks to the PTO, as soon as the truck engine runs, the hydraulic pump turns on. The mechanical energy of the engine is transformed into a hydraulic flow and then into mechanical energy again, to power the Eco-Drive GenSet. The Eco-Drive is composed of a hydraulic engine coupled to a generator. It is installed on the vehicle chassis.

The hydraulic variable displacement pump ensures a constant flow, whatever the engine speed, providing constant power to the Eco-Drive, which provides a continual cooling capacity of up to 18,000 W to the reefer unit. The refrigerating circuits are fed by fully hermetic scroll compressors.

The system can also be used on trailer trucks, in addition to a classical system where a second engine ensures refrigeration when the truck is parked or when the trailer is unhitched. The system is already commercialised in Europe, and the British supermarket chain Tesco is currently running an 8-year trial on two reefer units.
