CARRIER TRANSICOLD is hoping that a new refrigeration unit for vans will replicate the firm’s success in the reefer trailer market, targeting supermarket homedelivery van fleets.
Unlike units made by rivals Hubbard and GAH, Carrier’s new Pulsor is not a conventional direct-drive design, where the compressor is mechanically driven from the vehicle’s engine. Instead, Pulsor’s compressor is electrically driven, taking power from an enginemounted generator.
The Pulsor range of six models, including multi temperature versions, is mainly for vans from 2.8tonne GVW up to trucks of around 7.5-tonnes GVW.
Carrier claims Pulsor offers several advantages over direct-drive models, including its own, which will still be offered alongside the Pulsor.
“The road compressor on direct-drive units is the weakest component and makes these the most unreliable of all fridge units,” says Carrier Transicold UK operations director Scott Dargan. He also forecasts that Pulsor’s annual refrigerant leakage will average just 2.5%, cutting typical CO2 emissions by about 75% compared with a direct-drive unit. Its temperature pull-down is reckoned to be twice as fast. Fuel consumption during pull-down is claimed to be 20% lower than its rivals’. Pulsor will cost more than direct-drive models, but Dargan says this is offset by better reliability.
