DC5001 - Battery Cooler/Heat-Pump Liquid to Liquid 360Vdc 540Vdc

High-efficiency compact DC powered heat-pump for cooling + heating batteries of electric vehicles such as locomotives, trains, buses, people movers, trucks, POD, defence, Hybrid vehicles (HEV) (PHEV), Electric vehicles (EV) and Fuel cell vehicles (FCV)


Our rugged high performance and low consumption heat pumps are available in
360Vdc (200-420Vdc) or 540Vdc (400-800Vdc) and designed to cool and heat
batteries of battery-powered vehicles under heavy-duty conditions. Maintaining
the battery temperature is mandatory to maximize its life spend and characteristics.


The CANopen connectivity delivers performance in terms of scalability user interface as well as straightforward programming, maintenance and servicing. Ideal for fast and easy customization for vehicles such as Hybrid vehicles (HEV) (PHEV), Electric vehicles (EV) and Fuel cell vehicles (FCV)



The self-contained box consists of a 2-way condenser and evaporator, high efficient slow starting compressor, and an inbuilt electronic control box. The water pump or outdoor heat exchanger is not part of the standard supply.
