Third Generation PTC Coolant heater 7KW

PTC coolant heaters provide heat to cabin of new energy vehicles and meet the standards for safe defrosting and defogging. It can also provide heat to other parts in the vehicle that require temperature regulation, such as batteries

 Specialty

           provide heating with electrically heating of coolant

           fixed in water circulation system

           soft warm wind and controllable temperature

           Gear control is used to adjust the power

             It has the function of short-term heat storage

 

           circulation in vehicle, support battery thermal management
