Description
7KW Automotive Electric PTC Coolant Heater
Products Description
This PTC electric heater is suitable for electric/hybrid/fuel cell vehicles and mainly serves as the main heat source for temperature regulation inside the vehicle. The PTC electric heater is suitable for both vehicle driving mode and parking mode.
During the heating process, electrical energy is effectively converted into thermal energy by PTC components, so this product has a faster heating effect than internal combustion engines. At the same time, it can also be used for temperature regulation of batteries (heating to working temperature) and fuel cell start-up loads.

This PTC electric heater adopts PTC technology to meet the safety requirements of passenger cars for high voltage. In addition, it can also meet the relevant environmental requirements of components in the engine compartment.
The purpose of PTC electric heaters in application is to replace the engine block as the main source of heat. It heats the PTC heating component by supplying power to the PTC heating group, and heats the medium in the heating system circulation pipelinethrough heat exchange.
