Brief Introduction

We believe in: Innovation is our soul and spirit. Top quality is our life. Consumer will need is our God for Hot sale Factory 8kw High Power PTC Electric Liquid Heater. Sincerely hope we have been expanding up together with our customers everywhere in the environment.
This PTC Coolant Heater is an advanced thermal solution designed for electric, hybrid, and fuel cell vehicles.
As a high voltage coolant heater, it serves as the main heat source for cabin temperature regulation and battery thermal management, operating efficiently both when the vehicle is in motion and parked.
By employing PTC technology, this electric vehicle PTC heater instantly converts electrical energy into heat, providing a far faster heating response compared to traditional internal combustion engines. It is ideally suited for warming the cabin, raising battery temperatures to optimal levels, and supporting cold starts in fuel cell systems.
Engineered to meet strict automotive safety standards, this EV coolant heater ensures safe operation in high-voltage environments while also fulfilling environmental requirements for under-hood components. Its compact architecture offers high power density, allowing flexible adaptation to tight installation spaces.
The use of a plastic housing thermally isolates the unit from the chassis, reducing heat loss and improving energy efficiency. Additionally, a redundant sealing design enhances reliability and prevents leakage, contributing to the durability of the thermal management system.
As a versatile and efficient EV heater, this PTC coolant heater replaces conventional engine-dependent heating, delivering immediate heat through effective exchange with the coolant circuit. It is an essential component for modern electric vehicles, supporting Passengers' comfort and functional reliability of high-voltage systems.
We believe in: Innovation is our soul and spirit. Top quality is our life. Consumer will need is our God for EV heaters. As an experienced manufacturer we also accept customized order and we could make it the same as your picture or sample specification. The main goal of our company is to live a satisfactory memory to all the customers, and establish a long term business relationship with buyers and users all over the world.
