How to use PTC Auxiliary Heater in Automotive Industry
In the automotive industry, PTC (Positive Temperature Coefficient) air heaters have become a crucial component in modern vehicle heating systems. Unlike traditional resistance wire heaters, PTC air heaters are self-regulating, energy-efficient, and provide rapid heating without the risk of overheating. These heaters are widely used in electric vehicles (EVs), hybrid cars, diesel vehicles, and fuel-powered vehicles to ensure effective cabin heating, defrosting, and battery thermal management.
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of auxiliary heater for air ptc in China, also supports custom service. Welcome to wholesale high quality auxiliary heater for air ptc at competitive price from our factory.
PTC (Positive Temperature Coefficient) air heaters are now an important part of how cars are heated. They are different from traditional resistance wire heaters because they can automatically adjust the heat, use less energy and get the car warm quickly without the risk of overheating.
These heaters are used in many types of vehicles, including electric vehicles (EVs), hybrid cars, diesel vehicles, and fuel-powered vehicles. They help to keep the cabin warm, defrosting the windows, and manage the battery temperature.

Automatic Temperature Control – The PTC Auxiliary Heater adjusts its power output as the temperature rises, to stop it from overheating.
It also prevents overheating and thermal runaway by decreasing the heating power when it reaches its set temperature.
Scalable Power Output – Power levels range from 200W to 3,000W, depending on the application.
High-Quality Ceramic PTC Auxiliary Elements – Ensures durability, corrosion resistance, and stable performance.
Resistant to Wear & Tear – Designed for continuous heating cycles in automotive applications.
HVAC System Integration – Works seamlessly with electric vehicle (EV) and hybrid car climate control systems.
PWM & CAN Bus Control – Supports Pulse Width Modulation (PWM) and CAN Bus for smart energy management and system integration.
