As automotive systems grow more advanced, maintaining optimal temperature control has become critical — not just for comfort, but for performance and emissions. That’s where PTC (Positive Temperature Coefficient) heaters step in.
What does a PTC heater do in a car?
As automotive systems grow more advanced, maintaining optimal temperature control has become critical — not just for comfort, but for performance and emissions. That’s where PTC (Positive Temperature Coefficient) heaters step in.
KLC’s PTC solutions are compact, self-regulating, and trusted across OEMs.
At KLC, we design custom PTC heating modules for a wide range of automotive thermal management applications:
1. Battery Heating
Electric vehicle (EV) and hybrid batteries lose efficiency in cold climates. PTC heaters ensure ideal battery temperature, improving charging performance, power output, and lifespan.
2. Cabin Heating
Unlike combustion engines, EVs lack waste heat. PTC cabin heaters offer fast, safe, and efficient heating — ideal for driver and passenger comfort in winter.
3. Diesel Filter Heating
Cold starts can lead to diesel particulate filter (DPF) or fuel filter clogging. Integrated PTC heating prevents wax formation and maintains fuel flow in freezing conditions.
4. Blowby Heating
Condensation and oil sludge in blowby systems can reduce engine performance. PTC heaters prevent moisture buildup, ensuring engine cleanliness and efficiency.
5. SCR System Heating
In Selective Catalytic Reduction (SCR) systems, the Diesel Exhaust Fluid (DEF) can freeze below -11°C. PTC heaters keep the DEF tank, lines, and injectors operational, enabling effective NOx reduction.
Why PTC Technology?
–Self-regulating – No risk of overheating
–Compact & energy-efficient – Perfect for tight automotive assemblies
