The Electrical PTC Air Heater Elements for Decentral Applications
● Heating comfort for modern vehicle concepts
Modern, fuel-efficient vehicle engines provide too little waste heat to ensure a sufficient and comfortable temperature in the passenger compartment. With additional electrical air and water heaters (PTC heaters), Espar catem offers an effective solution to this challenge.

The PTC heater elements can be adapted without difficulty to customized applications and can also be used decentrally in the vehicle, for example for targeted neck-level heating. This know-how is already operational in more than 25 million vehicles around the globe.

With high-voltage applications up to 500 V, Espar catem is already developing mass-production-ready PTC heaters. They can be installed in very little space in future vehicle generations with hybrid, electric and fuel cell drives. These PTC heater elements cover an output range of up to 7 kW and can be adapted to the typical voltage ranges, providing highly efficient heating even in new vehicle concepts.

● PTC Air Heater Elements for Decentral Applications
When developing future vehicle generations, enhancing comfort inside the vehicle will be of central importance. Air-conditioning in the vehicle requires rapid warming of the interior on demand. It is clear that decentral warming of the interior yields advantages here, especially for vehicles with a large interior such as SUVs, vans, station wagons and transporters.

Advantages:
● Using several small PTC air heaters, the conditions can be set individually for every area within the vehicle.
● Heat is provided where it is needed.

The decentral heating elements are based on the same technology as all our PTC air heaters, which have proven their effectiveness in millions of applications.
