The Electrical Decentral Systems – Heating Modules for Seat Heating
● 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.

● Decentral Systems – Heating Modules for Seat Heating
As an innovative development partner for our customers, Espar catem developed the neck-level heating system “Airscarf” (registered trademark of Daimler) for the Mercedes-Benz SLK. In cooperation with our customers, a neck-level heating system was created which for the first time is housed in the seat structure of the backrest between the foam upholstery and the backrest cover.

The innovative neck-level heating system prolongs the open-air season by providing heat and comfort for passengers in convertibles. In winter too, when the roof is closed, it rapidly enhances comfort in addition to the conventional interior heating.

When passengers enter the cold vehicle, warm air flows around the head, shoulders and neck at the push of a button, supplementing and supporting the interior heating.
