Compressor Seals for Vehicle Air Conditioning

Product Description

Passenger vehicles and cargo trucks depend on reliable cooling systems. Auto compressor terminals have to withstand sustained exposure to adverse elements and conditions like cold, heat, moisture, and constant vibrations. Therefore, compressor terminals require extraordinarily careful design and the use of extremely durable materials.

Electric compressors are widely used in environmentally-friendly vehicle applications such as electric vehicles (EVs) and hybrid electric vehicles (HEVs). Normally, gasoline-fueled cars use air-conditioning compressors that are powered by the engine. The electric compressors found in HEVs and EVs, on the other hand, are hermetically sealed and function with their own motor inside. These compressor terminals are used as power transfer terminals.


SCHOTT offers both standard and custom-made compressor seals. Quality insulation is ensured by the use of ceramics and silicon rubber as standard materials to manage substantial insulation areas and challenging environmental conditions. Screws are sometimes used to close the compressor seals, but SCHOTT can also design these seals according to specific customer requests.
