Freudenberg Sealing Technologies has developed a new sealing system for busbar sealing in vehicle air-conditioning compressors. This elastomer-based solution withstands test pressures of over 100 bar in leak tests and offers a cost-efficient alternative to conventional glass seals. Designed for CO₂ compressors (R744), it also works well with other refrigerants.
European regulations on fluorinated greenhouse gases are accelerating a transformation in the automotive industry: The fluorinated refrigerants R134a and R1234yf are gradually being replaced by alternatives. The natural refrigerants R744 (CO₂) and R290 (propane) are considered particularly viable for the future. However, using CO₂ in refrigerant compressors involves considerable technical
