R744 Compressor Shaft Seal

Description

The German expert for dynamic seals has designed a compressor shaft seal for high-pressure R744 vehicle air conditioning, ensuring lowest leakage rates while driving and during long standstill times.

Advantages

• Leak-tight sealing of CO₂ compressor shafts
• passed all necessary endurance and leakage tests with excellent results
• Lowest levels of static leakage in new condition and during long standstill times: even at long standstill times of 700 hours the average leakage from an R744 compressor equipped with KACO’s shaft seal is less than 5 g/year (VDA requirement: 15 g/year)
• Lowest level of static leakage after usage during long standstill times
• Lowest level of dynamic leakage at all relevant operation conditions 
• High-pressure resistance: resistant to pressures of up to 90 bar
• High temperature resistance: reliable operation at temperatures of 54°C
• Reliability: at all operating conditions the shaft seal works reliably
• Legal compliance: ensures that CO₂ compressors already now comply with international leakage requirements and current technical specifications
• Long-term durability
• Low friction loss 
• Future-proof: suitable for CO₂ MAC used in heat pump mode and especially suited for electric and hybrid vehicles
