COMPRESSORS: C-comp CLUTCH OPERATED
• Multi-disc clutch integrated into the Compressor
• Clutch actuation is pneumatic as with today’s Power Reduction system
• Fail safe operation (pressure needed to activate the clutch)
• First business with a major OE awarded, SOP early 2011
Huge improvement of fuel economy in off load compared to:
Line unloader (up to € 1,000 annually for 1-shift operation)
Power Reduction system (over € 210 annually for 1-shift operation)
Lower overall noise emission as compressor is fully disengaged from engine during off load
Cleaner air due to lower oil carry-over and oil degradation, driving lower maintenance costs
The Compressor Add-on Providing Highest Off-Load Fuel Saving
