Cooling Fluid Function

Cooling fluid plays a vital role in compressor function.  It is directly injected into the compression chamber providing maximum cooling efficiency and low discharge temperatures. The fluid also serves to flush out contaminants from the compressed air, lubricate the rotors and bearings, and it creates a seal between the rotors and the airend casing.

Sigma Premium Fluids are specially formulated and offer many additional benefits. 

• Excellent service life up to 9,000 hours
• Extended bearing life with good wear protection
• Superior cleaning characteristics prevent deposits
• High viscosity index offers outstanding protection and remains stable even under extreme operating conditions
• Excellent demulsifying properties allow easy condensate separation
