Historically, hydrocarbon, chemical process and inert industrial gas compressors used conventional mineral oil based lubricants. However, these lubricants often failed when they encountered temperature extremes, extreme dilution or chemically hostile gases.
CPI performance lubricants offer many advantages over conventional mineral oils. Some of the advantages include excellent chemical inertness, high viscosity index, low pour point, good hydrolytic stability and complete demulsibility. They also offer good natural lubricity, excellent thermal stability, resistance to hydrocarbon dilution, low volatility and both elastomers and metal compatibility.
CPI's applications engineers use computer modelling to determine the potential lubricant dilution. Based on the dilution, experience with similar applications, and the compressor manufacturer's requirements, the engineer selects the proper lubricant.
