Discover the Benefits and Applications for CAMCO RPC-85 & the RPC Series

Product Description

CAMCO® RPC Series

CAMCO® RPC Series is a custom formulated polyolester (POE) synthetic lubricant series suitable for certain refrigeration applications such as with carbon dioxide and hydrocarbon refrigerants. Benefits include excellent lubricity, improved low temperature characteristic, and higher efficiency. Very low volatility can improve oil separation in equipment designed with coalescing elements and improve seal lubrication.

Typical Applications

  • Centrifugal
  • Reciprocating
  • Rotary Vane
  • Screw
  • Scroll

CAMCO® RPC Series is formulated with triaryl phosphates as anti-wear additives.

The special type of polyolesters used in these products has been found to offer less dilution and higher viscosity for better lubricity at higher compressor operating pressures and temperatures. The result is improved lubrication and compression sealing efficiency and better oil return when compared to other types of POE based products.
