SUMMIT DSL LUBRICANT
Summit DSL synthetic lubricants are unique combinations of quality diester base stocks and the latest additive technology.

Summit provides a wide range of DSL lubricants that cover applications for rotary vane, rotary screw, and all ages and design types of reciprocating compressor.

Summit DSL lubricants are especially noted for the following benefits:

  • Low temperature fluidity
  • Better thermal conductivity - reduces operating temperature
  • Reduced friction - approximately 20% lower coefficient of friction
  • High temperature thermal stability will not disassociate under thermal stress
  • Greater resistance to mechanical stress will not shear under heavy loads or extreme stress
  • Reduced metal-to-metal wear-polar properties provided better metal wetting
  • Better demulsibility characteristics - moisture separates readily, providing better rust and corrosion protection
  • More energy efficiency

COMPATIBILITY

The following materials are compatible for use with DSL lubricants: Epoxy Paint, Celcon, Viton, High Nitrile Rubber (Buna N, NBR - greater than 36% Acrylonitrile), Medium Nitrile Rubber (Buna N, NBR 30-36% Acrylonitrile), Teflon, Oil Resistant Alkyd, and Nylon.

Summit DSL lubricants are not compatible with some elastomers used in compressors and pumps including some paint used in crankcases. Please contact us for specific recommendations.
