ROYCO 889 is a synthetic-based lubricant formulated for use in gas compression applications that require wide operating temperature ranges and minimum interaction between the lubricant and the process gas.
ROYCO 889 is intended for the lubrication of flooded rotary screw and vane-type compressors processing natural gas, carbon dioxide, or other hydrocarbon gases. ROYCO 889 may also be used as a cylinder lubricant for reciprocating compressors processing natural gas, carbon dioxide and other gases that require chemical resistance in an ISO 150 viscosity grade.
COMPATIBILITY
Recommended: Acetone, Alcohol, Asbestos, Butyl Dioxtol, Chlorinated Solvents, Glycol Ether, Neoprene, Epoxy Paint, Silicone Rubber, Toluene, Torlon (AMOCO), Vespal (DuPont), and Viton (DuPont).Questionable: Ethylene Glycol, Triethanolamine, and Water.Not Recommended: Gasoline, Glycerol, Heptane, Kerosene, Leather, Methanol, and Oil-based paint.
Resists wash off by hydrocarbon gases and liquidsResists absorption into the gas phase and carry-over of the lubricant downstreamMinimizes dilution effects due to insolubility of the lubricant with hydrocarbonsHigher film-strength that traditional lubricantsProtects against corrosionFully compatible with most compressor component materials, including: seals, gaskets, hoses, etc.
