Cetus DE

• Cetus DE oils are used for portable and stationary rotary screw, rotary vane, and reciprocating compressors. While specific manufacturer recommendations vary, the ISO 68 grade is most commonly used for rotary compressors, while higher viscosity grade is preferred for reciprocating units. Also suited for the lubrication of anti-friction bearing assemblies operating under high temperature conditions (e.g. in fans, blowers and process pumps).
• Not recommended for use in breathing air compressors.
• These oils can be used in compressors with the following gases: process air, benzene, butadiene, carbon dioxide (dry), carbon monoxide, ethylene, furnace (crack) gas, helium, hydrocarbon gases, hydrogen, inert gases, methane, natural gas, nitrogen, propane, sulfur hexafluoride, and synthesis gas.
  

• Cetus DE oils can be used in contact with the following seals, paints, and plastics: Viton®, High nitrile Buna N®, Teflon®, Epoxy paint, Oil-resistant alkyd, Nylon, Delrin®, Celcon®.
• These oils should not be used with: Neoprene, SBR rubber, Low nitrile Buna N®, Acrylic paint, Lacquer, Polystyrene, PVC, ABS.

Extended service life

Outstanding oxidation stability of the diester base fluid and inhibitor system resists oil breakdown at the elevated temperatures encountered in compressor service, permitting oil drain intervals to be extended beyond those achieved with conventional lubricants. Low sludge forming tendency and a high solvency for deposits that help to keep compressor parts clean even under severe service conditions.

Protection at high and low temperatures 

Diester base fluid ensures an effective oil film to protect loaded parts against wear under both high temperature operating conditions and during low temperature start-up. Higher flash points, fire points, and auto ignition temperatures provide greater margin of safety as compared to conventional mineral oil products. The inhibitor system provides good rust and corrosion protection.

• Matsubara Iron Works Co. Ltd, for use as a reciprocating air compressor lubricant.
• Tanabe Pneumatic Machinery Co. Ltd, for use in their H-series reciprocating marine compressors
  

Cetus DE oils are registered by NSF and are acceptable as lubricants where there is no possibility of food contact (H2) in and around food processing areas. The NSF Nonfood Compounds Registration Program is a continuation of the USDA product approval and listing program, which is based on meeting regulatory requirements of appropriate use, ingredient review and labelling verification.
