Description
Castrol Aircol PG 185 is a high-performance synthetic gas compressor oil based on poly-alkylene glycol, for the lubrication of compressors handling hydrocarbon and chemical gases.
- Pack size: 20 L canister
- Also available in: 208 L drum
Applications
- Working sumps of both rotary and reciprocating compressors where the lubricant is in continuous contact with the gas being compressed
- Liquified natural gases (methane, ethane)
- Liquified petroleum gases (propane, butane)
- Hydrocarbon chemical gases (ethylene, propylene, butylene)
- Chemical gases (ammonia, vinyl chloride, butadiene)
Specifications & Approvals
- Meets the requirements of Sulzer Burckhardt A.G., Winterthur for use in K-type gas cargo compressors
Key Properties & Benefits
- Low solvency with hydrocarbon and chemical gases, thus avoiding significant fall in viscosity and lubricant performance
- Totally synthetic—does not break down or polymerise to form gums, resins or carbon
- Very high viscosity index supports extreme temperature operations
- Wide range of applications including LPG, LNG hydrocarbon and chemical gases
