High Film Thickness with Refrigerant

Low miscibility and solubility with ammonia and CO₂ refrigerants results in higher oil film thickness in the presence of refrigerant under pressure — improving compressor bearing protection, reducing shaft seal leakage and extending compressor life versus conventional mineral refrigeration oils.

Outstanding Thermal & Oxidative Stability

PAO base stock provides exceptional resistance to thermal and oxidative degradation — delivering long oil life, reduced frequency of drain intervals and reduced lacquer and deposit formation in high-discharge-temperature compressor applications.

Excellent Low-Temperature Fluidity

Wax-free PAO base stock with VI 136 and pour point -45°C provides excellent low-temperature fluidity and no waxy deposits — ensuring reliable oil circulation and lubrication in very low evaporator temperature systems without blocking oil lines, strainers or expansion devices.

Low Volatility — Reduced Light-End Stripping

The low volatility of the PAO base stock reduces the "light end stripping" effect that causes viscosity increase and oil consumption in conventional mineral oils operating at high discharge temperatures — maintaining consistent viscosity throughout the service interval.

Improved System Efficiency

Low traction coefficient of the PAO base stock offers potential for improved system efficiency and reduced power consumption in refrigeration compressor applications — contributing to improved evaporator efficiency through better separation characteristics.

Seal Compatibility

Good compatibility with seal materials used in refrigeration compressors — long seal life and reduced shaft seal leakage. Verify seal compatibility with your compressor OEM before converting from mineral oil, particularly where elastomer types are non-standard.

Ammonia Refrigeration Compressors

Both reciprocating and rotary screw compressor designs using ammonia (NH₃) refrigerant — the primary application where the low miscibility of SHC 226E with ammonia provides superior film thickness and shaft sealing versus mineral refrigeration oils that dissolve more readily in ammonia.

CO₂ Screw Compressors

Screw compressors using carbon dioxide (CO₂) refrigerant — where the low miscibility of Mobil Gargoyle Arctic SHC 200 Series with CO₂ makes it a suitable choice for CO₂ screw compressor lubrication in industrial, commercial and marine refrigeration systems.

Heat Pump Applications

Commercial, industrial and residential heat pump applications — where the combination of high discharge temperature performance, low refrigerant miscibility and long oil life provides superior service life versus mineral heat pump compressor oils.

Marine Refrigeration Systems

Commercial and marine refrigeration systems using ammonia or CO₂ refrigerant — including fishing vessel and cargo vessel refrigeration, cold store plant and marine heat pump systems where extended service intervals and thermal stability are required.

NSF H1 Registered

Registered for incidental food contact — suitable for use in food and beverage refrigeration compressors where incidental contact with food is possible

FDA 21 CFR 178.3570

Meets FDA requirements for lubricants used in food processing environments where incidental food contact may occur

Ammonia (NH₃) Compatible

Particularly successful in ammonia refrigeration systems — low miscibility maintains film thickness under pressure

CO₂ Screw Compressor Suitable

Low miscibility with CO₂ makes it a suitable choice for screw compressors using carbon dioxide refrigerant

Reciprocating & Rotary Compressors

Recommended for both reciprocating and rotary screw compressor designs in refrigeration and heat pump service

Marine Refrigeration

Suitable for commercial, industrial and marine refrigeration systems — fishing and cargo vessel cold stores
