Typical characteristics

Manufacturer's description

Mobil Gargoyle Arctic SHC 200 Series are fully synthetic, superior-performance lubricants specifically designed for refrigeration compressors and heat pumps. Formulated from wax-free, synthesized hydrocarbon polyalphaolefin (PAO) fluids, they offer outstanding resistance to thermal and oxidative degradation, with naturally high shear-stable viscosity index and low-temperature fluidity that outperform many conventional mineral oils. Their low solubility and miscibility with common refrigerants gives higher film thickness under pressure, helping to reduce shaft seal leakage, while their stability and low volatility reduce the light-end stripping seen with mineral oils. Recommended for refrigeration compressors operating at very high temperatures and systems with very low evaporator temperatures, the series suits compressor systems using ammonia and carbon dioxide, with low miscibility making it particularly suited to CO2 screw compressors; it is compatible with most common refrigerants except sulphur dioxide. Typical applications include commercial, industrial, heat pump and marine refrigeration systems, for both reciprocating and rotary compressor designs. The series is fully miscible with conventional mineral refrigeration oils, though mixing will reduce the synthetic product's outstanding performance. Mobil Gargoyle Arctic SHC 224 is NSF H1 and NSF HT1 registered and meets FDA 21 CFR 178.3570. Its typical viscosity is 29.0 mm²/s at 40 °C and 5.6 mm²/s at 100 °C, with a viscosity index of 132, a pour point of <-54 °C and a Cleveland open cup flash point of 230 °C. Like the rest of the series, it delivers high oil film thickness for extended compressor life and better shaft sealing, excellent thermal/oxidative/chemical stability for long oil life, low volatility for consistent viscosity, wax-free composition for good low-temperature fluidity, low traction coefficient and strong seal compatibility.

Applications

• Fully synthetic lubricants specifically designed for refrigeration compressors and heat pumps.
• Commercial, industrial and heat-pump applications, and marine refrigeration systems.
• Commercial, industrial and residential heat-pump applications.
• Recommended for both reciprocating and rotary compressor designs.
• Recommended for use with ammonia and carbon dioxide refrigerants.
• Compatible with mineral-oil products, but mixing will reduce performance; systems should be thoroughly flushed and cleaned when converting from a mineral product. For R22 refrigerant, always follow the refrigeration-unit supplier's guidance to ensure efficient oil/refrigerant separation.

Performance & benefits

• High oil-film thickness in the presence of refrigerant improves compressor protection for extended compressor life, gives better shaft sealing, reduces bearing fatigue and reduces unscheduled downtime.
• Excellent thermal/oxidative and chemical stability give long oil life, less frequent drain intervals and routine maintenance, and reduced lacquer and deposit formation.
• Low volatility keeps viscosity consistent, with reduced oil consumption.
• High viscosity index and a wax-free composition give excellent low-temperature fluidity, no waxy deposits and improved evaporator efficiency.
• Low traction coefficient offers the potential for improved system efficiency and reduced power consumption.
• Seal compatibility gives long seal life and reduced shaft-seal leakage.
