Manufacturer's description

Mobil SHC Gargoyle 80 POE is a high-performance refrigeration oil formulated with Polyol Ester (POE) technology, designed specifically for lubricating refrigeration compressors that use carbon dioxide (CO2, R-744) refrigerant in miscible applications. It delivers outstanding lubricity, wear protection and chemical and thermal stability, with miscibility and well-defined viscosity/temperature/pressure behavior that ensures adequate oil film thickness even at the high operating pressures and temperatures seen in piston compressors using CO2. Its naturally high, shear-stable viscosity index and good low-temperature fluidity provide additional benefits in severe service, including reduced shaft leakage and the potential for improved evaporator efficiency; the resulting oil film thickness helps maintain shaft sealing and reduces bearing fatigue, while a low traction coefficient supports improved system efficiency and lower power consumption. The product is recommended for CO2 refrigeration systems including large industrial reciprocating compressors used in food preparation and freezing, industrial cold storage plants, and marine refrigeration. As it is hygroscopic, packages should be kept tightly closed and moisture ingress avoided during handling.

Applications

• Hygroscopic — care must be taken to avoid moisture absorption during handling; packages should be tightly closed when not in use, and small packaging is preferred.
• Should not be transferred to plastic containers that may allow moisture ingress.
• Recommended for refrigeration systems using carbon dioxide refrigerant.
• Large industrial reciprocating refrigeration compressors used in the food industry for food preparation and freezing.
• Industrial applications such as food freezing and cold storage plants.
• Marine refrigeration applications.

Performance & benefits

• High oil film thickness in the presence of refrigerant helps maintain excellent shaft sealing, reducing bearing fatigue and unscheduled downtime.
• Appropriate miscibility and VPT relationships with carbon dioxide help reduce operating oil crankcase temperature, resulting in higher in-service viscosity and a thicker oil film for better lubricity and wear protection.
• Excellent wear protection contributes to potential extended compressor life.
• High viscosity index and excellent low-temperature fluidity help improve evaporator efficiency.
• Low traction coefficient provides potential for improved system efficiency and reduced power consumption.
