Manufacturer's description
Mobil Gargoyle Arctic 68 NH is a high-performance refrigeration oil designed specifically for lubricating reciprocating and screw refrigeration compressors that use ammonia (NH3, R-717) refrigerant. Formulated with high-quality mineral paraffinic technology, it delivers excellent low-temperature performance, low volatility and thermal stability, while its very low miscibility with ammonia limits oil thinning and minimizes oil carry-over. Its low vapour pressure reduces oil consumption and the need for top-ups while preventing fractionation (viscosity increase), and its viscosity is controlled across a wide temperature range to provide the low fluidity needed in the evaporator alongside the higher viscosity required for enhanced equipment protection in the compressor. Mobil Gargoyle Arctic 68 NH is recommended for cylinder and bearing lubrication in conventional reciprocating and screw refrigeration compressors using ammonia, including large industrial compressors in food preparation and freezing, food freezing and cold storage plants, and marine refrigeration applications. Key benefits include reduced oil consumption from low volatility, good oil flow at low temperatures and reliable return from the evaporator thanks to low Brookfield viscosity, surface protection that extends equipment life and lowers repair costs, a high viscosity index for good compressor lubrication across wide operating temperatures, and efficient oil-separator performance from its very low miscibility with NH3.
Applications
- Application considerations: Mobil Gargoyle Arctic 68 NH is recommended for refrigeration systems for cylinder and bearing lubrication in conventional reciprocating and screw refrigeration compressors where ammonia refrigerant is used. This includes: Large industrial reciprocating and screw 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
- Low volatility, helps reducing oil consumption (fewer oil top-ups), limiting oil thinning from fractionation Low Brookfield viscosity contributes to good oil flow at low temperatures and good oil return from evaporator Surface protection for increased equipment life, reduced repair costs High Viscosity Index for good compressor lubrication across wide operating temperatures Refrigerant compatibility contributes to oil separator efficiency (very low miscibility with NH3)
