Mobil Gargoyle Arctics SHC 230
The information contained in this Product Bulletin is out of date.
Mobil Gargoyle Arctic SHC 200 Series are fully synthetic high performance lubricants specifically designed for use in refrigeration compressors and heat pumps. Lubricants are formulated from wax-free synthetic hydrocarbon polyalphaolefin (PAO) fluids with superior resistance to thermal and oxidation degradation. Thanks to their naturally high shear resistant viscosity index and easy fluidity at low temperatures, they are able to perform in difficult conditions beyond the capacity of conventional mineral oils. Since these oils have low solubility and miscibility in refrigerant gases, this
As a result, it creates a thicker film in the environment with pressurized refrigerant gas and reduces shaft seal leakage. Mobil Gargoyle Arctic SHC 200 Series oils reduce friction and frictional losses and increase the operating efficiency of the cooling system. These oils are recommended for the lubrication of refrigeration compressors operating at very high temperatures and for systems with very low evaporator temperatures. These are ammonia (NH3) and carbon dioxide
It is suitable for refrigeration compressors using refrigerants such as (CO2) and also excellent results have been achieved with CFC refrigerants such as R-12. They are compatible with all refrigerants except sulfur dioxide and have been found to be very successful, especially in systems using ammonia (NH3) as refrigerant. Mobil Gargoyle Arctic SHC 200 Series is fully miscible with conventional mineral oils, but this may reduce the superior performance properties of Mobil synthetic.
Features and Benefits
Mobil SHC Series oils are globally recognized and accepted lubricants for their innovative and superior performance. The molecular design of PAO synthetic products, led by our scientists, is a testament to Mobil's continued commitment to using advanced technology to create unique lubricant products. Our work with equipment manufacturers confirms our knowledge of lab tests on the unmatched performance of Mobil Gargoyle Arctic SHC 200 Series lubricants. Industrial machinery
Collaborative studies with manufacturers have also shown that excellent fluidity at low temperatures, as well as resistance to viscosity loss due to mixing of refrigerant gas under pressure, excellent thickness oil film and shaft sealing.
Mobil Gargoyle Arctic SHC 200 Series oils provide thermal / oxidation resistance, a critical property for high temperature applications, due to the nature of the PAO base oils used in them. The narrow range of molecular distribution of PAO base oils also minimizes the evaporation and transport of the oil. Mobil Gargoyle Arctic SHC 200 Series oils provide the following features and potential benefits:
Features Advantages and Potential Benefits
Better shaft sealing, lower bearing fatigue and less, as well as longer compressor life
High oil film thickness in the refrigerant environment provides anti-wear feature to the compressor that will provide unscheduled stopping opportunities.
Features Advantages and Potential Benefits
Long oil life, extended oil change intervals and more
Provides a small number of periodic maintenance
Excellent thermal / oxidation and chemical stability
Provides longer filter life and lower shaft sealing due to low lacquer and deposit formation
