refrigerator Oils Mobil Gargoyle Arctic SHC 200 series

Product Description
Gargoyle Arctic SHC 200 Series are fully synthetic, supreme performance lubricants, specifically designed for
use in refrigeration compressors and heat pumps used in marine, commercial and industrial applications. They
are formulated from wax-free, synthesized hydrocarbon polyalphaolefin (PAO) fluids, which have outstanding
resistance to thermal/oxidative degradation. With their naturally high shear stable viscosity index and low
temperature fluidity, they are able to perform in severe service conditions that are beyond the capabilities of
conventional mineral oils. Their solubility and miscibility with refrigerants is low, resulting in higher film thickness
in the presence of refrigerants under pressure and reduced shaft seal leakage. Their stability and low volatility
eliminates "light end stripping" which can occur with conventional mineral oils. Gargoyle Arctic SHC 200 Series
lubricants help reduce frictional losses and improve machine operating efficiency.
Gargoyle Arctic SHC 226E and 230 lubricants are recommended for the lubrication of refrigeration compressors
operating at very high temperatures, and for systems with very low evaporator temperatures. They are suitable
for compressor systems using refrigerants such as ammonia, carbon dioxide and HCFCs such as R-22. They
have also enjoyed excellent experience with CFC refrigerants such as R-12. They are compatible with all
refrigerants except sulfur dioxide and have been particularly successful with systems using ammonia as the
refrigerant. Gargoyle Arctic SHC 226E and 230 are fully miscible with conventional mineral oils, but admixture
may detract from the superior performance properties of the Mobil synthetic product.
Features and Benefits
The Mobil SHC brand of lubricants are recognised and appreciated around the world for their innovation and
outstanding performance. These molecular design PAO synthetic products, pioneered by ExxonMobil research
scientists, symbolize the continuing commitment to using advanced technology to provide outstanding lubricant
products.
Work with equipment builders has helped confirm the results from ExxxonMobil laboratory tests showing the
exceptional performance of the Gargoyle Arctic SHC 226E and 230 lubricants. Not least among the benefits
shown in work with OEMs is the superb low temperature capability providing excellent fluidity at low temperatures,
as well as the resistance to viscosity loss due to refrigerant absorption under pressure providing excellent bearing
film thicknes and shaft sealing properties.
By its nature, the PAO base oil used in Gargoyle Arctic SHC 200 Series oils provides exceptional thermal/oxidative
resistance critical for high temperature applications. The narrow molecular weight distribution of the PAO base
stocks also minimizes volatility and reduces oil carryover.
Gargoyle Arctic SHC 226E and 230 oils offer the following features and potential benefits:
Features Advantages and Potential Benefits
Improved compressor antiwear protection for extended
compressor life as well as better shaft sealing, reduced
bearing fatigue and less unscheduled downtime.
