Refrigeration Oils

Product Description

The Mobil Gargoyle Arctic SHC™ 200 Series are fully synthetic, superior performance lubricants, specifically designed for use in refrigeration compressors ａnd heat pumps. They are formulated from wax-free, synthesised hydrocarbon polyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. With their naturally high shear stable viscosity indexes ａnd low temperature fluidity, they are able to perform in severe service conditions that are beyond the capabilities of many conventional mineral oils. Their solubility ａnd miscibility with commonly used refrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure. This can help to reduce shaft seal leakage. Their stability ａnd low volatility characteristics reduces the  "light end stripping" which can occur with conventional mineral oils. Mobil Gargoyle Arctic SHC 200 Series lubricants may help reduce frictional losses ａnd improve machine operating efficiencies.

Mobil Gargoyle Arctic SHC 200 Series 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 ａnd carbon dioxide. Their  low miscibility with carbon dioxide makes them a suitable choice for screw compressors using carbon dioxide. They are compatible with most common refrigerants, except sulphur dioxide, ａnd have been particularly successful in systems using ammonia as the refrigerant. Mobil Gargoyle Arctic SHC 200 Series are fully miscible with most conventional mineral refrigeration oils. Any mixture with mineral oils may detract from the outstanding performance properties of the Mobil synthetic product.

Features ａnd Benefits

The Mobil Gargoyle Arctic SHC brand of lubricants are recognised ａnd appreciated for their innovation ａnd outstanding performance.

Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobil Gargoyle Arctic SHC 200 Series 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, along with providing excellent bearing film thickness ａnd shaft sealing properties. 

By its nature, the PAO base stock  used in Mobil 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 can help to reduce oil carryover. Mobil Gargoyle Arctic SHC 200 Series oils offer the following features ａnd potential benefits:

Applications

Mobil Gargoyle Arctic SHC 200 Series are fully synthetic lubricants specifically designed for use in refrigeration compressors ａnd heat pumps.

Application Considerations: While Mobil Gargoyle Arctic SHC 200 Series are compatible with mineral oil products, a mixture will detract from their performance.  Systems should be thoroughly flushed ａnd cleaned when replacing a mineral product with a Mobil Gargoyle Arctic SHC 200 Series product. In the case of R22 refrigerants, guidance from the supplier of the refrigeration unit must always be sought to ensure compressor operation is suitable for efficient separation of the oil ａnd refrigerant.

Typical applications are indicated below:

• Commercial, industrial, 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 the following refrigerants: Ammonia ａnd Carbon Dioxide
