Synthetic Lubricant for refrigeration compressors - Ammonia applications

Product Description

Mobil Gargoyle Arctic SHC NH 68 is a fully synthetic lubricant, specifically designed to lubricate refrigeration compressors in high performance plants using ammonia as the refrigerating fluid. MobilGargoyle Arctic SHC NH 68 is formulated using wax free, synthesized hydrocarbons of polyalphaolefin (PAO) and synthetic Alkylbenzene base oils, which have demonstrated outstanding resistance to thermal/oxidative degradation. Even in the worst operating conditions, Mobil Gargoyle Arctic SHC NH 68 will reduce sludge and deposit formation, hence avoiding or minimizing valve or filter plugging.

 

Features and Benefits

The Gargoyle Arctic SHC brand of lubricants are recognised and appreciated around the world for their innovation and outstanding performance.  Mobil Gargoyle Arctic SHC NH 68 offers exceptional advantages  for ammonia applications  as follows.

 

Features

Advantages and Potential Benefits

Very low pour point

Enables evaporator temperature below conventional mineral naphthenic oils

Solvency

Cleaning effect, especially when switching from mineral oil technology

Wax-free

Excellent low temperature fluidity, no waxy deposits and improved evaporator efficiency

Superior thermal/oxidative and chemical stability

Long oil life compared to mineral lubricant, inducing extended drain intervals and lessroutine maintenance. In turn reduction of maintenance costs

Good compatibility with seals previously used with mineral lubricant

Limited risk of oil leakage

Low volatility

Avoids viscosity build-up, reduced oil consumption

 

Applications

Mobil Gargoyle Arctic SHC NH 68 is recommended for use in screw or reciprocating refrigerationcompressors, in plants using ammonia as refrigerating fluid.Mobil Gargoyle Arctic SHC NH 68 is compatible with mineral lubricants, however, in case ofswitch over, performances or benefits may be minimized, depending on the ratio of mineral oilremaining in the blend. In such case, a specific oil analysis follow up with control of filters should be handled in the following 6 months accordingly.
