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 |
Application
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.
