Refrigeration Compressor Oil - Petro Canada

- Lower concentrations of compressor fluid in the ammonia also help to maintain refrigerant purity, improving system efficiency and performance

- Excellent thermal and oxidative stability extends fluid life, reducing maintenance costs and downtime

- Excellent resistance to oxidative and thermal breakdown guards against oil thickening, deposits and sludge formation

- Helps to keep the compressor, heat exchanger and expansion valves operating at their design efficiency and per formance standards

- Extends fluid life, even in the presence of impurities in the ammonia refrigerant, saving on downtime and change-out costs.


Additional Performance Benefits

- High viscosity index ensures proper lubrication and protection from wear over a wide range of operating temperatures

- High flash point ensures safe operation at elevated temperatures

- REFLO A provides some rust and corrosion resistance to help protect components from attack by moisture and chemical impurities

Applications

REFLO A is formulated to lubricate ammonia refrigeration compressors used in large commercial operations such as cold stores, food processing plants, marine systems and ice arenas. REFLO A is also used in manufacturing industries that require low temperature control, such as pharmaceuticals and microelectronics. REFL0 A can be used in ammonia refrigeration systems where evaporator temperatures are greater than -42°C/-44°F. REFLO A is compatible with mineral oils such as solvent refined (SR) paraffinics and naphthenics, and may be used to top-up systems using these types of fluids. The full benefits of REFLO A will not be realized without a complete fluid change-out. Most OEM's use Neoprene® (Polychloroprene), HSN (Highly Saturated Nitrile) or BUNA N (Nitrile) and REFLO A fluids are fully compatible with these types of materials. However, when a compressor is converted from one oil formulation or type to another, there is always a risk of seal swell or shrinkage. Unlike naphthenic fluids or fluids derived from aromatic chemicals such as alkyl benzenes, REFLO A fluids cause little or no seal swell. Although tightening flanges can sometimes correct minor leaks, we advise that whenever possible, new seals should be retrofitted during the oil conversion. Follow the OEM's seal recommendation for Hydrotreated Paraffinic oil (ie. Mycom W series reciprocating compressors should use HSN or Neoprene® only).
