Petro-Canada REFLO 68A Refrigeration Compressor Fluid

Product Description

Petro-Canada’s REFLO A is an ammonia refrigeration compressor fluid used in industrial refrigeration systems. REFLO A is formulated to outperform solvent refined paraffinic and naphthenic refrigerant oils by helping to extend service life thereby helping to reduce operating costs.

REFLO A’s performance results from more than 25 years formulating experience. Using the HT purity process, Petro-Canada produces 99.9% pure base oils – among the purest in the world. Virtually free of impurities that can hinder fluid performance; these crystal clear base oils are fortified with specialty selected additives. The result is a refrigeration compressor fluid that offers reliable, long-term performance with the potential for significant operational cost savings.


Type / Applications

  • Compressor
  • Food Industry
  • Refrigeration Compressors

Lower oil volatility reduces fluid consumption and maintenance costs

  • Significantly less volatile than solvent refined paraffinics or naphthenics at high temperatures
  • With proper change-out procedures, may result in reduced oil carry-over and lower fluid consumption.
  • Lower oil carryover also reduces sludging and deposit formation in evaporators, lowering maintenance costs

Lower solubility in ammonia improves system efficiency and performance

  • REFLO A is less soluble in ammonia refrigerant than solvent refined paraffinics and naphthenics
  • Less ammonia is absorbed into the compressor fluid, which can reduce foaming in separator tanks and increase system efficiency
  • Lower concentrations of ammonia in the fluid allows it to maintain viscosity, so it lubricates better, reducing wear
  • Less compressor fluid is absorbed into the ammonia, reducing the potential for fluid to block piping, valves and filters
  • 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, helping to reduce 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 performance standards
  • Extends fluid life, even in the presence of impurities in the ammonia refrigerant, saving on downtime and change-out costs

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 -39°C (-38°F)*.

Although REFLO A is compatible with most paraffinic mineral oils, 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) seals, 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 and hence should not be considered compatible for top-up with these fluids. Although tightening flanges can sometimes correct minor leaks, we advise that new seals should be retrofitted during the oil conversion. Follow the OEM’s seal recommendation for hydrotreated paraffinic oil.

Please be advised the REFLO products are not recommended for top-up on pre-existing refrigeration compressor fluids with different chemistries. For example, REFLO A, XL (paraffinic) and Synthetic (PAO) should not be mixed with naphthenic or aromatic type fluids. REFLO CFC is a naphthenic fluid and should not be mixed with paraffinic fluids. Doing so results in increased risk of seal damage/leaks and reduced performance.
