PLUTO PA is high quality refrigerator compressor oil formulated from refined paraffin mineral oil with most advanced additives, very low pour point, low mixable suitable for refrigerator compressor  using refrigerant: Ammoniac (NH3).


  • Pluto PA is optimized for refrigeration compressor systems that require oil separation.
  • Low volatility, reducing the oil vapor loss, ensuring long-term and stable operation.
  • High thermal stability and oxidation stability, maintaining good oil properties even under high exhaust air temperature conditions.
  • Prevent the formation of sludge and sludge, which provides easy lubrication throughout the system, extends the life of the oil and equipment.

Specification and Approvals
