Ultra Low Temperature Ammonia Compressor Oil

SYN 717 is a synthetic ammonia compressor oil that has been specifically formulated for use in ultra-low temperature ammonia refrigeration systems

This formulation is ideal for systems operating down to -54OC or in systems experiencing oil return issues with other oils.


  • Reciprocating compressors
  • Rotary screw compressors
  • Evaporator temperatures as low as -54°C


  • Superior low temperature fluidity and oil return properties
  • Very low oil carryover rates
  • Low solubility with ammonia
  • Specifically designed for use in ammonia refrigeration compressors
  • Excellent wear protection
  • Long oil life, 4x longer than napthenic formulations./li>
