• Reduced oil carryover
  Low volatility and greater ammonia immiscibility help prevent oil from reaching the evaporator, promoting refrigeration efficiency and reduced maintenance. The low pour point and good viscosity index ensure that any oil which does reach the evaporator will drain more rapidly than a naphthenic oil.
  
  
• Equipment and lubricant life extension
  Reduced sludging and formation of harmful deposits in the high temperature environment of the compressor as compared to naphthenic oil. As a result, equipment life and lubricant life can be extended while reducing maintenance.
  
  
• Stable viscosity
  Group II base stock properties allow the oil to maintain a stable viscosity, staying in grade longer than a naphthenic refrigeration oil.
  
  

• Capella® P 68 provides effective wear protection for reciprocating, vane, and screw compressors.

• Capella® P 68 formulated with Group II paraffinic basestocks, is designed to specifically address the requirements of ammonia refrigeration systems.

• Rotary screw, reciprocating and rotary vane compressors in ammonia refrigeration systems
  
  
• Recommended for use in systems using refrigerant R-22 and R-502 provided the evaporator temperature is above -30°C
  
  

Not recommended for systems using refrigerant R-12 or R-134a.
