Product Data Sheet

NOCOCHILL 331

 

NOCOCHILL 331 is a premium quality oil expressly designed for use as a refrigeration compressor lubricant for units utilizing ammonia refrigerant.

APPLICATIONS

NOCOCHILL 331 can be used in virtually any installation regardless of compressor evaporator temperatures.  It is ideally suited for low temperature systems where evaporator temperatures are below -18ºC, including residential and commercial refrigeration and air-conditioning systems.

IMPORTANT CHARACTERISTICS

NOCOCHILL 331 is a premium quality oil in every sense. It is blended with specially selected paraffinic base oils that have been refined to produce wax free lubricants. It will mix well, but not react with all commonly used refrigerant gases.  It does not separate wax with resulting system plugging at normal low operating temperatures.  Similarly, it is stable at the elevated temperatures encountered in the compressor itself.


PERFORMANCE FEATURES

  • Outstanding Antiwear Performance
  • Superior Thermal and Oxidative Stability
  • High Viscosity Index
  • Low Volatility
  • Low Miscibility with Ammonia

BENEFITS

  • Chemical and thermal stability to extend component service life, reducing service calls and maintenance costs.
  • Minimizes oil breakdown.
  • Cleaner operation of the compressor with fewer deposits and failures due to valve sticking. 
  • Maximizes oil film to minimize compressor wear.
  • Excellent low temperature performance with no-wax deposits to plug the system. 
  • Minimizes oil carryover, providing maximum cooling efficiency.
  • Approval by most major equipment manufacturers.
