Ammonia Refrigeration Lubricants

Better Performing Lubricants for Ammonia Systems

CPI Fluid Engineering lubricants are specifically designed to operate with optimal performance in ammonia (NH3) refrigeration systems.  CPI lubricants can provide cost benefits through extended drain intervals, fewer filter changes, and less downtime.  These lubricants also minimize the amount of NH3 that dissolves, aiding in enhanced lubrication.

Semi-synthetic and synthetic lubricants provide improved performance in ammonia-based refrigeration systems over traditional mineral oils. Benefits include: 

Cleaner operation

  • Oxidatively stable – reduced sludge and varnish build-up, longer system life
  • Corrosion protection – enhanced system reliability, reduced down-time

Low volatility

  • Decreased maintenance
  • Significantly reduced lubricant consumption

Low carryover

  • Improved evaporator efficiency

Low pour point

  • Easier oil removal

Cost savings

  • Longer oil life
  • Reduced oil changes
  • Extended drain interval
