  • Maximum efficiency
  • Stable operation
  • Proper TXV feeding
  • Reduced service calls
Low Subcooling Issues:
  • Undercharged system
  • Refrigerant leaks
  • TXV hunting
  • Capacity loss
  • Efficiency reduction
High Subcooling Issues:
  • Overcharged system
  • Restricted metering device
  • High head pressure
  • Reduced capacity
  • Equipment damage risk
