Refrigerant leak testing/detection of a sealed refrigeration circuit takes place right after Refrigerant Filling and/or after Performance Testing.

  • The leak detector is a manually-held probe or automatic multiplexer with gas traps
  • It is the final leak test and is usually performed during/after run test.
  • The leak detector technology is based on an Infrared Sensor which is very sensitive (in the range of 0.03 ounce or 1 grams per year of refrigerant) and offers fewer false alarms compared to Halogen-based detectors.
