Trane Chiller Pressure Leak Test

Job Description:  Trane Chiller Pressure Leak Test

Area: Jermyn Street, London

Issue Identified:  Following a planned preventative maintenance visit our engineer advised that the above chiller was tripping on low pressure and required a pressure leak test.

Works carried out:

  • Isolated the Trane Chiller unit electrically and mechanically.
  • Recovered refrigerant into certified cylinder for storage on site.
  • Weighed and confirmed the charge.
  • Pressure tested with OFN (oxygen free nitrogen) to locate any possible leak.
  • Removed redundant H.P. switch from circuit 2 and replaced with a Schrader fitting.
  • Replaced single core drier.
  • Re pressure tested.
  • Once proved released OFN (oxygen free nitrogen) to atmosphere and evacuated system to a minimum of 2 Torr.
  • Re-charged with recovered refrigerant and trim charged with virgin refrigerant.
