Repairs to Condenser Coil on a York Chiller

Repairs to Condenser Coil on a York Chiller

Job Description:  Repairs to Condenser Coil on a York Chiller

Area: Longwater Ave, Reading

Issue Identified:  Following a recent planned preventative maintenance visit our engineer found a leak on the condenser coil on circuit 1 of the York Chiller. We recommended to cut out bottom couple passes of the coil.

Works carried out:

  • Isolated the York Chiller electrically and mechanically.
  • Released the Nitrogen from the circuit.
  • Cut and sealed the bottom passes from the coil.
  • Re-pressure test with OFN (oxygen free nitrogen) to prove system was leak tight.
  • Once proved released OFN to atmosphere and evacuated system to a minimum of 2 Torr.
  • Re-charged with virgin refrigerant.
  • Test ran and re-commissioned.

Features and advantages of the York Chiller

The benefits of a York Chiller are reduced emissions, greater flexibility, more sustainable and better control. Designed for temperature sensitive operations such as data centres, manufacturing, and hospitals. ACES have a team of highly trained York specialist engineers. We offer a 24/7 service with most of our engineers based in London.
