Liebert Chiller Pressure Leak Test
Job Description: Liebert Chiller Pressure Leak Test
Area: Data Centre, Hounslow
Issue Identified: Following a planned preventative maintenance visit on a Liebert Chiller, our engineer discovered a leak on the circuit 1 and therefore the chiller required a pressure leak test
Works carried out:
- Isolated the 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 leak.
- Discovered the evaporator had split which caused water to mix with refrigerant.
- Findings reported.
- Awaiting further works order.
