About

North Metropolitan Health Service awarded a contract to Grosvenor Engineering Group (Grosvenor Engineering Group Pty Ltd) for the protective recoating and associated removal, transport, surface preparation and reinstatement of Chiller 4 condenser water boxes, end plates and tube sheets after coating failure was identified during the annual condenser cleaning/servicing.

The scope of works included draining the chiller; gaining site access and moving equipment within the plantroom; unbolting and removing condenser end plates and two water boxes; loading water boxes onto a transport truck for off‑site coating; building encapsulation at both ends of the condenser tube sheets to capture dust and debris from blasting; covering chiller components to minimise dust encroachment; sand blasting and re‑coating of the water boxes, end plates and tube sheets; organising delivery back to site and reinstalling two water boxes and end plates; filling the condensers and pressure testing to confirm no leakage; and putting the chiller back into service.
