The chiller at the five-storey Whittles House office block in Pentonville Road has been replaced by Delrac ACS.
The company maintained the old Carrier chilled installed on site under a sub-contract from Cofatec Heatsave.
As part of the chiller replacement programme, the company provided a new steelwork support base for the replacement chiller, removed portions of the chiller enclosure to ensure that the right operating conditions were maintained. The existing roof level chilled water pipework was modified, connecting this to the new chiller.
Existing power supplies to suit the new chiller were also adapted with control wiring disconnected and reinstated as part of the site BMS.
