GRH was awarded the design & installation of a new low use out of hours chiller & chilled water circuit to be added to an existing 24hr chilled water circuit serving comms rooms.
Connections to the existing system was made to the existing 150mm secondary pumps via a PHE and control valves to change over the cooling source when out of normal hours working.
The new 80mm chilled water services were 100% welded off site to remove the need for on-site hot works.
All new servicers were balanced and thermally insulated on completion.
GRH Completed all works on schedule.
