A Customer Success Story

When this hospital needed a fast solution for their pathology building cooling they turned to ACR for a fast effective solution.

The hospital had been having problems with their roof mounted fixed chiller. They needed a temporary replacement quickly to maintain operation of this important facility. The chilled water feeds a chilled beam system which air conditions the building.

The Solution

ACR recommended an direct like for like replacement water chiller hire at 220kw. It was proposed that the chiller be mounted at ground level for fast, economical installation- a crane lift to the roof would be expensive and time consuming. It was also unclear if a suitable load tested position could be authorised quickly.

Mounting the chiller at ground level presented its own problems in terms of the pipe-work installation but it was decided that this was the preferred option.

water chiller hire- installing hose

A 3″ rubber pipe-work system installed to connect the temporary chiller to the clients access points in the roof plant-room. Using a cherry picker the hose was run down the side of the building and attached using feature grills for support- padding was used to prevent damage around the fixings.

The temporary pipe-work was connected to isolated 100mm flanges and adapted down to accommodate the 3″ hosing with Camloc connectors.

The temporary chilled water pipe-work was manually filled to prevent air entering the clients system. Gradual opening of the clients valves allowed the pressure-set to pressurise the system before fully opening to complete the circuit.


The completed system was tested and commissioned at full load- no problems were encountered and the system was left fully operational within 8 hours of arrival on-site.

A good days work.
