An emergency chiller solution from ICS Cool Energy safeguarded cooling for a large hospital in central England during major infrastructure upgrades.
As part of the programme, the hospital wanted to further strengthen the resilience of its cooling system. Ordinarily, one chiller would operate while the second remained on standby. During the upgrade works, the facility management team needed to run both chillers simultaneously even under moderate conditions. This temporarily removed built-in redundancy and increased strain on the system.
With summer approaching and temperatures rising, the hospital required a reliable, efficient cooling system to ensure continuity across critical clinical spaces, operating theatres, wards, and communal areas. To support uninterrupted services and mitigate operational risk during the upgrade and high-demand season, administrators engaged ICS Cool Energy to provide temporary hire chillers as part of an integrated solution.
The solution centred on the installation of four 500kW chillers. To overcome limitations in the site’s existing power supply, ICS Cool Energy also provided two high-capacity 800kVA generators, ensuring uninterrupted operation throughout the duration of the works.
Engineers navigated logistical complexities, including the safe routing of hundreds of metres of flexible hose from ground level up to the rooftop plant room and the placement of equipment in a confined access route, all while keeping essential hospital access clear for emergency vehicles and staff.
The team also completed calculations to account for pressure drops throughout the pipework. While the hospital’s main circulating pumps remained incorporated within the setup, additional measures were taken to sustain optimal flow and pressure across the temporary installation. Four 4-inch pumps were fitted on the suction line, complemented by an inverter-driven 4-inch pump on the delivery side. This configuration ensured that water circulated efficiently, maintaining stable cooling performance in all areas of the building at all times.
