ICS Cool Energy, part of Trane Technologies, is expanding its temporary cooling hire services for data centres in the UK and Ireland, according to a company release published by Data Centre Solutions, a move that matters to data centre operators and energy buyers because it treats temporary thermal support as planned resilience for live sites rather than only an emergency response.

ICS Cool Energy is an international supplier of temperature control solutions for manufacturing process and facilities applications, with a chiller hire fleet of more than 500MW, according to its website.

Trane Technologies is the Ireland-headquartered climate technology group of which ICS Cool Energy is part, and ICS said it draws on that ecosystem for equipment and technical expertise.

According to the release, the service covers temporary chillers with synchronised load banks and metering during commissioning, cover during plant overhauls to maintain N+1 redundancy, rapid contingency cooling, supplemental cooling for peak demand and interim capacity for phased fit-outs.

Dave Palmer, managing director of ICS Cool Energy UK and Ireland, said in the release: “In data centres, uptime is everything. While sites are designed with multiple layers of resilience, temporary cooling provides an additional operational safeguard when permanent plant is unavailable, being tested or taken offline for maintenance.”

The IEA says cooling accounts for about 7% of consumption in efficient hyperscale data centres and over 30% in less efficient enterprise ones.

The Central Statistics Office reported that data centres used 23% of Ireland’s metered electricity in 2025, up from 5% in 2015.

Uptime Institute’s 2025 survey put average data centre PUE at 1.54, little changed for six years, according to its annual report.

Under the CRU’s connection policy, new Irish data centres must provide dispatchable onsite or nearby generation or storage matching their maximum import capacity, according to the regulator.

The release is company-supplied and names no customers, so the service’s scale and uptake are unconfirmed.

For the sector, a cooling hire provider targeting commissioning, maintenance and peak load shows data centre resilience spending extending from standby power into thermal management, where energy use is significant.
