Cooling and heat recovery for data centres.

A data centre rejects heat while its IT equipment operates. We assess heat-pump cooling and recovery around the measured load, useful heat demand and resilience requirements. Ground arrays are considered only where their long-term heat balance and capacity suit the duty.

What we do

Two duties, one coordinated system.

Cooling and heat reuse need to be assessed together. The design starts with the operating load and a reliable rejection route, then tests whether a useful heat demand is available.

Efficient cooling

Ground or water sources may contribute to cooling for suitable loads. Continuous heat rejection can warm a borefield, so capacity and seasonal heat balance must be modelled; additional heat rejection may be needed.

Waste-heat recovery

Heat pumps lift low-grade server heat to a usable 35–80°C for space heating, hot water or a nearby demand — energy the site would otherwise pay to throw away.

Resilience first

Recovery is only viable when the cooling duty is protected. We design an independent rejection route, so heat reuse never becomes a single point of failure.

How it works

From server load to useful heat.

Qualify the load

IT load, coolant or air temperatures, operating profile and the resilience the operation demands.

Protect the cooling

An independent heat-rejection route is designed first — recovery is an addition to the cooling system, never a dependency of it.

Lift the temperature

A heat pump raises captured low-grade heat to 35–80°C — usable for heating and hot water.

Serve a real demand

Recovered heat is matched to a demand nearby — offices, hot water or process pre-heat — with timing, distance and contracts assessed honestly.
