Climaveneta has supplied two heat pumps for Fortum to help the Finnish energy company to utilize waste heat from a data center and supply the heat into a district heating network.

According to the Mitsubishi Electric Hydronics & IT Cooling Systems group company, the converted heat will be supplied to Fortum’s customers in Espoo district in Finland.

The data center is owned by Ericsson which requires surplus cooling production to accommodate its rapidly increasing IT load. Climaveneta says that the Swedish telecommunications equipment supplier had old cooling equipment that wasn’t capable of handling new incoming IT loads.

Ericsson was searching for a solution for the problem that was economic and ecological at the same time.

Climaveneta HVAC system designer Petteri Hajanti said: “It was clear from the very beginning that we wanted to recover all waste heat available and not waste any of it to the environment.

“With minor modifications we were able to convert the data center to a heat production plant and simultaneously with the same equipment, able to provide the cooling for the data center.”

Fortum on the other hand was looking for a sustainable solution to deliver continuous heating capacity to its local district heating network. Further, it needed the solution to be implemented without much investment cost and payback time.

Fortum’s Mottonen Ilkka said: “We want to produce heating in a sustainable and of course innovative way and this project shows that we are able to do that.”

The two heat pumps are of Climaveneta’s FOCS2-W HFO/H/CA/S 5422 range and were supplied through Nordic critical facility solutions provider Coromatic.
