A liquid-cooled base station system tested in an apartment building in Helsinki

Uutta Helsinkiä

Nokia, Elisa and Efore have commercially deployed a liquid-cooled base station system in an apartment building in Helsinki, a world-first achievement that promises lower costs for operators and owners of base station sites, as well as reduced CO2 emissions by up to 80 percent In the deployment, heat emitted from the base station has been redirected to heat the building, lowering energy costs.

The Nokia Bell Labs-developed liquid-cooled base station was made at Nokia’s Oulu facility in Finland and the liquid-cooled power system was developed by power supplier Efore, with Elisa deploying the base station in Helsinki. The VTT Technical Research Centre of Finland Ltd. evaluated the environmental impact of the liquid-cooled base station and energy usage compared to those generated by air cooling in the field.

Helsinki Business Hub played a key role by identifying the opportunity and right project partners and connecting them with each other. Helsinki Business Hub is a regional development agency whose role is to enable innovation driven companies to grow and develop in Greater Helsinki.
