Europe’s first ice arena with transcritical CO2 refrigeration

In early 2013 the roof of the ice arena collapsed in the little community of Gimo in Östhammar municipality, about 120 kilometres north of Stockholm, Sweden. When the building was restored in 2014, a new cooling system and ice rink were installed. CO2 refrigeration from Green & Cool was chosen, making the Gimo ice arena the first in Europe to cool its ice rink using pure CO2 technology. The unit from Green & Cool was delivered and installed by Industry & Laboratoriekyl.

“Working together with Green & Cool, we have resolved the oil handling issue, which now makes it possible to use only CO2 as refrigerant also in ice rinks. The concept is very beneficial for clients. We are about to launch a major marketing campaign along with Green & Cool, including a website about ice rinks and CO2 refrigeration,” says Patrik Larsson, CEO, Industri & Laboratoriekyl.

The unit in Gimo ice arena is a Green & Cool Mistral, with an effect of 250 KW. The unit naturally also has heat recovery. Most of the waste heat from the cooling process is recovered and used for site heating and hot water. Excess heat is transferred to five drilled wells, 200 metres deep, which provide geothermal energy storage.
