EKA’s ice rinks and CO2 projects in Sweden

We have made a visual documentation of the ice rinks and CO2 projects that we have worked with in recent years. See where they are situated and read more about them here!

Project Stoppsladd

On behalf of the Swedish Energy Agency, EKA together with the Swedish Ice Hockey Association has conducted an energy and technology inventory of Swedish ice rinks. The main goal and purpose of the work was to demonstrate the energy saving measures that can be implemented to reduce the energy used in ice rinks. One of the conclusions of the project was that by simple means (low investment) the energy consumption can be reduced by about 20 percent. >Läs mer

Europes first full CO2 Ice Arena

We have designed Europe's first full CO2 refrigeration system to the rink in Gimo. Carbon Dioxide refrigeration increases in ice rinks where otherwise ammonia along with various secondary refrigerants have been used for a long time. Recently, a new generation of CO2 systems has come into play. There are several advantages in terms of both investment costs and energy usage. >Read more


Together with the Swedish Ski Association, Dalarna County Administrative Board and the Swedish Energy Agency we tested the energy usage of snow cannons. The purpose was to measure the energy use in artificial snowmaking and presenting proposals for energy savings. The tests were conducted with mobile snow cannons at the ski stadium Lugnet in Falun. >Read more

Energy efficient Milk Cooling

In cooperation with Wedholms AB and Kylbranschens Samarbetsstiftelse (KYS) EKA leads the project Energy efficient milk cooling. The project aims to demonstrate the energy savings at the milk cooling with an improved control strategy of the existing technical components of the cooling refrigeration system. >Read more

The Ice Hotel in Jukkasjärvi

EKA has performed field measurements of existing refrigeration systems in the Ice Hotel's warehouse. The results have contributed to a new design and the choice of new environment-friendly refrigeration technology based on carbon dioxide as refrigerant.
