If we look at the HockeyAllsvenskan table objectively, one thing stands out: the top three teams all play in EKA-designed arenas. The number 1 and number 3 teams play on CO₂ ice rinks designed with EKA as the consulting engineer. The number 2 team plays in an arena where the arena climate system, ice slab, and boards were designed using EKA expertise. The number 8 team also has an arena climate system designed by us... but apparently that doesn't help all the way 😉 We don't

On 26 September 2025, the hockey season got underway at Nobelhallen in Karlskoga. BIK Karlskoga hosted Mora IK in the season opener – and the ice delivered on every level.

EKA has been involved as technical support throughout the project, from planning to commissioning, to ensure performance, capacity

At the end of August, Jörgen Rogstam from EKA held a four-day technical training course at Ferla, on behalf of CO2 Academy. The focus was entirely on the natural refrigerant CO₂ (R744) – from the basics to more advanced technology and system understanding. The training began with an introduction for the entire staff and then continued with more in-depth sessions for technicians and engineers. The modules covered areas such as system design, safety, and operational optimisatio

The renovation of Nobelhallen in Karlskoga is now underway. The project, led by NCC in collaboration with Karlskoga Municipality, includes upgrades to the A arena, an extension of the B arena, and the adjacent swimming facility. The total investment is approximately SEK 60 million, and the project is expected to be completed in autumn 2025. At the heart of the technical work is the refrigeration system, with Kylmekano as the contractor and EKA continuing to provide technical

Forskare med bakgrund från KTH och industriella tillämpningar presenterar ny modell för att optimera värmeåtervinning i CO₂-kylsystem för stormarknader. Resultaten visar upp till 17 % högre effektivitet vid tvåstegs återvinning, och lyfter vikten av rätt arbetstryck – med praktisk vägledning för energieffektiv design.
