Better conditions at Kvik Hockey Arena in Herning, Denmark

Slicing ice rink operating costs multiplies bottom-line benefits

Conditions and operating costs are crucial for ice rinks

 

The Kvik Hockey Arena in Herning – home of many-time Danish champions and medal winners the Blue Foxes – is a powerhouse in professional ice hockey in Denmark, and has to provide top-quality facilities at all times.

A key part of this involves controlling the humidity of the air inside the arena, which houses both the main rink and a training rink.

 

Energy issues, cost burdens

The main challenges facing modern ice rinks usually centre around misting and condensation above the ice and on all kinds of structures and surfaces. Condensation forming on the ceiling surfaces, and then dripping onto the ice, players and spectators, is a particular problem. Dripping can also result in an uneven ice surface that affects play, while condensation can also form on the rink-side security glass, affecting everyone’s view of the game.

As a professionally run business unit, the arena also has to keep a keen eye on all forms of expenditure. The owners were concerned that the dehumidifier dealing with airborne humidity in the main rink was running non-stop round the clock – regardless of requirements.

And also that the dehumidifier system was running solely on electrical power – which in Denmark is the most expensive form of energy.

 

Rethinking, replacing and refurbishing

A radical rethink of the arena’s humidity management systems was called for. Cotes calculations showed there is actually no need to use expensive electricity for air regeneration in the dehumidifier installations.

Instead, Cotes experts replaced the old, expensive-to-run dehumidifier in the main rink with a Cotes CRT9000EV unit, and rebuilt the existing Cotes CRT9000E unit in the training rink. Both units are now controlled by actual measurements of dew point, not by relative humidity. Even more importantly, they now use surplus energy from the rink’s main heating and cooling plant for the regeneration air used in the dehumidifiers. This energy previously mostly just went to waste.

The new Cotes CRT9000EV unit uses sensors to determine the dew point down at ice level, and is fitted with a special DH50 controller to make it exceptionally easy to operate. Proper monitoring and adjustment of the dew point translates directly into big savings on one of the biggest expenditure items on the operating budget for this high-profile venue.

Such major savings in operating costs then make it possible to open up for improvements in the facilities, service and comfort the arena can provide for users – as well as their families and other ice hockey supporters.

 

“The dew point and levels of humidity are exactly as we want, and it only takes me a few seconds to make any small adjustments needed, based on my experience of hall conditions and event expectations.”
