Desiccant dehumidifiers in Ice Rinks

Moisture from warmer outside air will inevitably find its way into the building through natural leakage and door use. This often results in an increased relative humidity of the cool ice rink air.

When the humid air comes into contact with colder surfaces (eg: steel roof supports), the air can easily reach its dewpoint and condensation will occur. Dripping water will cause damage to the ice by pitting the surface or by forming "ice mushrooms", thereby lowering its overall quality. Indoor fog can be a common problem, especially in Summer when the dewpoint of outside air is at its highest.

A desiccant dehumidification system is designed to maintain a constant relative humidity or dewpoint within the ice rink.

The dry recirculated air is prevented from reaching its dewpoint - irrespective of surface temperatures.

Condensation and fog are eliminated !

A lower humidity also helps to prevent formation of mould and mildew growth, reduces steel corrosion and improves general safety of electrical equipment.
