Ice Rings

Moisture from warmer outdoor 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 air above ice ring air.

When humid air comes into the contact with colder surfaces (eg: steel roof supports), the air can easily reach its dewpoint and condensation will occur fast. Dropping 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 outdoor air is at its highest level.

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