Stable Humidity Control for Indoor Ice Rink
We supplied a desiccant dehumidification system for an indoor ice rink that was experiencing persistent moisture problems affecting ice quality, visibility and structural integrity. The project demonstrates how controlled humidity and dew point management can prevent condensation and fog in cold recreational environments.
Moisture Problems Affecting Ice Quality and Visibility
The facility had ongoing issues caused by warm, moisture-laden air entering through small air leaks and regular door traffic. As this moisture accumulated, the indoor dew point increased. When the humid air contacted cold internal surfaces such as steel roof beams, rink barriers and other chilled structures, the dew point was reached and water began to condense. The resulting droplets created localised dripping, which damaged the ice by forming pits or “ice mushrooms” that affected skating quality.
During warm periods, the high moisture load also led to indoor fog. This reduced visibility for skaters and spectators and created an uncomfortable environment throughout the rink. The ice surface, surrounding building fabric and electrical equipment were all at risk due to the combination of condensation, high relative humidity and fluctuating conditions.
DST’s Desiccant-Based Solution
We supplied a desiccant dehumidification system configured to maintain either constant relative humidity or a controlled dew point specifically suited to an ice rink environment. By keeping the indoor air dew point lower than the temperature of cold surfaces, the system prevented condensation from forming anywhere within the rink. This approach also stopped fog formation, as the air remained dry and stable even when external conditions introduced significant moisture. The system dried both recirculated air and a controlled volume of fresh air where required. This prevented moisture spikes caused by air infiltration and regular door openings. The continuous drying process kept environmental conditions stable despite varying occupancy levels, external humidity changes and the operational patterns of the rink.
Installation and System Integration
The DST dehumidifier was integrated into the rink’s existing air movement arrangements with minimal disruption. Airflow paths were designed to ensure dehumidified air reached all areas most exposed to infiltration and moisture accumulation. The system was set to operate continuously, maintaining steady conditions at all times without requiring major changes to the building structure or mechanical services.
Positive Client Feedback
Rink management reported a marked improvement in environmental stability soon after commissioning. The ice surface remained in consistently good condition, free from water drips or localised damage. Visibility improved due to the removal of fog events. Staff also noted the reduction in corrosion risk, mould formation and moisture affecting electrical circuits. The system’s reliability and low ongoing maintenance requirements were highlighted as significant advantages for a facility that must operate continuously.
Results Achieved
The installation delivered several clear improvements. Condensation was eliminated, keeping the internal structure dry and protecting mechanical components. Ice quality remained smooth and stable with no pitting or formation of “ice mushrooms”. Fog events ceased entirely, creating a safer and more comfortable environment for users. Lower humidity also reduced long-term risks to the building fabric and electrical systems.
Summary
The DST desiccant dehumidification system provided an effective and reliable humidity control solution for the ice rink. By regulating dew point and ensuring continuous moisture removal, the system protected the ice surface, prevented fog, reduced structural and electrical risks and maintained safe conditions throughout the facility.
Facilities experiencing condensation, fog or moisture-related damage can benefit from the same level of control. If your site faces similar humidity challenges, DST Humidity Control can help assess requirements and supply a suitable solution.
