Indoor ice rinks possess a high level of air humidity due to their unique environmental conditions. Excessive humidity within the rink can cause fogging on the ice surface, impairing visibility. Excess moisture in the air may also condense on ceilings, causing water droplets to fall onto the ice surface. This results in uneven ice conditions, posing hazards to athletes and compromising performance for speed skaters and other competitors by softening the ice. The HBC rotor dehumidifier effectively regulates humidity levels within ice rinks, mitigating issues such as surface fogging. Its low-energy consumption characteristics further reduce maintenance costs for rink operations.
