Dehumidifier Rentals In New York Ice arenas can be challenging to maintain consistent moisture and humidity levels that will keep a large area of ice frozen. Common issues for these facilities include fogging, condensation, and humidity. These issues peak in the late spring/early summer months or any time warm ambient conditions are present. In addition to a changing climate, old or undersized HVAC equipment that cannot keep up with the rising climate can cause problems. Add sold-out capacity crowds and find your facility in less than favourable conditions.
