Humidity in the ice rink has a big impact on the quality of the ice. A high level of humidity provides a rugged surface with a lot of snow production when in contact with the sharp blades of a skate.
You should strive for an optimal humidity of 50-55%, this is especially important when you have a large crowd that often contributes to an increased humidity level.
It is also crucial that you keep an eye on the fresh air intakes to the arena, these should not be near any streams, lakes or other humidity sources, or you might compromise the quality of the ice and the arena ice maintenance.
By using unheated water to resurface your ice, the REALice® system can help tremendously to lower down the humidity levels in your arena.
