An ice sheet is designed just like a refrigerator, when the dasherboards are open, it allows the heat to enter the ice requiring the ice plant to work harder to take that extra heat load off. On top it will make the ice softer.

Open doors to the outside have the same effect, but in addition makes it much harder to control the humidity levels inside the arena.

Fast-opening loading doors could cut down the amount of cool air that leaves the arena.


  • Hard ice
  • Less load on the plant


  • Electricity
  • Natural Gas (de-humidifer has to work less)
  • CO2
