Man made ice rinks are used to provide a uniform repairable surface for skaters of all types. Whether the surface is used for high stakes sporting events or recreation; it is critical to be able to maintain the integrity of the ice sheet. The most important component of building an ice rink is the indirect cooling system underneath the ice sheet. A refrigerated brine solution is pumped through a maze of pipes located underneath the ice sheet to keep it frozen. Deionized water is put down in thin layers freezing on the chilled surface until it is about one inch thick. The use of deionized water allows clear ice to form. By doing this the painted markings, if any are needed, are visible regardless of the amount of surface chipping from skating.
