Cooling groups are systems installed in natural ice rink areas. Natural ice rink systems are made using natural ice masses. Cooling pipes are laid on the floor of the field during ice rink production in order to protect the ice temperature. The cooling pipes laid in the underground works of the ice rink field ensure that the real ice keeps its temperature. Cooling groups are used in ice rink areas to ensure that ice rink systems are not affected by weather conditions and continue to operate.
