In concrete or sand, the ProCurl curling rink piping system by Custom Ice will enhance conditions in any rink. More uniform ice temperatures will result in more consistent speed and curl from shot to shot. The closer pipe spacing is ideal for curling to prevent a rock from hanging outside over a wider spaced 1" pipe. With a larger pipe surface area, the ProCurl system will increase heat removal rates and improve refrigeration system response time helping to keep ice temperatures consistent and uniform across the entire sheet. A perfect curling match! More even pipe spacing, even heat transfer, even ice temperature and even better ice.
