NDL Industries Inc. is the premier producer of ACR Copper Fittings and Ball Valves
NDL started in 1987 as a mechanical engineering firm, consulting to the refrigeration industry in Canada, USA, Australia and New Zealand. In 1998, the engineers at NDL recognized a need for more complete ACR copper fitting as new refrigerants emerged. The focus at NDL shifted from consulting to production, with the result being an elite ACR Copper fitting like no other in the industry.
