NDL Industries

We started in 1987 as a mechanical engineering firm, consulting the refrigeration industry in Canada, the U.S., Australia, and New Zealand. Then in 1998, our engineers recognized a need for a more complete ACR fitting as new refrigerants emerged. Our focus began to shift from consulting to production, with the result being an elite ACR copper fitting like no other in the industry. Since then, we have grown our selection to 23 product categories in the HVAC-R, CO2 Refrigeration, and Plumbing space.

Our CRN-approved CO2 ball valves and check valves hold five times the maximum working pressure, netting a tremendous safety margin for any valve used in a CO2 system. These valves are paired with our selection of UL-listed CO2 copper fittings (C19400 high-pressure copper) specifically designed for use in CO2 refrigeration and HVAC systems.
