Durable refrigeration tubes

Great Lakes Copper ACR refrigeration tubes in straight lengths or in rolls are a durable and dependable solution for installation of both commercial and residential air conditioning units. They can also be used for different cold-storage applications in food processing, chemical industry, and refrigeration solutions for grocery stores.Their solutions meet rigorous industry standards. This makes them compatible with elevated pressure ratings of new refrigerants and they will not introduce foreign contaminants into the AC system.

Additionally, all refrigeration tubes undergo a modern and environmentally-friendly degreasing process that ensures all refrigeration lines achieve a cleanliness limit of 0.0035 g/sq according to the ASTM B 280 standards for interior surfaces. Then, upon degreasing, straight-length refrigeration tubes undergo a series of additional procedures, including deburring, nitrogen purging, and plugging in order to ensure they retain the necessary cleanliness according to the achieved specifications. This dedication to manufacturing excellence makes Great Copper Lakes refrigeration lines the preferred solution of professional contractors in the industry.
