The CerroGroove(tm) copper tube is said to provide superior heat transfer capacity, making it a perfect fit for design engineers and manufacturers of high-performance air-conditioners, refrigerators, evaporators, and condensers. The grooved copper tube is said to allow manufacturers to produce smaller cooling units to meet size restrictions or requirements, yet maintain the same cooling capacity as larger units. The copper tube meets ASTM specifications B743 and B903 and is currently available in sizes ranging from 5/16 to 3/8 in. Bending and expansion characteristics of the tube are said to be virtually the same as a smooth-wall tube.
