Rolled Lo-Fin

Integral fin tube produced by rolling and extruding from a thick wall tube of aluminum or copper which is easily cold formed. Where internal corrosion resistance is required the tube is rolled down on an inner sleeve tube which provides excellent thermal conductivity between tubes. The sleeve can be arranged to protrude at each end to facilitate fixing the headers. Maximum operating temperature 250°C.
