Monometallic finned tube with fins drawn from the parent metal of the tube. All monometallic Tubes are using a cold rolling or ribbing process.

Materials: Aluminium, copper, brass, cupronickel, carbon steel, stainless steel, titanium, nickel alloy, etc.

FPI: 12, 16, 19, 28, etc.

OD: 1/2"-1"

The extruded finned tubes are formed in a cold rotary extrusion process, where continuous helical fins are radially extruded from a thick aluminium muff over a liner tube. The process of extrusion hardens the fins and prevents dissimilar metal contacts at the fin root. Compared to other products, fins do not break, unwind or become loose which affects greatly thermal efficiency.

Applications:

Aftercoolers, air coolers, air heaters, charge air chillers, condensers, convection heaters, electric heaters, evaporators, fluid coolers, gas coolers, heat pipes, hydrogen coolers, industrial tumble dryers, intercoolers, immersion heaters, oil coolers, radiators, refrigeration, solvent recovery and steam to air heat exchangers
