We have developed, Spiral Fins without Tube i.e., Fin Coil Specially for Shaped or any other old fabricated shaped tube. These are widely used for industrial electrical air fin heaters and air compressor cooling tubes. These Coil Replace the old fashioned, Washer type, Separate Fins. Instead of putting separate one by one single washer fin. They can put about 200 fins at time, using our continuous coil of fiats. By this more fin heater can be made lesser time. Thus saving substantially on Labour cost. Because of uniform spacing on fins, Tubestted with these coils have a very appealing get up. More over total heat transfer efficiency increase substantially because of continuous crimped fin design. Fin coil have been well received by heater manufacturers and users. These fin coils are made according to the OD of the Tube with tractional Differences. Coils suitable for tube ODS. In mm 8, 8.3, 8.5, 8.6, 9, 9.2, 9.5, 10, 11, 11.5, 12, 12.5, 12.7, 13, 14, 15, 16, 17, 19, 22, 25, 27, 28 and above any size upto 50 mm. Fin out side diameter min 20 to max 88 mm. (Depending on the tube OD). Fin spacing: From 2 to 10 Fines per inch. Material mild steel, Stainless steel and copper. Selected raw materials, Strict adherence to specification, Quality assurance. Best workmanship.
