We have developed continuous spiral fins (without tube) i.e. Fin Coils, Specially for U, & Inverted multiple U() shaped any other odd fabricated shaped tube.
These are widely used for industrial Electric Air Fin Heaters and Air Compressors Cooling Tubes. These Coils 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 a time. Using our continuous coil of fins. By this more Fin Heaters can be made in lesser time. Thus saving substantially on labour cost. Because of uniform spacing of fins, tubes fitted with these coils have a very appealing get up. More over total Heat Transfer Efficiency increases substantially because of continuous crimped fin design. Our Fin coil have been well received by Heater Manufacturers & users.
Those Fin Coils are
Made according to the OD of the tube with fractional differences.
Coils suitable for Tube ODs, in mm 8, 8.3, 8.5, 8.6, 9, 9.2, 9.5, 10, 11, 11.2, 11.5, 12, 12.5, 12.7, 13, 14, 15, 16, 17, 19, 22, 25, 27, 28 & above any size upto 50 mm.
Fin out side diameter min 20 to max 88 mm (depending on tube OD).Fin Spacing: from 2 to 10 fins per inch.
