Continuous Spiral/‘L’ Wound Finned Tubes have crimp/‘L’ fins, which increases the overall heat transfer surface area. Quicker decipation and higher heat-transfer coefficient is obtained in equipments fitted with Fin Tubes. Continuous Spirally Crimped/‘L’. Fin Tubes are made under high mechanical tension bonding process, in which fin material is helically wound over the tube to get maximum contact of tube & fin and only end of fins are brazed/welded to core tube. Therefore it achieves the highest efficiency and withstands high internal pressure.
These are used for heat transfer i.e. cooling / heating of water, steam, air gases, oils & many other vapours, fluids etc. These tubes are used in Fin Heat Exchangers, Steam Radiators, Autoclaves, Condensers, Dryers, Ovens, Furnaces, Air Heaters, Oil Coolers, After Coolers, and Air Compressors & in many other Heat Transfer Equipments. Fin Tubes are widely used by chemical, Petrochemical, Fertilizer, Food, Pharmaceutical, Paper, Textile & several other industries. These space saving, high efficiency Continuous Crimped Fin Tubes are made in Mild Steel, Stainless Steel, Copper, and Brass etc. or in different combinations of materials. However ‘L’ type fins on made in Mild Steal, & Copper only, and tube material may be Mild Steel, Copper, Stainless Steel, Brass etc
Continuous Spiral Fins (Without tube), Fin Coils are used for U shaped or any other odd shaped fabrication tube.These are widely used for industrial Electric Air Fin Heaters and Air Compressor’s 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 Continuous Coil of Fins. This can make more Fin Heaters in lesser time, thus saving on labour cost substantially. Because of uniform spacing of fins with these Coils have a very appealing get up. Moreover total Heat Transfer Efficiency increases substantially because of Continuous Crimped Fin design.This machine works on the principle of Roto Advancing mechanism of tube, and fins are crimped and wound around the periphery of the tube under high tension.
