Heft Engineers Pvt. Ltd. Mumbai, Maharashtra

Continuous Spiral‘L’ Wound Finned Tubes have crimp‘L’ fins, which increases the overall heat transfer surface area. Quicker dissipation 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 brazedwelded to core tube. Therefore it achieves the highest efficiency and withstands high internal pressure.

These heat exchangers offer following advantages over other conventionl & crimped type finned tube Heat Exchangers. Reduction in number of tubes for given B.T.U. transfer per rate area, resulting in fuel saving. The company has its own fining facilities, where finned tubes with various configuration and in variety of materials are manufactured.

Heft Engineers are specialized in to design and manufacturing of AIR COOLED HEAT EXCHANGER, using in-house manufactured finned tubes. These heat exchangers offer following advantages over other conventionl & crimped type finned tube Heat Exchangers. More surface area per square feet of heat exchanger Lower air resistance, resulting in less power to deliver the requires C.F.M. Reduction in number of tubes for given B.T.U. transfer per rate area, resulting in fuel saving Light weight easier handling More fins per inch can be incorporated on entire tube length. The combination of low friction air loses high air velocity and maximum heat transfer per square feet of face area results in extremely high heating or cooling capacity of heat exchanger in a given space.

Wire wound fin tube consists of a base tube with oval or near rectangular loops formed of wire which are wound helically over the tube with root soldering of foot of every loop to the tube. - The loop of wire creates greater turbulence thereby increasing the heat transfer coefficient. Root soldering along the entire length eliminates almost all air gaps between the fin and the tube. - For most applications, wire wound fin tubes make it possible to design a much compact heat exchanger coupled with lower pressure drop compared to conventional fin tube.

Low finned tubes are a reliable solution for controlling the temperature of gases and liquids, or for evaporating and condensing refrigerants. Thanks to their larger heat transfer surface area, they offer considerable potential to save in terms of materials and fill volumes. The wide range of dimensions offered by Wieland Thermal Solutions makes these products perfect for a broad scope of applications in the refrigeration and air conditioning industry, for oilgas coolers in machinery and plant engineering, and for intermediate vapor superheaters in process engineering.
