Air Heat Exchangers

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.

Copper Finned Tubes

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.

Stainless Steel 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.

Carbon Steel Fin Tube

  • Operating Temperature up to 320°C (608°F)
The L type fin is commonly known as L fin. This finned tube is basically identical to the Wrap-On fin and produced with a combination of Wrap-On and Embedded.The fins are manufactured from strip which is preformed into an accurately controlled L shape similar to the L type, rolled into a taper which causes it to curl. It is then continuously helically wound under tension onto the tube. The fin hugs the tube. The base tube is knurled by a rotating tool, then the foot of the fin is knurled into the knurling of the base tube providing a tight bond with increased thermal performance. Providing the correct fin strip is used the foot of one fin butts up against the next fin and there is no gap between the fins. This gives some corrosion protection to the tube. The fins are secured at each end to prevent unwinding in a similar way as L fins.

Tube Finning Machine

Continuous SpiralL Wound Finned Tubes have crimpL 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 CrimpedL. 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.

Wire Wound Fin Tubes

These tubes are manufactured using wire in place of strip and wound helically over the tube with root soldering at foot to avoid air gaps between fin and the tube resulting in to higher heat transfer efficiency, reliability and longer service tube.
