Air Fin Coolers



Our company is enagaged in manufacturing, exporting & supplying of Air Fin Coolers. Air Fin Coolers is used to exchange the Heat between Air/Gas on one side & Air/Gas/liquid on other side. We use External Fins in the Air Fin Coolers to increase the heat transfer area. The fins are selected on the basis of parameters like fouling nature of the air/gas, air/gas to be cooled, available area, etc.

The common types of fins are :
  • Integral Fin
    • The Tubes are finned on the OD of the Tube
    • This increases the Heat Transfer Area of the Tube by 3 to 3.5 Times as compared to Plain Tube, with a minor increase in the cost
    • These Tubes find applications in the AC Plants/Oil Cooler, Condensers, etc. Carbon Steel, Stainless Steel, Copper, Copper Alloys can be finned
  • L Type Fins
    • The aluminium strip foot section is first formed into an L shape and then tension wrapped on to the base tube
    • Wound fin base sections are close to each other so as ensure a continuous cover over the primary tube surface
    • Finally, the fin strip is fastened at ends to prevent loosening
  • Plate Fin
    • Plate Fin generally consist of a thin strip of either aluminium, Galvanized Iron, Copper etc which is slipped over the OD of the Tube
    • Necessary operation is done to ensure proper contact between the OD of the Tube and Tube Hole ID of the Plate Fin
    • The Pitch of the Holes in Fin is accordingly to the Tube Layout of the Tube Sheet
  • G Type Fins
    • The aluminium strip foot section is first formed into an L shape and which is tension wrapped and embedded into the primary tube wall
    • These type of tubes have better life vis a vis the L type of Fins find applications in Refineries
  • Spiral Tension Wound Tubes
    • Here Plate Fin is tension wound spirally on the od of the tube, ensuring proper contact between the OD of the Tube & Plat Fin
    • Plate Fin material can be Aluminium, Carbon Steel, Copper, while Tube material can be Carbon Steel, Stainless Steel, Copper, Copper Alloys, etc.
