Heat Exchangers

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.

We are a credible Manufacturer, Exporter & Supplier of Intercooler Heat Exchanger. The air that gets heated up at various stages of compression is cooled by the Intercooler Heat Exchanger. The Intercooler Heat Exchanger we offer is suitable for compressors manufactured by M/S Ingersoll Rand, Kirlokskar, Khosla, Chicago Puematic, Atlas Copco, etc. We manufacture the Intercooler Heat Exchanger using Carbon Steel and Copper/Stainless Steel/Admiralty/Cupro-Nickel (90:10)/Cupro-Nickel(70:30) tubes depending upon the type of cooling water available, as per codes laid by clients such as TEMA RCB and ASME Codes.

We are a well-known Manufacturer, Exporter & Supplier of U Tube Bundle Heat Exchanger. Inter  Fitment being a crucial point, we manufacture U Tube Bundle Heat Exchanger either as per the specifications laid by the customers or we send our engineers to take the actual dimension of the existing Tube Bundle and the Shell. For the making of U Tube Bundle Heat Exchanger, we have a set of fixtures for 3/2" & 1" OD Tubes. The minimum Bending Radius carried out by us so far is 1.5D. U Tubes manufactured by us meet the TEMA Acceptance Norms of 16 % thinning & 10 % Ovality. The U Tube Bundle Heat Exchanger is generally used for Inter-Coolers, Re-Boilers, Oil Coolers, Strippers, etc.

Note : If Client gives us the Existing/Dummy Shell for the testing purpose then Existing/Dummy Shell is used or else Dummy Shell is fabricated for the same and supplied along with Tube Bundle after carrying out the testing.
