Product Description

Extruded Heat Exchanger Extruded Copper Low Finned Tubes


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 us makes these products perfect for a broad scope of applications in the refrigeration and air conditioning industry, for oil/gas coolers in machinery and plant engineering, and for intermediate vapor superheaters in process engineering.



Your benefits at a glance

  • Reliable solutions for diverse application areas
  • Larger heat transfer surface compared to smooth tubes
  • Savings in material thanks to reduced tube length
  • Fill level reductions on account of increased efficiency

General Low Fin Tubes Production Capacity  Specifications of Low Fin Tubes('N' Fins)

Finning Facility: 10 finning machines;
Daily capacity up to 3000 meters;
Tube OD: 12.7 mm~25.4mm
Tube Length: No Limit
Fin Height: 1.2 mm ~2.77mm
Fin Thickness: appr. 0.3mm
Fin Pitch: 30 FPI /28 FPI/ 26 FPI/ 36 FPI /43 FPI

Manufacturing process:
The fins are rolled out of outer wall of the plain tubes by a pass roller. Tubes and fins are in same piece tube. We call it “N” fin type.
Delivery of Low Fin Tubes
We can provide the integral low fin tubes with un-finned section gaps( 5mm Min.) in the middle of core tube OR bent with designed Bend Radius.
Quality Test:
The integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO            tests in order to verify design specifications.
 Acceptance ceritia: 
Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish.
The desiccants are put into the each package for continental transportation.
​The Integral Low Finned Tubes find the preference in the following industrial sectors:

  1. Heating systems
  2. Ventilation systems
  3. Refrigeration and climate control systems
  4. Mechanical engineering
  5. Automotive manufacturing
  6. Chemicals and pertrochemical and power plant technology
