Competitive Advantage:

  1. We have more than 10,000 square meters workshop, including 10 finning machines, daily extrusion capacity up to 3,000 meters.
  2. The finning machines of Integral Low Fin Tubes are designed and assembled by ourselves and we can offer you finning machines and all accessories etc...
  3. The Integral Low Fins are rolled out of the tube surface to increase the tubes external surface area, without affecting any others dimension.
  4. Low Fins are very useful for tight condensers and exhibits high efficiency of heat transfer.
  5. Economical solutions of heat exchange problems of media with different heat conduction abilities or different current conditions.
  6. High chemical-, thermal- and mechanical resistance, suitable for rough operation conditions.
