11.Competitive Advantage:
■ We have more than 10,000 square meters workshop, including 10 finning machines, daily extrusion capacity up to 3,000 meters.
■ 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...
■ The Integral Low Fins are rolled out of the tube surface to increase the tubes external surface area, without affecting any others dimension.
■ Low Fins are very useful for tight condensers and exhibits high efficiency of heat transfer.
■ Economical solutions of heat exchange problems of media with different heat conduction abilities or different current conditions.
■ High chemical-, thermal- and mechanical resistance, suitable for rough operation conditions.
