Manufacturing and advantages as described for type N but with higher fins. The fins are rolled out of the wall of the plain tube. Tube and fin are consisting of one piece.

Materials:

Carbon Steel, Low Alloy Steel,Stainless Steel, Nickel, Nickel-Copper, Nickel-Chrom-Iron, Copper Alloy, Aluminium Alloys, Titanium

Fields of application:

Water heating, solar technics, oil-cooling, heat-exchangers, condensers, evaporators.

Manufacturing process:

The fins are rolled out of the wall of the plain tube as type N,but higher fins.The fins are rolled out of the wall of the plain tube by use of a pass roller. Tube and fin consist of same piece.

Advantages:

Economical solution of heatexchange problems of media with different heat conduction abilities or different current conditions. High chemical-, thermal- and mechanical resistance, suitable for rough working conditions.
