welded – redrawn – polished – cut – bend – worked – pre-fabricated – special shaped

in polymers extrusion encapsulated

• Laser welding fin onto tube without filler material
• Crevice free welding -> 100% gap free!
  no crevice corrosion
• Small heat affected zone
  no material deformation
  high corrosion resistance even with very aggressive media
• Laser welding under protective atmosphere
  no weld seam impurity
• 100% welding between fin and tube
  optimal heat transfer
• Long service life at nearly 100% performance
• In straight compact design as spiral coil, U-bent, meander form with reduced weight
• Intermediate sections with different fin height and even down folding of fins possible

With typical dimensions of:

• Plain tube outside diameter:             8.0 mm – 74.0 mm
• Fin height:                                         5.0 mm – 20.0 mm
• Fin outside diameter:                      18.0 mm – 84.0 mm
• Fin pitch:                                    5 – 13 fins per inch (fpi)
• Maximum tube length:                                        12.0 m
