High finned tubes

Used in condensing boilers, aluminium finned tubes meet the highest demands for heat conductivity, low specific weight and formability. Due to its flexibility and at the same time its excellent shape stability these form the basis for high-quality heat exchanger solutions in bundles or coiled design.

Product characteristics

  • heat exchanger tubes with outer and / or inner fins
  • materials: aluminium alloys, stainless steel / aluminium alloys (dual metal design)
  • dimensions: customer-specified from > 30 mm to > 55 mm fin diameter
  • available in: straight lengths or as requested as usable heat exchangers
  • product information for downloading:
    Brochure GEWA-H and GEWA-HB (PDF, 0.2 MB)

Benefits

  • option of compact design via optimised heat transfer surfaces
  • high heat conductivity of aluminium materials
  • tried-and-tested corrosion resistance of aluminium materials against water containing acids and chlorides
  • fast heating up times due to low inertia of wall and fin
  • flexible shaping possible for coiled / bowed bodies
