Finned tubes for the highest demands in durability and heat conduction. In a process similar to thread rolling. we roll and extrude a highly thermally conductive material such as aluminum or copper onto a core tube. An endlessly manufactured spiral finned tube is created. The fins are mechanically very resilient (roll hardening) and sit extremely firmly on the core tube. The fin material is covering the surface of the finned tube only and therefore there is no risk of electrostatic cottosion. The profile of the fins are shaped so that optimal heat transfer and lowest possible flow resistance is guaranteed. Extruded finned tubes are produced in bi-metal (with inner tube) and mono-metal (without inner tube) design.

Extruded finned tubes are used for:

  • Gas cooler
  • Gas heater
  • Process cooler
  • Air coolers, cooling towers
  • Condenser
  • Drying kilns
