Double tube heat exchangers

Spiral or U-shaped tube-in-tube design with thermodynamically ideal counterflow - also for media with high viscosity and high solids content.

  • Counterflow principle for high thermal efficiency
  • Large flow cross-sections for viscous, solids-laden or contaminated media
  • Modular, demountable and expandable, or fully welded
  • Modular version: every heat transfer surface can be cleaned, inner or outer tube replaceable without welding

Material Stainless steel

The double tube heat exchanger is based on a tube-in-tube design that delivers high efficiency through the thermodynamically ideal counterflow principle. Large flow cross-sections allow the use of media with high viscosity and high solids or dirt content.

Designs

AWS-Technik continuously develops this proven technology and supplies double tube heat exchangers in spiral or U-shaped designs. The range extends from spirally wound units with tube lengths of up to 70 metres to high-polish designs with demanding surface quality requirements.

Modular or fully welded construction

Alongside fully welded versions, our demountable, modular and expandable heat exchangers are a speciality: inner and outer tubes can be removed so that all heat transfer surfaces can be cleaned. In case of heavy fouling or advanced corrosion, the inner or outer tube can be replaced without welding. We also supply standard brackets for all mounting locations, for example ceiling, wall or floor.

Frequently asked questions

Which construction options are available?

Modular and expandable, or fully welded versions are available. In the demountable, modular double tube heat exchanger both inner and outer tube can be removed. All heat transfer surfaces can be cleaned, and in case of heavy fouling or advanced corrosion the affected tube can be replaced without any welding.

Which media is the double tube heat exchanger suitable for?

Thanks to its large flow cross-sections it is particularly suitable for media with high viscosity and high solids or dirt content.

Which mounting options are available?

We offer standard brackets for all mounting locations - for example ceiling, wall or floor.
