Heat exchangers

Tube-in-tube heat exchangers

From Ø0.6mm to Ø22mm
Cu-Ni heat exchangers also
Wide range of types of connections

Manufacture of high quality coaxial heat exchangers

We make coaxial heat exchangers and sheathed heat exchangers, either straight or shaped, for the exchange of heat between fluids, gases or liquids flowing inside the two tubes. The ends of the tubing of our exchangers can be processed based on your requirements. We are able to manufacture double-tube heat exchangers with a variety of connections between the tubes, provided with all required accessories.

We also manufacture Cu-Ni coaxial heat exchangers.

Concentric tube heat exchangers fitted with:

  • Capillary tubing
  • Insulating sheathing
  • End fittings
