We offer a complete line of heat exchangers

Form for thermal calculations.


Tube heat exchangers for high pressure
The manufacturing unit at ÖrnalpUnozon are specialists in designing, constructing and manufacturing tube heat exchangers. This type of heat exchangers can withstand extremely high pressure and high temperatures and therefore have many uses. Our specialty is to manufacture tube heat exchangers with dual supplies, such as titanium on the tube side and carbon on the shell side, which are joined together by so-called explosion welding. The thermal calculations required for designing the most advantageous tube heat exchanger for each installation are performed by our heating engineers in HTFS software.

In order to be able to perform this, a number of parameters are required;

  • Temperature program
  • High/low pressure limits
  • Fluid flow capacity
  • Media
  • Size: any restrictions on the length and height (please use the form to the left for faster feedback and suggestions from us) 

ÖrnalpUnozon design shell and tube heat exchangers according to the European standard EN 13445 (PED), the American ASME VIII, the British BS5500 and the German AD-Merkblatt and work in materials like titanium, aluminum, acid proof steel, carbon steel, Hastelloy, SM0254, duplex, super duplex and Tantalum.
