Project products

We manufacture pipe heat exchangers, pressure tanks, pressure equipment and process tanks to order according to the customer's wishes and needs. Our scope of delivery includes equipment design, strength calculation, if necessary FEM calculation and flow modeling, thermodynamic dimensioning calculation and vibration analyses, structural dimensioning, working drawings and pressure equipment documentation.

Tube heat exchangers

Depending on the purpose of use and conditions, we design and manufacture different types of tube heat exchangers for different media, for demanding processes and conditions. Tube heat exchangers are easy to clean and have low pressure losses.

We manufacture heat exchangers for the following applications, among others: heaters, coolers, condensers, boilers and vaporizers. The structural options we deliver include, among others:

  • U-tube heat exchangers
  • Fixed shell heat exchangers
  • Heat exchangers with floating ends
  • Special applications

The design and manufacture of tube heat exchangers is our special area of expertise. Our know-how provides working heat transfer solutions even for demanding or even special applications. In design and manufacturing, we comply with the requirements of the TEMA (Tubular Exchanger Manufacturer Association) standard. In addition to TEMA, design and manufacturing are implemented using some of the following standards:

  • EN 13445
  • ASME VIII div.1
  • AD-2000 MERKBLATT

In addition to complete heat exchangers, we offer installation, maintenance, and modification services for the entire life cycle of the heat exchanger. We also offer modernization and renovation solutions, in which extensive wholes as well as individual components, such as groups of pipes, chambers or shell parts, are renewed for existing pipe heat exchangers.

We do the design, calculation and thermotechnical dimensioning of the heat exchangers ourselves in accordance with the customer’s requirements. Thermotechnical dimensioning is done on the basis of process parameters, taking into account internal and external loads, flow rates, materials, cleanability and vibrations.

The construction material of the heat exchanger is always selected according to the application. Things that influence the choice are e.g. the risk of corrosion or erosion caused by the contents, pressure and temperature.

The high quality of the production is partially guaranteed by our modern and efficient production. An example of this is semi-automatic TIG orbital welding, which enables the fast, efficient and uniform production of a group of pipes. Our production has an automatic powder arc/MIG-MAG hybrid welding station, which makes it easy to implement larger and more challenging projects. Our personnel is competent, experienced and committed to high quality standards.

In project deliveries, we emphasize punctuality, careful documentation of the project and keeping the customer informed about the progress of the project.

Our customers trust us as a supplier of equipment, experts in strength calculation, design and thermodynamics, implementers of innovative and functional solutions, and professionals in demanding welding. We invest in welding quality management. Our delivery projects are carefully documented, and we pay particular attention to sticking to schedules and keeping the customer informed about the progress of the project.
