Plate heat exchangers are used to transfer heat or cold between two liquids. They are made of embossed pairs of interconnected plates which have two channels inside. A warm medium flows through one channel and through the other channel, a cold. The two media flow in countercurrent flow.
Because of the use of different media, we offer solutions for various industries. Our plate heat exchangers are suitable for cooling, heating, condensation, evaporation, ventilation and refrigeration applications. Design and construction of the apparatuses are bespoken and completed with a constant eye for technical competence.
The product portfolio of thermowave includes gasketed and module welded plate heat exchangers. We focus on applications in these areas:
Refrigeration
Food and Beverage Industry
HVAC
Process Technology and
Power
We are the specialist for phase-change! When evaporating and condensing, our leading modular welded plate heat exchangers are used in the area of high pressure applications and applications with natural refrigerants.
Gasketed plate heat exchangers

With gasketed plate heat exchangers, the connection between the plates is accomplished with elastomers. The selection of the gasket is ideally suited to the media which will be used.
Gasketed plate heat exchangers are convincing due to their great flexibility. At any time, they can be opened, cleaned and adjusted in their performance. If the media changes it is also possible to provide the PHE with other gaskets and plate materials. Another advantage is the high resistance of the gaskets used against the flowing media in the apparatus.
Gasketed plate apparatuses are modular, very flexible and therefore very adaptable heat exchangers. They are widely used in commerce and industry.
Module welded plate heat exchangers

Here, the heat exchanger plates are gas-tight welded together by laser. The advantage is that the laser welds withstand high static pressures and tolerate even common pressures and temperature changes.
Module welded plate heat exchangers are often then the best solution when it comes to applications with critical process parameters such as high labor and gasket pressures. In addition, the module welded construction has proved itself successful wherever changing parameters require a particular flexibility, such as in fast-growing plants that require a cost-effective adaptation of existing system components.
We are able to claim and guarantee first class service beginning with the optimized, customized design to any needed repairs and maintenance.
Additional product and investment security for all thermoline apparatuses is obtained through our total quality management – the development, design, manufacture and sales of thermowave products are certified according to EN ISO 9001:2000, PED 97/23, and ASME.
