Product Introduction
Thermowave plate heat exchangers
Thermowave plate heat exchangers are characterised by the outstanding efficiency in high pressure applications with natural refrigerants,such as CO2 and NH3 .Thermowave products consist of laser welded modules and can be used for any industrial cooling processes requiring low evaporating temperatures.
Special gaskets, developed for this very application, are not only resis-tant against the media flowing in the heat exchanger, but also guarantee the tightness of the plate heat exchanger and thus the safety of your plant.Thanks to its flexible construction taking care of pressure and tempera-ture changes, the Thermowave can be used for applications with a big demand of heat recovery and energy saving. Thus, a new field of applica-tion was opened for special process conditions, also taking into account environmental safety requirements.

Working principle
Two heat exchanger plates are welded together to a gastight module by means of laser technology. By doing this,a flow channel for the aggressive (or the gasket attacking medium) is built, which is hermetically closed to the outside. Only two ring gaskets, made between two welded modules, are in contact with the aggressive medium.
The other flow channel for the non-aggressive medium is sealed by various elastomer gaskets, depending on the individual application. The gaskets are normally fixed without the need for glue but are also available in the glued-
on-version.
Interleakage between the two media is prevented by a double weld, and a double ring gasket in the port holes.If a leakage occurs for any reason, the leak will be external and easily detected. In spite of the use of welded modules, the proven flexibility of plate heat exchangers is maintained. By adding or changing modules, the heat exchanger capacity can be adjusted to the individual requirements.
The laser welded modules can be used for temperatures from -45° C to +160° C, and for pressures up to 50 bar.
Description of plate heat exchanger
Thermowave plate heat exchangers consist of a number of laser welded modules. The module pack is mounted between a fixed and a movable pressure plate, positioned by an lower and upper carrying bar, and compressed by several tightening bolts. Laser welded modules with various patterns are available for a wide range of applications.
The media can pass the heat exchanger either in cocurrent or countercurrent flow. Depending on the operating condi
tions, medium and temperature-resistant gaskets gaskets are clipped on.The laser welded module, forms a hermetically sealed flow channel to the outside. The transition from one module to another is sealed by a ring gasket made of special materials.
