IWC offers a wide range of plate heat exchangers and offers a optimal technical solution for almost any application. IWC’s range includes conventional plate heat exchangers, welded and semi welded plate heat exchangers, free flow or wide gap plate heat exchangers as well as spiral heat exchangers, evaporators and condensors.            

Gasketed Plate Heat Exchangers, Condensers and Evaporators
These plate heat exchangers have many applications in industry, in heat recovery processes and air- conditioning. We offer these plate heat exchangers with ordinary, free flow or semi-welded plates.

The plates are tied together in a plate pack with each plate sealed to the next by means of a gasket. Gaskets are supplied in a range of materials specifically selected for the application.

Copper Brazed Heat Exchangers
Brazed plate heat exchangers consist of a number of thin, acid resistant plates, precision stamped and assembled as a unit. The plate pack, assembled with two end plates and connections, is vacuum brazed at extremely high temperatures providing a permanently sealed heat exchanger.

This results in an efficient unit which gives a space and weight saving of up to 80% compared with a tube heat exchanger. These plate heat exchangers are suitable for use with high temperature and pressure. The brazed plate heat exchangers do not contain rubber gaskets and can therefore operate continuously at extreme temperatures from -180°C to 200°C.

The operating pressure can be as high as 30 bar. Some applications where these heat exchangers are an effective solution includes heating and ventilation (for solar heating and air-conditioning units); heat pumps, heat recovery and hydraulic oil units.

Semi and Fully Welded Plate and Shell Heat Exchangers
Thermal efficiency in a welded heat exchanger is comparable to a traditional gasketed plate heat exchanger.

Compared to the shell and tube heat exchangers, these welded units take up significantly less space. The plate and shell heat exchanger works in the same way as an ordinary tubular unit; however, it is more efficient due to use of plates instead of tubes.

The plates are laser welded together to form a plate pack, which is then mounted inside a traditional cylindrical shell. The heat exchanger is produced as an all welded exchanger or with flanges which makes manual cleaning possible.

The all welded heat exchanger is built into a frame with its welded plate pack. These units can operate with temperatures from -100°C to 400°C and with design pressures of up to 40 bar.

These heat exchangers can be used to cool aggressive media and applications include, power plants, petrochemical, pulp and paper, steel and sugar industries.

Spiral Heat Exchangers
This heat exchanger is circular with two spiral channels; each one is a closed chamber allowing for the two products to remain separate while heat exchange occurs.

The flow of these two products is mostly counter current which results in close temperature approach between the two media. A variety of fluids can be circulated through this heat exchanger such as liquids containing solids and fibres, waste water and slurries to name a few.

The heat exchanger is easy to clean and maintain as it has side frames on hinges which open to allow access to the internal spirals.
