Modular heat exchangers are used for the cooling or heating of
aggressive liquids in containers.

They are completely manufactured from the Moldflon™-PVDF, -PP and -PE materials: whereby a further area of use is covered regarding resistance to chemicals and temperatures.
These heat exchangers are manufactured from individual hose modules and standardized components. The hose modules consist of hose spirals, which are inserted into rails and jig-welded with specially developed hose connections to specially constructed welding and assembling devices. These hose modules are then fitted to a rigid frame, into which the medium´s supply and discharge pipelines are integrated.

The modular rails are screwed to the frame and the hose connections are welded into the frame´s parts which conduct the media. The most varied dimensions and exchange surfaces are thus realizable in a compact and very rigid construction by means of the modular construction.
