Shell and Tube Heat Exchangers

Shell and Tube Heat Exchangers

Shell and Tube Heat Exchangers are designed for external use and manufactured completely from Moldflon-PFA, -ECTFE and- PVDF  as well as from Moldflon-PE or -PP. They are corrosion-free and resistant against almost all chemicals.

For reliable cooling, heating or condensing of pure or high-purity media.

This ensures maximum process safety for the application.

All the welded joints for the flow of inner media are fabricated based on a non-contact IR butt welding prodess which is particular important when using pure and high purity media.
Dead spots where for example bacterial contaminiation may occur, are ruled out by this welding process.

All the IR welds are computer controlled and the welding parameters of these joints are documented. Furthermore, the inside and outside of all the Heat Exchangers are inidividually pressure tested.

Shell and Tube Heat Exchangers from ElringKlinger Engineered Plastics are typically manufactured with one inner and one outer circuit and fabricated in a completely closed welded design.
Alternatively detachable fixed or loose flange joints can be incorporated that open on one or both sides of the Heat exchanger if, for example, replacement of complete tube bundlers or cleaning of the individual tubes is required.
