PTFE is the only viable option for a heat exchanger assembly. With the proper fabrication and right materials,
it offers a very effective, durable, and versatile solution for all industries where heat exchangers are needed.
We also deliver fluoroplastic heat exchangers. These heat exchangers are made of fluoroplastics such as PTFE, FEP an PFA. Fluoroplastics are fully resistant against corrosive liquids and have very good non-stick properties. This means there is no building up of pollution and it reduces fouling and scaling. Fluoroplastics are pure and contain no softeners or plasticisers and are therefore very suitable for handling ultra-high-pure (UHP) applications in the semi-conductor industry.
All types of fluoroplastic heat exchanger units feature a proven unique honeycomb structure. The tubes are integrated in the pipe sheet which provides a lightweight compact bundle design. This ensures a leak free flow of the process liquids. Teflon heat exchangers are almost maintenance free and have a very long lifetime.
Shell and Tube heat exchangers are single pass, typically countercurrent flow units designed for heating, cooling and condensing applications. Units incorporate flexible fluoropolymer tube bundles joined together to form integral honeycomb tube sheets and are available with FEP or Q-Series tubing with PTFE lined heads. Standard shell construction is carbon steel. Other shell materials available on request. The heat exchangers are ASME coded and equipped with nozzles according to ANSI or DIN. For a better heat transfer performance the heat exchangers can be equipped with PFA/Graphite tubes (Q-series).
Coils are widely used in the metal finishing and chemical processing industries, and are especially suited to batch and continuous steel pickling applications. The inherent non-stick characteristics of Teflon® resist corrosion and fouling, extend heat exchanger service life, and improve value-in-use through savings in plant maintenance costs.
Tube bundle heat exchangers are used for heating and cooling of corrosive fluids in a wide range of processes and applications. The well-known non-stick characteristics of fluoropolymer resist corrosion and reduce fouling. Reactor Coils are designed for immersion directly into the process vessel, and are most efficient when agitated in the process solution. During agitation, the flexing action of the coils helps reduce fouling and dislodges deposits that may have formed. This and other unique design features make the Reactor Coil ideal for crystallizer applications.
Minicoils heat exchangers fully made of fluoroplastics are suitable for small pickling baths. The inherently high electrical resistance also helps prevent short circuits and stray currents in plating baths.
