DIABON® Plate Heat Exchangers at a Glance Advantages of our plate heat exchangers in DIABON process equipment graphite Ǡ The special design of the plates means that our graphite plate heat exchangers have a higher heat transfer rate than other graphite heat exchangers Our plate heat exchangers are suitable for corrosive media on both service and product sides The compact construction results in a very low space requirement Counter-current flow allows optimum utilization of the temperature differential By simply changing the number of plates, our heat exchangers can be optimally adapted to...

Our Motto: Compact, Quick, Innovative Its advantage is that it combines the universal corrosion resistance of graphite with the high efficiency of plate heat exchangers. The basis of this new development is the plasticbonded graphite DIABON F100, which was also DIABON F 100 graphite plate pack and LICUFLON® (PTFE)-lined frame plate ® developed by the SGL Group. Another innovation is our modern processing center for the synthetic resin-impregnated graphite brands DIABON NS1 and NS2. This extends our large range of graphite plates. Problem-free servicing Servicing of DIABON plate heat...

Our Design: Solid and Robust 8 The plate pack is secured between two thick steel plates, one fixed and the other movable, by means of tie rods. It is held in line by an upper and a lower stainless steel bar, which are securely fixed to the frame plate. The rear ends of the two guide bars are fixed to a support column. By this means, the pressure plate can be moved freely after releasing the tie rods. This allows unhindered Frame plate (steel) Pressure plate (steel) Support column Guide bars Corrugated plates (DIABON® graphite) End plates (DIABON® graphite) PTFE linings Graphite gaskets Tie...

The design of the DIABON® plate heat exchanger allows pure counter-current flow Advantage The film-type seal can be easily removed when the exchanger is opened; it provides excellent corrosion resistance and an extremely small crosssectional surface for the media to come in contact with. To protect the frame/pressure plates and the nozzles against corrosion, we use LICUFLON® Under the trademarks DIABON F100, NS1 and (PTFE) linings. NS2, a whole range of graphite materials is available. This means that in combination with the The sealing system of the DIABON plate heat different corrugation...

Corrosion Resistance of DIABON® Process Equipment Graphite Carbon and graphite are outstandingly corrosionresistant. Therefore, they are attacked only by strongly electronegative elements such as oxygen at temperatures above 500°C and elemental halogens. Strongly oxidizing acids such as chromic acid can also destroy the carbon. The corrosion resistance is essentially determined by the behavior of the synthetic resin in the case of DIABON NS1 and DIABON NS2 graphite and of the fluoroplastic content in the case of DIABON F100 graphite. If in doubt, corrosion tests can be carried out with...

Corrosion Resistance of DIABON® Process Equipment Graphite DIABON® F100, NS1 and NS2 graphite plates DIABON graphite plate heat exchangers are used mainly in the following media: A reduction in service life is likely with the Hydrochloric acid and HCl gas in all following media, depending on concentration Phosphoric acid in all concentrations Nitrous gases (NOX) in sulfuric acid Other organic and inorganic media. Acids with a high oxidation potential Elemental chlorine and bromine in aqueous solution (e.g. chromic acid, sulfuric acid > 90 %) You will find detailed corrosion tables in our...
