They are hermetically sealedand temperaturewithout gaskets and can therefore handle extreme operating pressures and temperatures.Compact low-weight designDuring assembly every other plate is rotated by 180 degrees in the plane to produce twoseparate flow channels in which the products involved in heat transfer flow in oppositedirections. The innovative plate patterns generate a highly turbulent flow allowingefficient heat transfer even at low volumetric flows. This prevents any soiling of the heatexchanger and non-contact zones are completely excluded.As just about the all heat exchanger plate is used as a heat transfer surface, brazed plateheat exchangers are extremely space-saving and cost-effective.[3]

Always the best solutionFrom all-rounders to specialistsCopper is the most common brazing material used in brazed plate heat exchangers. It provides the highest processing quality andpressure strength combined with an excellent cost-performance ratio. Copper is resistant towards most media and is therefore always thematerial of choice, when suitable. It can also be combined with a number of stainless steel plate materials.GBS Series – the all-rounderIdeally suited for applications of any size –GBH Series – keeping cool, evenunder high pressureGML Series – for safe CO2applicationspressure-resistant up to 30 bars and upThis series is designed for pressures of upThe multi-layer technology used is basedto 200 C!

Where the reliability of copper is not sufficient in ultrapure water applications (deionate, etc.) as well as with corrosive media, plantoperators prefer nickel as the brazing material. In contrast to copper-plated brazed plate heat exchangers, the nickel-plated versions havea silver-coloured surface and offer all of the advantages expected from brazed plate heat exchangers. But not every nickel brazing is thesame: Only around 75% is made of pure nickel, the remaining 25% is our secret – and your benefit.GNS Series – stable towardscorrosive mediaWhenever the strength of copper isnot enough – in direct comparison withcopper-brazedplateheatexchangersincreased stability against corrosive mediasuch as ammonia, sulphides and sulphates.Laser coolingApplications using deionised waterAmmonia systemsDemineralised water and corrosiveliquidsHeating drinking water without non-ferrous metalsGG Series – Efficient, compact and safeThe GG Series is a convincing solution when it comes to the specialrequirements involved in the heating of drinking water. It combines theadvantages of our brazed and gasketed plate heat exchangers.

For specialist applicationsSpecial designsDW – Double wallThe DW Series is an extremely reliable and mix-proof compact double-wall design. Itoffers double reliability that your media always remain separate from each other evenunder the highest demands. Mixing of the media is prevented in the case of an internalrupture. Brazing material: copperHP – High-pressure frameThe HP Series uses an external pressure-bearing frame to achieve higher pressures.Condensers and economizers for ammonia applications in conjunction with nickel braze.Brazing material: nickelTD – True-Dual heat exchangerTrue-Dual – the twin-circuit evaporator or condenser is a synonym for constantly highefficiency. The TD reliably provides this optimum performance even when operated usingonly one refrigerating circuit. It comprises two independent refrigeration circuits anda water/brine circuit. Brazing material: copperXCR – eXtended Corrosion ResistantOur XCR models feature high corrosion resistance to chlorine-loaded media. The platematerial used is high-quality stainless steel, SMO 254 (1.4547). Brazing material: copperor nickelAP – Air Plate compressed air drierThe AP Series of plate heat exchangers was developed for efficient refrigeration drying ofindustrial gases. A range of different models and features allows a system configurationwith either separate or integrated condensate removal as well as heat recovery in allstandard sizes. Brazing material: copperOC – Oil-CoolerSpecially developed plate heat exchanger for oil and hydraulic cooling. The OC Seriesoffers reinforced flange connector plates, either with SAE standard connections orinternal threads. Brazing material: copper[6]www.gea.com

Larger contact points result in stronger brazing pointsbetween the plates and guarantee high pressure resistance of the equipment.Full-Flow System The Full-Flow System was developed to prevent freezing of the flow channels andtherefore to minimise failures of brazed plate heat exchangers used as evaporators inrefrigeration systems. It guarantees optimum flow around the nozzles and is veryeffective in preventing port freezing.Safety Chamber Our patented Safety Chamber is the ultimate feature for large brazed plate heatexchangers. Encapsulated contact points around the ports take up the forces. Even whenthese contact points are overloaded and the material fractures, there is still no penetrationto the other process medium – representing maximum process reliability for plantoperators.AE – Advanced EvaporatorThe patented refrigerant distribution system was specially developed for evaporatorapplications. It provides precise distribution of refrigerant to the channels, guaranteeingmaximum evaporator performance. It is fully integrated into the refrigerant inlet of theheat exchanger and functions with both dry and flooded evaporation. Brazing material:copper or nickel[7]
