Tubular heat exchanger Hybrid

liquid/liquidgas/liquidgas/gas

The hybrid heat exchanger is a special plate heat exchanger covering nearly all industrial applications. It is suitable for chemistry, petro chemistry, sugar-, food- and pharmaindustry, and many more. This heat exchanger unites the conventional tubular-, plate- and spiral heat exchangers and can be made to fit almost all thermal conditions. Furthermore it can also be built as an evaporator or condenser, with the compact construction style (250m 2/m 3) resulting in a low weight. The fully-welded construction has no soldering points or extensive gaskets, therefore strains for the heat exchangers result only from the surrounding environment. Hybrid plate heat exchangers have a high heat transfer efficiency at compact measurements and low pressure loss. They are mainly used in evaporation- and condensation-processes. Inside the hybrid devices tubular flow cross-sections without any dead zones direct the flow with regular transverse embossments. They achieve a considerable increase in heat transfer without noticeably raising the pressure decrease. At the same time the transverse embossments cause neighbouring cross-sections to support each other, thereby bracing the whole structure (which will withstand pressures up to 60 bar). The temperature limits are -200°C up to +900°C. The heat transfer is achieved via the 0.4 to 1.0 mm wall of the exchanging element, which is designed as the primary heating surface. The use of corrosion-resistant material is possible without respect to its thermal conductivity, providing it can be bent and welded.
