All-Welded Plates (Hybrid)
 |
Since 1981, the APV HYBRID PLATE HEAT EXCHANGER has been firmly established in the industry. The broad range of possible construction forms for the hybrid system allows for the best possible solution to be found for given thermal, physical and geometrical conditions. The fully welded APV HYBRID PLATE HEAT EXCHANGER ensures that different media are safely kept separate- even when higher pressures and temperatures are applied. This means that there is a wider range of possible applications than where the gasketed plate heat exchangers can be applied. THE APV HYBRID proves superior in any respect when compared to shell & tube heat exchangers with the usual construction design and identical conditions for process engineering. Its compact design allows a heating surface density of 250 m²/m³. The special construction of the flow pattern ensures that the heat transfer for gases as well as for liquids is extremely enhanced. A further advantage in comparison with shell & tube heat exchangers is the high economic efficiency of the APV HYBRID HEAT EXCHANGER. The use of less material means considerable cost reduction potential when high-grade alloys are required. |

FunctionalityThe APV Hybrid plate heat exchanger design has no dead spots and provides very efficient heat transfer at low pressure drop values to ensure that it functions at a very accurate temperature. The plate side flow and the tube side flow are arranged in cross flow configuration in one or multiple passes over the plates. The plate pattern forms elliptical tube channels on the tube flow side and wave flow passage on the plate side. The depth of the plate pressure can be increased in order to allow greater flow rates or reduced pressure drop for the passage of larger particles. This functionality provides an optimal design for many process requirements and is achieved by enlarging the diameters of the elliptical tube channels, while maintaining the plate distance on the plate flow side. It is also possible to achieve a wide-gap condition on the plate flow side by welding the plates further apart. The APV Hybrid plate heat exchanger can be designed for a pressure range from full vacuum to 60 bar. Like all our products, the APV Hybrid plate heat exchanger conforms with the quality assurance norm ISO 9000.
