Heat exchanger, type VEV-Ex


Heat exchangers (heat exchangers) heat gas for a subsequent system requirement or to counteract the Joule-Thomson effect. For example, For example by pressure reduction in a gas-pressure control. Heat exchangers can also be determined in the reverse mode of operation as coolers. The design is carried out as a steel welded construction in vertical or horizontal design.


Heat exchangers VEV (vertical) or VEV-L (horizontal) operate as standard counter-flow Unlike normal shell-and-tube heat exchangers VEV/VEV-L in single-tube design, the VEV-Ex electric preheaters have an integrated heating element which is immersed in a water bath. The gas is indirectly heated via the water. VEV-Ex type heat exchangers are small compact heat exchangers for low flow rates and a maximum power of <15KW. The gas flows through the coil, which is guided around the heating element. Level limit switch, thermostat and temperature limiter (water side), thermometer, pressure gauge, safety valve are supplied.

Quality management
