Electronically level controlled condensate drain
Electronic level-controlled steam traps are one type of steam traps , and serve to dehydration of water vapor , compressed air and gases .
function
Electronically level-controlled condensate drains have a membrane that is closed by the system pressure. During operation, a capacitive sensor permanently records the fill level of the condensate container. When the condensate reaches the upper level, the integrated electronic control discharges the condensate. To do this, a solenoid valve is activated, which reduces the pressure on the membrane. This opens the membrane and drains the condensate. If the condensate reaches the lower level, the solenoid valve directs the system pressure back to the membrane, which then closes again. During the draining process, only condensate and no compressed air escapes.
Applications
Due to their reliable and cost-efficient operation, electronically level-controlled condensate drains are used in a large number of industries and areas of application. This includes, for example, the mechanical engineering , electrical and automotive industries or food and beverage processing. The steam traps are also used in areas with particularly high demands and compressed air quality. These include, for example, the pharmaceutical industry, medical technology and the chemical industry .
Others
In a special design, electronically level-controlled condensate drains can also be used in negative pressure systems.
