BEKO condensate drain BEKOMAT® 6 CO EX

Picture example, BEKOMAT® 6 EX
Empty state:
Condensate drips through the inlet opening 1- and collects in the container 2- The diaphragm valve 5- is closed because the pressure equalization across the valve diaphragm via the pilot line 3- and the solenoid valve 4- 5- takes place. The larger area above the membrane causes a high closing force. The valve seat remains closed without leaks.

Filled state:
If the container 2- is filled with condensate so that the capacitive level sensor 6- reports a signal at the maximum point, the solenoid valve is switched and the area above the valve membrane is vented. The valve membrane lifts off the valve seat 7-, the overpressure in the housing pushes the condensate into the outlet line 8- The valve is closed leak-free before the compressed air escapes. If the condensate drain is disturbed (blocked drain line, defective membrane), the alarm mode is triggered after 60 seconds. The LED flashes, a fault message can be picked up as a potential-free signal via the alarm relay. With Ex devices this is possible via a built-in optocoupler and a switching amplifier. In this state, the solenoid valve is opened for 7.5 seconds every 4 minutes. A BEKOMAT® filled in a pressureless state is automatically alarm-free again under pressure. The drained condensate is now sent to the ÖWAMAT® oil-water separator for disperse condensate for treatment. In the case of stable emulsions, we recommend the BEKOSPLIT® splitting system for almost waste-free processing. Both systems offer legally compliant process technology for treating your compressed air condensate.
