Empty state:
Condensate trickles through the inlet opening and collects in the container (2). The diaphragm valve is closed, since the pilot supply line (3) and the solenoid valve (4) ensure pressure compensation above the valve diaphragm (5). The larger surface area above the diaphragm results in a high closing force, so that the valve seat is tight and leak proof.
Filled state:
When the container (2) has filled with condensate and the capacitive level sensor (6) signals at the maximum point, the solenoid valve is energized and the area above the valve diaphragm is vented. The valve diaphragm lifts off the valve seat (7), and the pressure in the housing forces the condensate into the discharge pipe (8).

The BEKOMAT® electronic system now calculates the dis-charge rate down to the minimum point and uses this figure to determine the exact valve opening period required. The valve will again be fully closed and leak proof before any compressed air can escape.
Should the condensate discharge fail to function properly (blocked discharge pipe, faulty diaphragm), the device will change to the alarm mode after 60 seconds. In this case, the red LED flashes and, if desired, the alarm signal is relayed via a potential-free contact. While in the alarm mode, the solenoid valve will open every 4 minutes for a period of 7.5 seconds. This ensures that a BEKOMAT® unit filled in an unpressurized state will, under pressure, automatically revert to normal operating conditions and thus clear the alarm.
From the BEKOMAT® the condensate can flow for treatment into the OWAMAT® or QWIK-PURE® oil-water separator which is designed to deal with condensate contaminated with free and dispersed non-emulsified or emulsified (QWIK-PURE®only) oil. In the case of stable emulsions, our BEKOSPLIT® emulsion splitting plant will clean up the condensate leaving only a minimum of waste for disposal. Either system will help your company to conform to the legal requirements concerning the treatment & discharge of compressed air condensate.
