TRUE ZERO AIR LOSS:
Exclusive operating principle guarantees maximum energy savings
Integrated sieve keeps the drain operational and unaffected by dirt, and eliminates the need for a Y-strainer and extra maintenance
Reduce overall time and costs
Ensures intelligent operation at all times and is safe for all condensate types
Visual status indication is given on the drain and can be wired for remote access
The condensate trickles through the inlet opening  and collects in the container . Initially, the valve is closed as, via the pilot supply line  and the solenoid valve , pressure differential above the membrane  is effected. The larger surface area above the membrane results in a high closing force. The membrane seat remains closed and leak-proof. When the container is filled with condensate, so that the capacitive level sensor  gets a signal at the maximum point, the solenoid valve switches over and the area above the membrane is vented. As a result of the decreasing pressure above the membrane, the membrane lifts off the membrane seat  and the overpressure in the housing forces the condensate into the discharge pipe .
