Option: No loss condensate drain (Zero Drain)
Zero Drain is the new electronic drain discharger applicable to any
compressed air systems. It eliminates the condensate without wasting
compressed air.
Electronic drain discharge starts automatically, without the need of any
adjustment. The condensate discharge occurs to the use of an electronic
sensor, which detects the amount of condensate in the integrated water
collecting tank. The level sensor drives start and duration of the drainage,
so preventing any wasting of compressed air.
At the end of installation, put the system under pressure and push the
TEST key repeatedly to eliminate the air bubbles contained in the
discharger inlet fittings.
The Zero Drain unit is equipped with a remote alarm connection (dry
contact, trigged when the drain is in alarm for more than 30 seconds): see
terminal block diagrams (attachment B) for futher details.

Zero Drain is equipped with Service Unit, which is recommended to be changed every year to ensure proper working conditions
