Electronic drain
The electronic drain is a zero loss, electronically operated drain valve, specially designed to drain
oil condensate. A sensor senses the condensate level. If this level exceeds a preset value, the
drain waits for a fixed programmed time, then a solenoid valve is activated and the condensate is
discharged. When all the condensate is discharged, the solenoid valve closes and condensate is
collected again. This way, the loss of air is reduced to a minimum.
If the microcontroller registers a malfunction, the automatic drain valve will automatically change
to alarm mode. This alarm signal can be relayed via a potential-free contact.
The electronic drain is available for 2 operating voltages: 220 V and 115 V. An extra electric
wiring can be foreseen to connect the potential free contacts and an external test button.
Always remove the manual drain or the automatic drain of the filter before installing the
electronic drain.
