Technical Description

7.14 Electronic Drainer (Optional)

Instead of the usual drain system (a solenoid valve controlled by means of electronic instrument); an electronic
level controlled drainer can be installed as option. This drainer consists of a condensate accumulator where a
capacitive sensor continuously checking liquid level is placed: as soon as the accumulator is filled, the sensor
passes a signal to the electronic control and a diaphragm solenoid valve will open to discharge the condensate.
For a complete condensate discharge the valve opening time will be adjusted exactly for each single drain
operation. No condensate strainers are installed. No adjusting is required. A service valve is installed before
the electronic drain in order to make check and maintenance easily. At dryer start-up verify that this valve
is open.
