13.13 Electronically level-controlled BEKOMAT condensate drain
The electronically level-controlled BEKOMAT condensate drain boasts a special condensate management which
ensures that condensate is discharged safely and without an unnecessary loss of compressed air. This drain has a
condensate collection container in which a capacitive sensor continuously monitors the liquid level. As soon as the
switching level is reached, the capacitive sensor transmits a signal to the electronic control and a membrane solenoid
valve opens to discharge the condensate. The BEKOMAT closes before compressed air emerges.
Note!
These BEKOMAT condensate drains were designed in particular for the operation in a DRYPOINT RA CT
refrigeration dryer. The installation in other compressed-air processing systems or the replacement with
another drain brand can lead to malfunction. The maximum operating pressure (see type plate) must not be
exceeded!
Ensure that the upstream valve is open when the dryer starts operation.
To obtain detailed information regarding drain functions, troubleshooting, maintenance and spare
parts, please read the installation and operating instructions of the BEKOMAT condensate drain.
