The UFM-D’s are compressed air zeroloss, electronically controlled condensate drains.The large internal cross-sections fordraining ensure reliable operation evenwhen dealing with dirty, particle polluted condensate: Less downtime, less trouble and more safety for the application – especially in direct comparison with
time- or float controlled drains. Additionally the condensate becomes
less emulsified – when compared with time controlled solenoid valves which
spray/ atomise the condensate. Less emulsification results in better function
of oil/ water separators: longer compliance with legal discharge limits, less
running costs! As there is no air-loss whilst purging these drains work silent – a very important feature when this drain is installed within a working area!
The electronic control of the drain monitors the proper operation continuously.
Automatic malfunction routines and a potential free contact for remote control ensures safe operation at all times. You can react to malfunctions before they are obvious by condensate water in the compressed air line at the point of use!

Applications:
Compressed air zero-loss draining of condensate at:
• compressors
• aftercoolers
• receiver-vessels
• pre- and after-filters of fridge dryers
• pre-filters of adsorption dryers
• condensate- and oil-removal filters
• pipe bends

Pneumatic level-controlled condensate drain, suitable for the operation in explosion-endangered areas.
Function:

Condensate drips through the intake port (1) and is collected in vessel (2). The control valve (4) is closed and the surge chamber (5) is vented.
The Operation pressure in vessel (2) presses the diaphragm (8) at its seat and thus separates the condensate channel at the pressure side from the other one at the exit side (10).

if much condensate has been collected in the vessel, the fl oat is lifted and compressed air can get into the surge chamber (5) over the control valve
(4). The diaphragm (6) is pressed to the right hand side and opens the diaphragm (8) by means of the piston (7). Now the condensate can drain to the exit (11) over channel (9) and (10). If the fl oat (3) moves down with the condensate level so far that the control valve closes again, the surge chamber is vented over nozzle (12). The diaphragm (6) as well as the diaphragm (8) over the piston (7) come back to their starting position, so that the drainage is closed again. A testing of the function of the outlet valve can be done by means of the hand valve (13).
