Regulating the DRL 6-2 integrated dryer
Pressure dew point
regulation
The DL dryer can be operated permanently under partial load, caused by re-
duced compressed air flow or a lower compressed air inlet temperature, with
an output in the range 0 – 100%.
Condensate drainage
Fig. 3.5: Condensate drain
When the level sensor signals that the condensate container is full, a valve is
opened and the condensate is forced through the drain pipe by the operating
pressure.
The condensate drain electronics ensure that the outlet opening is closed
before the compressed air can escape.
If the condensate outlet is faulty, the condensate drain switches to Timer mode
and the valve opens in cycles (approx. every five seconds per minute) to rem-
edy the fault automatically. For more information, please refer to the separate
operating instructions for the condensate drain.
The level-controlled condensate
drain automatically drains conden-
sate from the DL dryer.
