Description of adsorption dryer solenoid
valve control
The inlet valves (Inlet A and B) switch every
120 seconds.
The regeneration valves open variably based
on the real load, e.g. if all the motors are
activated, blowdown is set to 110 s, if two of
the sets of three air pumps are activated (e.g.
M1-6), blowdown is set to 84 s, and if only
three motors are activated, blowdown is set
to 37 s, see the diagram (Fig. 25).
