Regeneration (completed in parallel with adsorption)
The regeneration is subdivided into four phas-
es: expansion, heating, cooling and pressure
build-up.
With the dewpoint-sensing control option, the
regeneration phase is followed by a standby
phase..
The following fi gures show the regeneration
phases (here: regeneration in right vessel)
Expansion phase (duration: some minutes)
The pressure in the right vessel is released
through the expansion valve until the ambient
pressure is reached. The escaping of the com-
pressed air is thereby audible at the silencer as
a low hum.
Expansion phase
Heating phase (duration: several hours)
A vacuum pump sucks ambient air through the
heater* to the vessel to be regenerated. The
air is thereby heated by the heater. The warm
air subsequently fl ows through the humid
desiccant, removing the water contained in the
agent, which is fed out in the form of steam
together with the air through the piping.
* This can be either a steam or an electrical
heater, but also a combination of both heater
types
