How the dehumidifier works
The A15 ES is an adsorption dehumidifier of four-hole type meaning that it has two fans and two
entirely separated air flows. It is also provided with stubs on all four inlets and outlets for easy
ducting of air flows and full flexibility in installation, allowing the machine to be positioned either
inside or outside the space to be dried. Similarly, the easy ducting also allows for the regeneration air
to be sourced from the most appropriate space, considering both the pressure balance as well as the
energy consumption.
The principals of the dehumidification process implemented with the A15 ES can be described as
follows:
Process air to be dried is drawn into the machine via the process inlet and continues
through the process air filter, removing dust and particles. In the next step, it passes
through the rotor and is put in contact with the silica gel that adsorbs moisture and
dries the air.
In the final step, the dry air passes through the process fan and is pushed out through
the dry air outlet, ready to be distributed to where it is needed.
In parallel with the drying process, to prevent the rotor from being saturated at which point the
dehumidification would have stopped, the rotor is continuously regenerated through use of a
completely separated air flow that functions as follows:
Regeneration air is drawn into the machine through the regeneration air inlet and
proceeds through a filter. The now cleaned air flow proceeds through a small segment
of the rotor, a segment that was just regenerated and thus still heated. The
regeneration air passing this segment will thus recycle portions of the already spent
regeneration energy, increasing the temperature of the new regeneration air while
cooling the rotor.
The pre-heated regeneration air continues through the regeneration heaters,
increasing its temperature and thus its regeneration power, before it again passes the
rotor in the regeneration zone causing the rotor to release adsorbed moisture, thus
regenerating it and making it capable of adsorb new moisture.
The now humid air, normally referred to as wet air, is drawn through the regeneration
fan and pushed out through the wet air outlet.
