Function description
The dryer dries the compressed air supplied by the compressor and makes it available for
industrial use.
Upstream lters clean the compressed air and remove dust, dirt, oil, and water droplets, before the compressed air reaches the dryer. Thus, an upstream lter is also used for extending
the service life of the drying agent.
Downstream lters clean the compressed air from drying agent abrasions, before it is fed into
the compressed air system.
The two chambers of the hollow section vessel contain an extremely porous drying agent by
means of which humidity is removed from the compressed air and stored just as in a sponge.
The stored humidity is then removed again from the drying agent and re-introduced into the
ambient environment.
To this end, the two chambers alternate between different operating modes. Whilst in one
vessel, compressed air is de-humidi ed (adsorption), in the other vessel the humid drying
agent is prepared for another charge (regeneration). These two states, which run in parallel
during compressed air preparation, are described below.
14 K-MT 1-4/D3
EN | User Manual Technical product description
Adsorption
Via a compressor, humid compressed air is
supplied to the upstream lter. From here, the
compressed air ows upwards through the
absorption chamber, which is pressurised. In
so doing, the drying agent dehumidi es the air.
The dry compressed air is supplied to the pipe
network via the downstream lter.
Here, adsorption is shown in the left
vessel.
Regeneration (running in parallel to the adsorption)
At the same time the other chamber is prepared for a renewed take-up of humidity. This
process is called regeneration.
The regeneration is subdivided into three phases: expansion, dehumidi cation, and
pressure build-up. With the dewpoint-sensing control option, the regeneration phase is
followed by a standby phase.
Expansion phase
During the expansion phase the pressure in the
right chamber is released via the muf er down
to ambient pressure within just a few seconds.
The out ow of the compressed air becomes
noticeable due to a sudden powerful ow noise
at the muf er.
Dehumidifi cation phase
Prior to being released into the pipe network,
dried compressed air is bled by means of an
ori ce plate. This separate regeneration air ow
is fed through the depressurised chamber. The
humidity stored in the drying agent is taken up
by the air ow and expelled into atmosphere via
the muf er.
Here, regeneration is shown in the right
vessel.
