Transporting and installing the dryer
Requirements for the installation site
The conditions at the installation site have a large influence on the functional
capability of the dryer and the service life of the drying agent. In order to ensure a
mode of operation, which is as continuous as possible, and low maintenance, the
installation site must meet the following requirements:
The installation site must be located within a building. Protect the dryer against
moisture.
The ambient temperature must not drop below +1,5 °C (34,7 °F).
Heed the dryer’s noise emission when selecting the installation location.
The installation area must be level, firm and vibration-proof. It must have the
necessary carrying capacity for the weight of the dryer. The weight of the dryer
is specified in the technical data section of the annex.

The dryer should be installed with
sufficient spacing at the top, sides, and
rear, in order to be able to carry out
maintenance work and change the
drying agent without any hindrances
(see figure).
Necessary spacing at the top and sides
= min. 1 m
If in doubt, the installation site must be inspected by specialists. If you have any
queries in this regard, please contact the manufacturer (for details see page 8).
Transportation using lifting or forklift trucks
Warning against damage to property!
The dryer is delivered standing on its side on a transportation pallet. Top

K-MT10-95_EN_02 19
Function description
The dryer dries the compressed air supplied by the compressor and makes it
available for industrial use.
Upstream filters clean the compressed air and remove dust, dirt, oil, and water
droplets, before the compressed air reaches the dryer. Thus, an upstream filter is
also used for extending the service life of the drying agent.
Downstream filters clean the compressed air from drying agent abrasions, before
it is fed into the compressed air system.
The two vessels 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 vessels alternate between different operating modes. Whilst
in one vessel, compressed air is de-humidified (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.
Adsorption
Via a compressor, humid compressed air is
supplied to the upstream filter. From here, the
compressed air flows upwards through the
absorption vessel, which is pressurised. In so
doing, the drying agent dehumidifies the air. The
dry compressed air is supplied to the pipe
network via the downstream filter.
Here, adsorption is shown in the
left vessel.
Regeneration (running in parallel to the adsorption)
At the same time the other vessel is prepared for a renewed take-up of humidity.
This process is called regeneration.
The regeneration is subdivided into three phases: expansion, dehumidification,
and pressure build-up.
With the dewpoint-sensing control option, the regeneration phase is followed by a
standby phase.

20 K-MT10-95_EN_02
Expansion phase
During the expansion phase the pressure in the
right vessel is released via the muffler down to
ambient pressure within just a few seconds. The
outflow of the compressed air becomes
noticeable due to
a sudden powerful flow noise at
the muffler.
Dehumidification phase
Prior to being released into the pipe network,
dried compressed air is bled by means of an
orifice plate. This separate regeneration air flow
is fed through the depressurised vessel. The
humidity stored in the drying agent is taken up by
the air flow and expelled into atmosphere via the
muffler.
Here, regeneration is shown in the
right vessel.
Pressure build-up phase
After dehumidification the pressure in the
regenerated hollow section vessel is built up to
operating pressure, so that the switchover from
regeneration to adsorption can take place at
operating pressure level.
Pressure build-up
Standby phase (only with the dewpoint-sensing control option)
When in standby phase, the fully regenerated vessel is ready for absorption
operation. The system is switched to this vessel, as soon as the measured
dewpoint at the compressed air outlet has reached the set dewpoint value for
switchover.
Switchover When the drying agent in the adsorbing vessel has taken up a sufficient level of
humidity, then the switchover between the vessels will be effected between the
vessels. Following switchover, the above-described process is repeated, with the
adsorption and regeneration now taking place in the respective different vessel.
