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, be-
fore 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.
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 pres-
sure build-up.
With the dewpoint-sensing control option, the regeneration phase is followed by a standby
phase.

EN | User Manual Technical product description
16 K-MT 10-95/D3
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.
Dehumidification 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.
Pressure build-up phase
After dehumidication 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 chamber has taken up a sufcient 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.

EN | User Manual Technical product description
K-MT 10-95/D3 17
Available options
The following options are available for the dryer:
◊ Start-up device
◊ Signalling contacts of the control system
◊ Regeneration gas recirculation
◊ Dewpoint-sensing control
◊ Fine lter mufer
◊ Nozzle kit
Start-up device
A start-up device basically consists of a pressure holding device, which is located at the rear
of the dryer. The pressure holding device ensures that pressure can build up in the dryer and
adsorption take place.
It is always required when an empty compressed air reservoir or an empty compressed air
system must be lled downstream of the dryer (e.g. following weekend shutdowns and when
the pressure in the compressed air system can frequently drop below the stated operating
pressure).
Signalling contacts of the control system
The control system is equipped with a digital input for the synchronised operation with a
compressor. This feature allows for synchronised and thus efcient dryer operation with
discontinuous compressor operation.
Compressor synchronisation helps reduce energy costs, as the dryer can be operated inde-
pendently of the compressor.
The compressor synchronisation controller is a higher-level controller than the pressure dew
point controller (see below). When both options are in place, the compressor synchronisation
controller is treated as the prime controller.
The control system can also be equipped with an optional operation signalling contact with
which the dryer operation can be monitored from an external device. Dryers with the optional
dewpoint-sensing control are equipped with such a contact as standard. It is used for the
transmission of operating signals and for the output of dewpoint alarms.
Regeneration gas recirculation
When the compressor is switched off, the regeneration gas recirculation serves to continue
regeneration provided a sufciently large compressed air volume is present downstream of
the dryer. The regeneration process must be continued and ended so that the drying agent
does not become unusable prematurely.
Regeneration gas recirculation depends on the properties of the installed compressed air
network and should be discussed with the manufacturer beforehand.
Dewpoint-sensing control
With a dewpoint-sensing control system, you can operate the dryer in xed or variable
cycles. In the xed cycle, switchover is effected after a xed time period (usually after 5
minutes). In the variable cycle, the switchover is effected in relation to the dew point reached
and the charging of the drying agent . The adsorption time in the variable cycle amounts to
60 minutes maximum.
Fine filter muffler
A ne lter mufer is used to reduce the noise emission of the dryer to lower levels than the
standard mufer can provide. If installed, the ne lter mufer replaces the original installed
mufer.

EN | User Manual Technical product description
18 K-MT 10-95/D3
Nozzle kit
In the case that the operating pressure deviates from the standard design pressure (7bare)
it is possible that the amount of necessary regeneration air changes. This effect may have
a negative impact on the cost-effectiveness of the dryer. To prevent this, it is possible to
replace the built in regeneration air nozzle by a nozzle with a modied bore. This replacement
optimizes the regeneration air consumption and therefore restores the energy efciency of
the dryer. To receive more information on this conversion, please contact the manufacturer.
