1.5. Intended use
The DRYPOINT® M eco control drying system with integrated nanolter and pressure dew point control is designed for the
removal of aerosols and particles from compressed air and subsequent targeted drying of the air according to the individual
settings by the user.
Operate the DRYPOINT® M eco control only for the intended purpose and within the limit range specied in the technical
data. Do not operate the unit with any media (uids, gas/vapour mixtures) other than those listed above. Any other use
of this system, which exceeds the intended use, is hereby deemed to be improper and can cause a hazard for the safety of
people and the environment.
• Operating the unit may only be executed within the permissible operating parameter limits (refer to technical data).
• Operating pressure will be required for the proper functional operation.
• The device is not suitable for operation in explosion hazard areas as well as in areas with aggressive atmospheres.
• Do not operate the device with corrosive gases.
• Strictly observe the prescribed storage and transport conditions.
• The device is not suitable for use in conjunction with CO² systems.
The operating company must establish measures for the monitoring of the compressed air quality when using industrial
processes with higher quality requirements (e.g. food industry, medical technology, laboratory equipment, special processes,
etc.). These inuence the safety for subsequent processes and can prevent injuries to people and damage to plants and
systems. It is the duty of the owner and/or operator to always comply with the stated conditions during the entire operating
time.
1.6. Warranty and liability for defects
All liability claims will be deemed to be invalid when the DRYPOINT-M® eco control is not utilised in accordance with its
intended use or is operated outside the specifications stated in the technical data, this particularly includes:
• Technically incorrect installation, incorrect commissioning, incorrect maintenance or incorrect operation
• Operation with defective components
• Non-compliance with the instructions in this manual, in particular the safety instructions
• Execution of constructive interventions or modications on the device
• Non-compliance with the prescribed maintenance intervals
• Use of third-party spare parts that have not been approved by the manufacturer for repair and maintenance works

2.3. Product overview and description
The DRYPOINT® M eco control is a drying system that guarantees a constant degree of drying even under uctuating
operating conditions. The sensor system integrated into the control unit (2) reacts to uctuating operating pressure, inlet
pressure dew point as well as dierential requirements for compressed air quantities. The display and control elements are
integrated into the control panel (1). The operating modes as well as specied degree of drying are displayed here. A change
of the operating mode or the degree of drying is always possible during running operation.

Moist compressed air (2) enters the unit through the housing
head (1) and ows downwards through the core pipe of the
membrane element (5) into the housing (4). It then passes
through the nanolter (6) installed at the bottom outlet of
the core tube where all residual aerosols and particles are
removed from the compressed air. Separated condensate
ows out of the base and is routed through the oat drain-o
conduit (7).
The ow direction is reversed in the nanolter element area
and the damp compressed air ows through the membranes
of the internal membrane element.
A part of the compressed air ow
(9) is diverted downstream of the membrane element and
passed by the sensor continuously in the purge air control.
The sensor measuring results will be evaluated in the purge
air control and the purge air feed to the membrane dryer will
be opened as required. As a result, the purge air decreases to
atmospheric pressure and is considerably dryer as the damp
contained in the compressed air is distributed to a multiple of
the original volume.
The very dry purge air (10) is fed via the purge air duct in
the head and the purge air nozzle (3) on the external side of
the diaphragm (11) and evenly distributed by the arranged
position of the diaphragms. This means that two air ows
move through the membrane element in an opposite
direction with dierential damp content(5):
Damp compressed air on the inside and dry purge air on the
outside.
Due to the damp dierence, water diuses from the
compressed air into the purge air. The damp purge air (12) is
then released to the ambient air. The compressed air (8) exits
as dry from the membrane dryer.
EN Installation and operation manual
DRYPOINT® M eco control 13
The control software decides in dened cycles on the basis of the measurement results whether, and for how long, the
complete purge air volume must be supplied in order to achieve and stabilise the required degree of drying. This process
will be implemented via a targeted cycling of a solenoid valve. The duration for both subsequent described process steps
therefore varies in every cycle to retain the degree of drying within the specied tolerance range.
Function: Measuring gas ows
A very small partial ow of the dried compressed air
(measuring gas) ows continuously through the internal
duct guide past a temperature and damp sensor (S) to the
measuring gas jet (1). This sensor continuously species the
degree of drying for the compressed air in the measuring gas
and noties the result to the control system.
Function: Purge air ows
The control system continuously compares the measured
degree of drying of the measuring gas with the individual
specied set point value on the DRYPOINT® M eco control.
The valve unit will be actuated with deviations: The solenoid
core (2) and piston (3) close the valve seat so that the
compressed air ows through the purge air nozzle (4)
to the membrane dryer. The drying process commences
immediately.
2.4.2. Operating mode
Constant mode (-10 °C; factory-set as default) - Setting for a constant outlet pressure dew point:
The DRYPOINT® M eco control constantly retains the pressure dew point at the outlet between +10 and –26 °C in this
operating mode. If the set pressure dew point is <5K (kelvin) below the compressed-air temperature, then the set point
pressure dew point is reduced by one step (maximum. -26 °C). As soon as the minimum dierence of 5K is retained, then the
system returns to normal mode.
Dynamic mode - constant dierence between compressed air temperature and outlet pressure dew point:
In this operating mode, the pressure dew point is reduced relative to the compressed air temperature by a specied
dierence between 10 and 55 K. If the compressed air temperature alters, then the pressure dew point will automatically
follow suit. For programme-technical reasons, an increase in the compressed air temperature is limited to 2 °C/h in order to
reduce short-term alterations in the ambient conditions at the installation and/or assembly location.

The pressure points on the >>Test<< and >>Value<< buttons are designed in such a way that inadvertent touching cannot
trigger operating functions. The software is programmed in such a way that a button must be pressed for a longer time
(approx. 0.2 second) to acquire a desired operating function.
If an operation function is initiated with a continuous pressing of the button(s), then the device will indicate the possible
commencement of the operation: All green value LEDs (3) ash. A time span of 10 seconds is then open for the action after
releasing the button(s). Every actuation of a button during this time span will result in the time span being available again
for the complete duration.
Once the action has been completed and no button has been pressed for 10 seconds, then the conrmation for nalising
the action will be executed via the control . All green value LEDs (3) ash.
The system then transfers into normal mode and will be controlled on the basis of the prescribed settings.
