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 from the utiliser.
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 the device, 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.

• 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.
If utilised in plants and systems with increased requirements for compressed air quality (such as e.g. food industry, medical
technology, laboratory equipment, special processes, etc.), then the device owner and/or operator must decide about
measures for the monitoring the compressed air quality. 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. Legal and material defect liabilities

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. An
adjustment to the operating mode or degree of drying is possible at all times with ongoing operation.

Damp compressed air (2) enters the unit through the housing
head (1) and ows downwards through the core pipe of the
membrane element (5). A nanolter (6) is tted in the core
pipe outlet
which then frees the compressed air of residual aerosols and
particles. 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) will be routed via the purge air jets
(3)
to the external side of the membranes (11) and then evenly
distributed via the arranged position of the membranes.
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.
Installation and operating manual EN
12 DRYPOINT® M eco control
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.
2.3.2. 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 below the compressed air temperature, then the set point pressure dew
point is reduced by one step (max. -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 Kelvin. 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.
