1.5. Intended use
The DRYPOINT® M intelligence drying system with integrated nanolter and pressure dew point control is designed for the
removal of aerosols and particles from compressed air and subsequent downstream drying of the air, based on customer
settings.
Operate the DRYPOINT® M intelligence only for the intended purpose and within the limit range specied in the technical
data. Do not operate the unit with any media (uids, gas/vapor mixtures) other than those listed above. Any other use of the
device is deemed improper and poses a risk to persons, property and the environment.
• The unit must be operated within the permissible operating parameter limits (see technical data).
• For proper operation, the air/gas to be treated must be at operating pressure.
• The unit is not suitable for operation in potentially explosive or aggressive atmospheres.
• Do not operate the unit to treat corrosive gases.
• Strictly observe the prescribed storage and transport conditions.
• The unit is not designed for use in conjunction with CO²systems.
With an application in systems with increased requirements for compressed air quality (food or foodstu industry, medical
technology, laboratory equipment or facilities, specialised processes etc.) the operator must decide on measures for the
monitoring of the compressed-air quality. Such equipment might also help enhance the safety of the downstream processes,
preventing damage to persons and property. It is the task of the operator to ensure that the above conditions are met
during the entire operating time.
1.6. Warranty and liability
All liability claims shall be voided, if theDRYPOINT®M intelligence is used improperly, for a purpose other than the intended
or is operated outside the limits specified in the technical data. Improper operation includes especially:
• Incorrect installation, commissioning or operation; insucient maintenance
• Operation with defective components
• Non-compliance with the instructions in this document, in particular the safety instructions
• Execution of construction related interactions or modications of the device
• Non-compliance with the prescribed maintenance intervals
• Use of third-party spare parts that have not been approved by the manufacturer

2.3. Product overview and description
The DRYPOINT® M intelligence 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) responds to changes in the operating pressure,
the pressure dew point at the inlet and uctuations in the compressed air demand. The display and control elements of the
unit are integrated into the control panel (1). The control panel shows the current operating mode as well as the set degree
of drying. A change of the operating mode or the degree of drying is possible at any time during continuous operation.

5
Humid compressed air (2) enters the unit through the
housing head (1) and ows downwards through the core tube
of the membrane element (5). A nanolter is located at the
outlet of the core pipe
(6) xated, which removes residual aerosols and particles
from the compressed air. The resulting condensate is drained
o at the base and is discharged by the oat drain (7).
At the nanolter element, the compressed air is directed in
the opposite direction and the humid compressed air ows
through the membranes of the internal membrane element.
A partial ow (9) of the compressed air
will be branched after the membrane element and bypasses
the sensor continuously in the purge air control. Based on the
sensor signals, the purge air control opens the purge air inlet
to the membrane dryer, if purging is required. As a result, the
purge air pressure drops to the atmospheric pressure and
is much dryer than the compressed air, as the moisture is
distributed to a much larger volume.
The very dry purge air (10) will be routed through the purge
air channel in the head and purge air nozzle (3) to the outside
of the membranes (11) and will be evenly distributed due to
the orderly position of the membranes. This means that there
are two air ows through the membrane element (5) with
dierent humidity content in the counter ow.
Humid compressed air at the inside and dry purge air at the
outside.
Due to the humidity gradient, water diuses from the
compressed air to the purge air. The humid purge air (12) is
then released to the ambient air. The dried compressed air (8)
leaves the membrane dryer.

Installation and operation instructions US-EN
12 DRYPOINT®M intelligence
The control software decides in cycles if and for how long the complete purge air volume is to be supplied in order to
achieve and stabilize the required degree of drying. This process is implemented by means of a cycle-operated solenoid
valve. The time for the two subprocesses described below therefore varies in each cycle, in order to keep the degree of
drying within the specied tolerance range.
Function: Measuring gas ow
A very small partial ow of the dried compressed air
(measuring gas) ows continuously through the internal
channel along the temperature and humidity sensor (S) to the
measuring gas nozzle (1). This sensor continuously measures
the moisture content of the compressed air in the measuring
gas and sends the result to the control.
Function: Purge air ows
The control continuously compares the measured degree of
drying of the measuring gas with the setpoint value for the
DRYPOINT®M intelligence. Tthe valve unit is actuated in
case of deviations: The solenoid core (2) and the 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 without delay.
2.3.2. Operating mode
Constant mode (-14 °F; factory-set) - the pressure dew point at the outlet is kept constant:
In this operating mode, the DRYPOINT®M intelligence keeps the set outlet pressure dew point constant between +50 and
-15 °F. If the set pressure dew point is less than 10 °F below the compressed air temperature, the setpoint pressure dew
point is automatically reduced by one step (to max. -15 °F). As soon as the dierence is again 10 °F, the system returns to
normal operation.
Dynamic mode - the dierence between the compressed air temperature and the outlet pressure dew point is kept
constant:
In this operating mode, the pressure dew point is reduced relative to the compressed air temperature by a specied
dierence between 20 and 100 °F. If the compressed air temperature changes, the pressure dew point follows automatically.
For technical reasons, the compressed air temperature increase is limited to 4 °F/h in order to eliminate insignicant short-
term changes in the ambient conditions on site.

The >>Test<< and >>Value<< push buttons are designed so that inadvertent actuation is impossible. The software only
responds if a button is pressed and held for a certain period of time (approx. 0.2 second).
If one control function is initiated through permanent pressing of the button(s), then the device displays the possible
start of the operation: All green value LEDs (3) are ashing. After releasing the button(s), a time window of 10 seconds is
available for actions. Each actuation of the buttons in this time window extends the time window again to its full length.
After the action has been completed and after no button has been pressed for 10 seconds, the acknowledgment of the
completion of the action by the control M is performed. All green value LEDs (3) are ashing.
Afterwards, the system transfers to normal operation and continues to control based on the specied settings.

Product selection
Example selection drying result for:
• Volume ow usage air: 6.4 cfm
• Operating pressure: 60 psi
• PDP lowering: +40 °F to -15 °F
Search in the table of the service data 4 bar
Column DTP inlet "+40 °F" up to the line "-15 °F" (DTP outlet)
Search a value in this line, which is larger than the usage air volume ow
MColumn MDi 45 meets this requirements with a nominal value of 7.4 cfm
Purge air consumption MDi 45: 2.6 cfm must be deducted from the in lead volume ow
Max. usage air volume ow: 4.8 cfm MDevice is too small, larger device MDi 55 must be selected

3. Installation
3.1. Preconditions
To achieve good drying results, you must ensure ecient preliminary ltration of the compressed air. Without a preliminary
ltration system that meets the recommendations below, it is not possible to achieve satisfactory drying results. For details,
see overview below.
