4.3 Function
The device is suited for the degassing of water from the plant and make-up water. It removes up to 90 % of the dissolved gases
from the water. The degassing operation uses timer-controlled cycles.
A cycle comprises the following phases:
1. Pump down to create a vacuum
The pump “PU” creates a vacuum in the spray pipe. The “DC” feed (during “WC” make-up degassing) to the vacuum spray
tube “VT” is open. Gas-rich water is sprayed into the spray tube via a nozzle. The system is set up so that the pump draws
more water from the spray tube than can flow through the nozzle.
2. Injection
The "DC“ feed of gas-rich water from the system to the "VT" vacuum spray tube is opened. Depending on the requirement,
partial flows of the gas-rich system water and the make-up water are atomised in the vacuum spray tube via the "DC" and
"WC" lines. The large surface of the atomised water and the gas saturation headway to the vacuum result in a degassing of
the water. The "PU" pump returns degassed water from the vacuum spray tube to the system where it again begins to
dissolve gases. Here it is able to dissolve gases again.
3. Discharge
The "PU" pump shuts off. The system continues to inject and degas water in the "VT" vacuum spray tube. The water level in
the vacuum spray pipe rises. The gases separated from the water are discharged via the "DV" degassing valve.
4. Idling time
When the gas has been discharged, the device will remain idling until the next cycle is started.

Description of the device
Vacuum spray degassing — 28.08.2019 - Rev. B English — 9
Degassing
The entire degassing process is hydraulically regulated using the integrated pressure sensor and the device controller. The
operating conditions are monitored and can be called up and displayed from the device controller via a smartphone loaded with
the Reflex Control Smart app. The controller provides 3 different degassing programmes and 2 different make-up variants for
selection and setting.
Degassing programmes
• Continuous degassing:
For continued degassing over several hours or days in a sequence of degassing cycles without idling periods. This
programme is recommended after commissioning and repairs.
• Interval degassing:
Interval degassing comprises a limited number of degassing cycles. There is an idling time between the intervals. This
programme is recommended for continuous operation.
• Makeup degassing:
In Magcontrol and Levelcontrol mode, make-up degassing is automatically activated upon every make-up request during
continuous or interval degassing. The make-up volume is monitored via the make-up time and the make-up cycles.
Make-up variants
There are two make-up variants for the device. These are selected in the controller and set for the device:
• MagControl (for systems with diaphragm expansion tanks):
Using the integrated "PIS" pressure sensor, the system registers and monitors the pressure in the heating or cooling system.
Make-up degassing is activated as soon as the pressure drops below the calculated filling pressure.
• Level control (for systems with pressure maintenance stations):
The pressure maintenance station uses the "LIS" pressure pick-up to determine the water level in the expansion vessel. The
make-up function is triggered by a 230 V signal.
If none of the above described make-up variants is selected, the following selection should be made via the Reflex Control Smart
app:
• "None":
Automatic make-up is deactivated. A pressure-independent system degassing is taking place. Automatic system pressure
monitoring must be reliably externally provided.

Note!
For pipe lengths greater than 8
m we recommend selecting the next largest nominal diameter DN 20. Max. pipe
length 25 m.

Technical data
Vacuum spray degassing — 28.08.2019 - Rev. B English — 11
• Fillsoft for softening the make-up water from the potable water supply system.
– Fillsoft is installed between Fillset and the device. The device controller evaluates the make-up quantities and signals
the required replacement of the softening cartridges.
• Reflexomat for systems with pressure maintenance stations.
– The combination of Reflexomat and device should be given preference. In spite of a degassed network, the
Reflexomat ensures extremely flexible operation at constant pressure. Make-up is executed depending on the water
level measured with the "LIS" level sensor of the Reflexomat in the expansion vessel of the pressure maintenance
station. If there is a make-up requirement, the Reflexomat activates the Servitec make-up function via a 230V signal.

Operating mode “Magcontrol” is set using the Reflex Control smart app (see chapter 9.1 "Reflex Control Smart" on page 23 ). This
operating mode is used for facility systems with an expansion vessel. Water is added dependent on the pressure in the facility
system and the set minimum operating pressure p0 (see chapter 7.2 "Setting the minimum operating pressure for Magcontrol" on
page 21 ). The pressure sensor required for this is integrated in the device. The degassing lines are connected close to the bladder
expansion vessel. This ensures that the pressure monitoring for water make-up is provided.
6.4.2 Level dependent "Levelcontrol" make-up mode
Operating mode “Levelcontrol” is set using the Reflex Control Smart App see chapter 9.1 "Reflex Control Smart" on page 23 . This
operating mode is used for systems with pressure maintenance stations and enables flexible operation at constant pressure.
Water is added depending on the measured filling level in the expansion vessel of the pressure maintenance station. The "LIS“
pressure transducer determines the filling level and sends this value to the controller of the pressure maintenance station. The
controller sends a 230 V signal to the device controller when the filling level in the expansion vessel has fallen below the set value.
The device controller regulates the motor actuator of the motorized ball valve in the "WC" make-up line. This ensures controlled
make-up with water and monitoring of the make-up time and cycles.
