Reflex Servitec S Original Operating Manual

Description of the device
Vacuum spray degassing — 20.05.2019 English — 9
Degassing
The entire degassing process is hydraulically regulated using the integrated pressure sensor and the device controller. The system
monitors the operating states and displays them at the controller. 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.
Make
-up degassing:
Make
-up degassing is automatically activated for every water make-up during continuous or interval
degassing in Magcontrol and Levelcontrol operating modes. Activation takes electrically by application of
an external make
-up request from the pressure maintenance station
The make
-up motorized ball valve is opened and the system motorized ball valve is closed.
Make-up variants
There are two make-up variants. Both are monitored via the make-up time and the make-up cycles.

Note!
For pipe lengths greater t
han 8 m we recommend selecting the next largest nominal diameter DN 20. Max. pipe
length 25 m.
1 “WC” make-up line nominal diameter DN 15 6 “DC” degassing line (degassed water to the facility
system), nominal diameter DN 15; DN 20 (8 m-25 m)
2 Optional add-on device (see Chapter Optional
equipment and accessories)
7 “DC” degassing line (gas-rich water from the facility
system), nominal diameter DN 15; DN 20 (8 m-25 m)

maintenance station
Magcontrol:
For systems with
bladder expansion vessels.
– 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.
Levelcontrol:
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.
