Degassing
The entire degassing process is hydraulically synchronised by the "CD" 3-ways motor ball valve 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. The system idles between the intervals.
This programme is recommended for continuous operation.
Make-up degassing:
Make-up degassing automatically activated for every water make-up during continuous or interval
degassing. The process is the same as in continuous degassing. The degassing time is limited by the make-
up time.
