Servitec

Theoretical Principles

1) Vacuum generation

The pumps cuts in, the water level drops and a vacuum is generated in the vacuum spray tube. The circuit water (optionally make-up water) is atomised in the generated vacuum releasing the dissolved gases due to the vacuum and the large contact surface.

2) Degassing start

The pump shuts down. Water is sprayed until the vacuum spray tube is completely filled.

3) Degassing

All released gases are reliably precipitated via the automatic fan.

4) Idling time

System pressure has built up in the spray tube. The system water within the tube is nearly gas-free and will be returned to the network in the following cycle.
