General data Principle of vacuum chlorine gas dosing systems Principle of a vacuum chlorine gas dosing system Vacuum regulator Dosing regulator Adsorption cylinder (option) Safety valve (option) Dosing regulator (C) The chlorine gas volume flow is adjusted with the dosing regulator. This can be effected manually or automatically via motor control. VGB models combine a vacuum regulator and a dosing unit in a compact enclosure. They are not available with change-over device or servomotor for dosing regulator. Change-over device (option) Water apparatus (option) Injectors have the task to...

2. Construction and function Vaccuperm VGB-103 Vaccuperm VGB-103 compact unit • Vacuum regulator and dosing regulator in a single unit for direct mounting on a chlorine cylinder. • Up to 2000 g/h can be extracted. The maximum extraction quantity depends on the chlorine cylinder content: It is 1 % per hour of the content by weight. For a short time (max. 10 minutes) it is possible to extract the triple of this. 1 Vaccuperm VGB-103 with USA yoke Vaccuperm 103-100 Chlorine gas adsorption cylinder Injector

Dosing station with vacuum change-over device Combination of several VGA-111 and VGA-113 • Continuous gas dosing without interrupting the process. • Two vacuum regulators for mounting on gas cylinder header lines. • Up to 4 dosing regulators can be installed separately. • If the first cylinder row is empty, the change-over device immediately changes over to the next vacuum regulator at the full chlorine cylinder row. • The safety valve avoids excess pressure in the vacuum lines leaving the cylinder room. Fig. 11 Dosing station with vacuum change-over device (VGA-111 and VGA-113) Pos....
