Instruction Manual

Purpose of full-vacuum chlorinators Chlorine gas is important for the disinfection of potable and swimming pool water but also represents a source of danger as far as handling, transportation
and storage are concerned. Therefore the vacuum principle has been used in chlorination installations
already for decades. According to this principle, the pressure of the chlorine gas is reduced to vacuum,
and only then, if the vacuum is sufficient, will chlorine gas flow to the metering point.

The main safety aspect is that the escape of chlorine gas is actually avoided. Even in the case of a line
rupture chlorine gas cannot escape but only ambient air can be primed.

Full-vacuum chlorinator C 2212
The full-vacuum chlorinator used as pressure reducing valve is of central importance for the safety
in vacuum installations. For this reason the C 2212 version has been designed in accordance with the
highest safety standards. Its compact design is most suitable for installations of simple structure.
The C 2212 combines several functions in one housing:

(all numbers in brackets refer to the schematic diagram on the page MB 2 04 12 / 3).

a) Vacuum regulation
In the initial position the ball (1) rests on the valve seat (2). It is pressed onto the seat by the locking
spring (3) and the chlorine cylinder pressure and closes the system. After switching on the ejector
(water-jet pump), a vacuum is generated. Thevacuum applies a force to the working diaphragm
(7) of the full-vacuum chlorinator, which is directed to the right. This force is transferred to the valve ball
(1) by the valve rod (8) so that chlorine gas enters the vacuum system. If the vacuum breaks down, the
valve ball falls back immediately onto the valve seat and stops the chlorine gas supply.

b) Flow indication and adjustment A flow meter is mounted on the front side of the C 2212 full-vacuum chlorinator. The positon of the float element (11) indicates the flow directly at the scale on the gauge tube. Gauge tubes with maximum rates between 25...4000 g Cl2/h are available.
