3 Functional principle of the vacuum regulator
3.1 Chlorine Gas
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 chlo-
rine 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.
3.2 Vacuum regulator
The full-vacuum chlorinator used as pressure reducing valve is of central importance for the safety in vacuum
installations. For this reason the C 2214 version has been designed in accordance with the latest findings.
The device combines several functions in one housing:
