Avoiding inadvertent chlorine gas dosing
Chlorinators working in accordance with DIN 19606 operate under a vacuum generated by an injector. The motive water required is provided either by a motive water pump or from a pressurised water pipe. The vacuum breaker is used when the system causes a negative pressure at the ejector of more than 0.1 bar, even when the motive water supply is switched off. This negative pressure can be caused by a geodesic height difference to the chlorine solution introduction or a negative pressure in the main line.
The vacuum breaker is setup in the same manner as an injector non-return valve. The opening negative pressure amounts to only 0.05 bar (compared to 0.1 bar with an injector non-return valve). This causes the vacuum breaker to let air enter the pipe line before chlorine is sucked in unintentionally.
