Wall holder
A PVC wall holder is used to receive the chlorinator while cylinder is exchanged and closes the pressure
connection at the same time. Thus the entry of humid air is avoided effectively also during replacement of the
cylinder.
Safety blowdown valve
If the inlet valve of the vacuum chlorinator does not close completely due to impurities, it is possible that an
excessive pressure develops in the vacuum piping system which causes undesired chlorination.
To avoid this, the safety blowdown valve is used. It opens at the lowest excessive pressure and discharges the
piping system. The end of the blowdown pipe is run near the gas sensor. Thus an immediate alarm signaling is
ensured.
Activated-carbon cartridge
In almost any installation incl. vacuum systems, temporary shock pressures may occur, which cause the
extremely sensitive safety blowdown valve to respond briefly so that gas warning device is activated. In order
to make sure that only a "real" dangerous situation is indicated by the gas warning device, an activated-carbon
cartridge is integrated in the blowdown pipe, thus avoiding faulty alarms. Only if larger amounts of chlorine
escape will an alarm be reported.
