Automatic selector switch

Gas-feed chlorinators are generally equipped with two chlorine supply units (bottles or barrels). The non-stop operation of the system round the clock is possible only in this way. „Deepvacuum” is needed to actuate the switchover on the forthcoming chlorine tank, which arises due to the switching pressure difference between the full and empty container.

After the switchover the sealing ring closes with maximum safety, that allows the change of the chlorine bottles in operation. The application of this unit is recommended over 200 g/h dosing capacity. It had been designed for devices with 2, 4, and 10 kg/h dosing capacity.
