Positive pressure chlorine changeover unit
Continuous gas supply
Chlorine gas dosing systems in a water treatment system must be permanently ready for operation so that the water can be sufficiently disinfected at any point. This explains the fitting of the systems with two supply batteries - one side in operation, the other on stand-by. The pressure chlorine changeover valve effects automatic switching between the two cylinders or drum batteries.

Positive pressure chlorine changeover unit C 7524
Intuitive and automated
When the supply from the operating battery runs out, the pressure in the piping system sinks. The control recognises the chlorine shortage using the contact pressure gauge and activates the 3-way motor ball valve for the battery change. The control monitors all operating modes and displays them in a self-explanatory fashion in a flow chart. Relay outputs are also available for the significant operating signals: Empty notification left and right, operating signals left and right and fault message. Manual changeover can be carried out by the push of a button. The motor ball valve is fitted with hand-operated emergency actuation to enable changeover even following a power outage. The residue discharge function can be activated on the control. This function resets at periodic intervals to the battery registered as empty following the changeover. In this way, any remaining residue is used from the chlorine cylinder, but the cylinder cannot permanently cover the chlorine requirements alone.
