The Sal-Chlor Plant incorporates a number of sophisticated protection
systems to protect the electrolytic cell and the rectifier against
operator error, incorrect salt concentrations or system malfunction:
Water Flow Sensor cut off - Unit switches off if no water
flow is detected. The paddle sensor is immersed in the water flow
and utilises water pressure as the switching mechanism. The sensor
employs the latest material technology to ensure protection against
corrosion. Other systems available in the market rely on electrolytic
sensors which sense the presence of water, rather than water flow.
Such electrolytic sensors can enable hydrogen gas to build up to
dangerous levels.
Electrical Interlocking with Filter Pump - The system will
only operate when the filter pump operates, ensuring water flow
to the plant.
Hydrogen Escape - The systems are engineered to prevent
the build up of dangerous levels of hydrogen gas - a by-product
of the electrolytic process.
Ammeter Over-current trip (optional) - The unit will switch
off in the event of current settings being exceeded. Over-current
detection is achieved by 2 separate systems. The first by electronic
detection utilising pre-determined current settings on the ammeter,
and the second through fuse protection.
Alarm - A visual alarm will activate in the event of system
shut down. The option to connect a remote alarm situated outside
of the plant room is available.
Thermal Cut-Off - Installation of electronic microtherrns
will detect overheating and switch off the unit. A visual alarm
will activate.
C Board - The unit's control logic device enables constant
current or constant voltage regulation to the electrolytic cell.
Once the current and voltage levels are set, the rectifier's output
will not exceed these figures, notwithstanding a change in load
conditions at the cell. For example, the addition of salt or other
electrolytes or seasonal temperature variations will increase water
conductivity (lowering resistance) and therefore draw greater current
at the cell. Normally such circumstances would potentially result
in excessive current to the cell beyond its rated design, thus significantly
reducing cell life. The Sal-Chlor circuitry is basically an idiot
proof, self diagnosing system. Power output automatically reduces
or increases to match the pre-set levels.
