Description
A
Water softener The water softener provides the softened mains water required for the electrolysis.
B
Chiller and/or
heater
An optional chiller or heater can be used to provide the correct mains water temperature.
C
Brine tank
The brine tank is used for preparation and storage of brine.
D
Brine dosing
station
The brine dosing station doses the required amount of brine into the process.
E
Selcoperm
electrolyser
The Selcoperm electrolyser comprises:
• Electrolysis cells
• Hydraulic chamber
• Control cabinet
• 7" multi-colour touchscreen for operating and monitoring the whole electrolysis system.
F
Rectifier
The rectifier converts the alternating current (AC) from the power supply into the direct current (DC) needed to
run the Selcoperm electrolyser.
G
Degassing and
storage tank
with sensors
and degassing
fan
In the degassing and storage tank the hydrogen gas is removed from the sodium hypochlorite solution. The
degassing and storage tank must be installed as close as possible to the Selcoperm electrolyser. The level in the
tank is monitored by a level sensor. The degassing fan ensures a safe dilution and removal of hydrogen gas. The
sodium hypochlorite solution can be dosed directly from the tank to the point of application. It is also possible to
pump the sodium hypochlorite solution from the tank into separate storage tanks.
H
Gas warning
system
The gas warning system monitors the concentration of hydrogen gas at the installation location permanently.
I
Building
ventilation
Natural ventilation via ventilation holes or technical ventilation is required at the installation location. Legal
requirements and local standards must be observed.
K
DC cable set
Insulated flexible copper cable for direct current connection between the Selcoperm electroyser and the rectifier.

Brine line
3
Sodium
hypochlorite
solution line
Besides the sodium hypochlorite solution this line contains hydrogen gas, which is removed in the downstream
degassing and storage tank.
4
Exhaust air line
Through this line the dilution air (99 %) and the hydrogen gas (1 %) are removed from the degassing and storage
tank by means of forced ventilation. The exhaust air line has to be directed with a constant upwards incline to a
safe discharge point outside the building.

Drain
A drain for maintenance is required on site.
