OVERVIEW
Limpido EZ Duo
is an automatic swimming pool water treatment system. It is based on two
principles : sterilisation by electrolysis of the salty water and regulation of the pH. Both of these
principles combine to maintaining a pool’s water healthy and limpid.
ELECTROLYSIS OF SALT
Electrolysis separates the salt (NaCl) of salty water into sodium (Na) and Chlorine (Cl). Chlorine
dissolves immediately in the water producing hydrochlorous acid (HClO). This powerful disinfectant
destroys bacteria and algae before it retransforms into salt.
The amount of chlorine needed to disinfect a pool increases with the temperature and the pH
(alkalinity) of the water.
The production of chlorine must be adjusted acccording to the environment and the water’s
characteristics :
♦
the water’s conductivity
♦
the water’s temperature
♦
the volume of the basin to be treated
♦
the water’s pH
For the installation’s safety, the electrolyser produces chlorine only when the flow detector signals the
circulation of water in the cell.
Thus, the electrolyser produces chlorine only during the filtration ranges determined by the swimming
pool’s electrical box’s programming clock. Inside these filtration ranges, the production time is made
up of cycles of two periods (Normal and Reverse) which alternate the polarity of the electrodes. This
reversal of polarity prevents the scaling of the electrodes.
Thus, a production cycle is broken down into 4 phases :
Phase 1, normal production.
Phase 2, rest.
Phase 3, production in reverse mode.
Phase 4, rest.
When a filtration range terminates,
Limpido EZ Duo
stops producing and when the filtration restarts,
it resumes its cycle exactly at the point where it was interrupted.
