Conditions of use of an chlorination cells
The principle of saltwater chlorination consists in a chemical reaction caused by the presence of electrons on a catalyser (ruthenium), which transforms the salt into active chlorine. This electrochemical reaction naturally consumes the ruthenium. The ruthenium coating on the titanium plates is therefore a consumable. This is why the chlorinator cell is a consumable that, in principle, has a limited life span. Nevertheless, the conditions under which the cell is used have a significant impact on the said life span.
THE FACTORS TO BE TAKEN INTO ACCOUNT TO OPTIMISE THE LIFE OF YOUR AIRFRAME:
Salt rate
At a constant current intensity (without activating the Low Salt function), salt rates below 3 g/l will cause a significant drop in electrode life span (e.g.: -25% at 1 g/l). Devices without a salt rate sensor present a risk for this point if the client does not pay attention to their salt rate. Regular top-ups with unsalted freshwater will lower the salt rate in the swimming pool.

Polarity inversion
Adjusting the device to a polarity inversion of 2 hours (the standard being 4 hours) will reduce electrode life span by almost 30%

Plate production and surface area
The choice of cell (number and surface area of the plates) and the production level, determined by the intensity of the current sent to the cell, have a major impact on the life span of the latter. The higher the number of plates and their surface area, the longer the cell life span will be. We can offer cells with low current densities and thus guarantee high life spans. These cells are more expensive, in line with the size of the electrodes they use.

Cold water operation
It is not rare to see clients leaving the chlorinator running in winter in order to skip overwintering. At a water temperature below 15°C, the electrodes deteriorate rapidly. We highly recommend not doing this.

Influence of global warming
Seasons are starting earlier, ending later, and chlorinators are working a lot more because warm water requires greater disinfection. It is therefore normal for the cells to last for a lower number of seasons than they did 10 years ago.

Operation with scale
A cell that operates with scaled plates will see its life span reduced. Consequently, regular cell maintenance (scale removal with acid) in pools that have a high level of water hardness is extremely important.

Other factors
We are detecting an increased presence of contaminants in swimming pool water (water from private artesian wells is often high in metals or minerals). Some contaminants, particularly metal ones, inhibit and destroy the ruthenium.
This phenomenon can only be detected through a laboratory-performed water analysis.
