Our cells are self-cleaning by automatic polarity inversion. It is pledge of performance and reliability. It avoids visual controls and manual cleanings with acid. POOL TECHNOLOGIE goes even further: to adapt the frequency of polarity inversion to the hardness of the water, a large number of our models propose an adjustable polarity inversion. The harder the water is, the more the frequency of inversion must be important for avoiding the scaling of the cell.
However, the adjustment must be made carefully: the frequency of inversion reduces the lifespan of the cell. The technology of current monitoring minimizes this major inconvenience because it allows a progressive polarity inversion; not traumatic for the plates coating. The risks of local tearing of the coating are eliminated by the progressive current input in the cells. The current monitoring also allows us to provide devices with a polarity inversion memory.
After a filtration stop, the cycle of polarity inversion starts again by taking into account the time of inversion made before the filtration stop.
