  • Pool chlorinators
    Patent number: 5034110
    Abstract: A self cleaning electrolytic chlorinator for swimming pools and water treatment plants comprises a low voltage D.C. power supply unit which cyclically reverses the polarity at the electrodes to shed accumulated deposits which plate out on the electrode surfaces. Damage to the delicate catalytic coating on the electrodes is prevented by stepping the applied potential from a maximum to a minimum value before changing polarity and then stepping the applied potential back to a maximum value.
