No more mixing, measuring, or handling liquid or tablet chlorine again. Now you can turn ordinary table salt into a self-regenerating supply of pure chlorine for both swimming pool and spa that's clean, clear, and luxuriously soft. Electronic chlorination has become the trouble-free, safe, and affordable alternative to using harsh, chemically-produced chlorine to sanitize swimming pools and spas. The key is Hayward’s patented Turbo Cell, a specially designed converter connected to the control unit. As water passes through the Turbo Cell, an extremely safe electrical charge turns the salt previously added to the water into fresh sanitizing chlorine which is then dispensed evenly throughout the pool. Electronic chlorination is the ideal alternative to traditional factory produced chlorine for soft, silky-smooth water.
