Replace a worn chlorinator cell without swapping the whole controller using this salt water pool chlorinator system fit for Hayward W3T-Cell-15 (T15), also compatible with AquaRite, AquaRite Pro, SwimPure Plus, AquaPlus, ProLogic, and OmniLogic systems (controller software version must be r1.5 or higher; press the diagnostics button 7 times to check). The cell produces up to 1.52 lb. per day (28.7 g per hour) of chlorine, handling in-ground pools up to 40000 gal. without constant tablet runs. Titanium electrode plates and a sturdy ABS shell resist corrosion from salt, chlorine, and seasonal pool chemistry, extending cell life compared to lower-grade plates that pit and erode after one season. Electrolytic salt-to-chlorine conversion delivers a gentler swim experience with less eye irritation and milder chlorine odor, while balancing pH and hardness for softer feel on skin and hair. Setup takes about 10 minutes: connect the pipes, insert the controller, and run without modifying existing plumbing, then clean the cell every three months using included O-rings and the pipe cleaning tool. The 15 ft. (4.6 m) power cord reaches most in-ground equipment pads, unit dimensions 13.3 in. x 4.3 in. x 5.0 in. (339 mm x 109 mm x 128 mm) at 4.4 lb. (2.0 kg), model 89420001. Ideal for Hayward salt system owners replacing a spent cell, pool techs servicing backyard installations, and homeowners switching from tablet chlorine to a saltwater system.
