Accu-Tab PowerBase 3140AT Calcium Hypochlorite Chlorination System

The Accu-Tab® PowerBase® 3140AT Chlorination System is engineered for large-scale commercial pool operations that demand precision, safety, and efficiency. Built on decades of industry expertise and thousands of successful installations, this system pairs patented erosion feeder technology with Accu-Tab Blue SI 3⅛-inch calcium hypochlorite tablets to provide consistent, predictable chlorine delivery for even the most demanding aquatic environments.

With the ability to treat indoor pools up to 2,000,000 gallons, outdoor stabilized pools up to 700,000 gallons, and outdoor unstabilized pools up to 400,000 gallons, the 3140AT is ideal for large municipal facilities, waterparks, and high-bather-load environments. Its robust design includes very few moving parts, an integrated inlet strainer, and large 140-lb tablet capacity, reducing the need for frequent service—often only requiring cleaning once a year.
