The Pentair IntelliChlor® Plus40 Salt Chlorine Generator Cell provides an efficient and convenient solution for maintaining crystal-clear, sanitized pool water in residential pools up to 40,000 gallons. By converting ordinary table salt into chlorine, it eliminates the need for traditional chlorine products, simplifying pool maintenance.​The Plus40 ensures consistent and adequate chlorination to keep your pool water safe and clean. Its design allows for easy drop-in replacement of existing Pentair salt chlorine generators without requiring additional plumbing, making upgrades straightforward and hassle-free

The IntelliChlor LT25 features user-friendly controls and a robust construction, ensuring durability and ease of operation. By integrating advanced electrolytic chlorine generation technology, it provides a reliable and efficient method for pool sanitation, enhancing the overall swimming experience.

The IntelliChlor Plus40 features a thoughtfully designed modular layout, allowing the onboard computer to be separated from the cell. This design makes it safer to clean the cell without risking damage to the electronics—an improvement over earlier models where the entire unit had to be handled as one piece. In addition to improved serviceability, the modular design enables independent replacement of internal components like sensors and electronics. Combined with SmartSense™ technology, a redesigned conductivity sensor, and a built-in diagnostic display, the Plus40 offers a smarter, more maintainable solution for saltwater pool sanitation.
