Pentair Intellichem™ Commercial Water Chemistry Controller 522578 – Dual Pump System

The Pentair Intellichem Commercial Controller 522578 delivers professional-grade automatic water chemistry control for commercial pools and spas. This turnkey system monitors water pH and oxidation‑reduction potential (ORP) and adjusts chemical dosing with precision using dual peristaltic pumps—ideal for managing both sanitizer and acid dosing in tandem.

Engineered for reliability and ease-of-use, the unit features PID-driven chemical feed, programmable dose cycles, and a built-in Langelier Saturation Index calculator. With the integrated ScreenLogic interface, remotely monitor and adjust water chemistry via PC or mobile devices. The system supports both IntelliChlor salt systems and CO₂ auxiliary feeds, ensuring flexible integration into existing infrastructure.

Everything you need is pre-mounted on a 2′ × 2′ backboard: controller, flow cell, sensors, WiFi transceiver, and two Stenner commercial-grade pumps. The dual-pump configuration maintains a continuous sanitizer feed and activates secondary dosing only when required—maximizing chemical efficiency and maintaining steady chlorine levels.

Built for durability, the Intellichem system includes safety interlocks to prevent feed without flow, password protection, and preventative over-feed inhibit logic. A sealed controller and sturdy pump housing ensure reliable performance in harsh aquatic environments. Ideal for hotels, community centers, aquatic facilities, and commercial spas that demand consistent water quality and low maintenance.
