Product Overview
The Pentair 522577 IntelliChem Commercial 1-Pump System is a commercial water chemistry automation system designed to monitor and help manage pool and spa chemistry. This system is used to track key water chemistry values such as pH, ORP, calculated sanitizer level, and temperature, then control chemical feed based on system programming.

This 1-pump configuration is commonly used when a commercial pool system requires one automated chemical feed pump, such as for acid feed, sanitizer feed, or another approved chemical feed application depending on the installation design.

Ideal For
Commercial pools, aquatic facilities, hotels, resorts, HOA pools, health clubs, and high-use pool or spa systems that require automated chemical monitoring with a single chemical feed pump.

Benefits
The Pentair 522577 Commercial IntelliChem 1-Pump System helps reduce manual water chemistry adjustments by monitoring pool water and controlling a chemical feed pump automatically. This can help improve water balance consistency, reduce chemical overfeed, support clearer water, and simplify commercial pool maintenance.

The 1-pump configuration is a strong option for facilities that need automated control of one chemical feed function while maintaining the monitoring and control benefits of the IntelliChem platform.

Commercial Installation Note
This is a commercial chemical automation system. Installation should be performed by a qualified pool professional familiar with commercial pool codes, ORP/pH sensors, chemical feed pumps, flow interlocks, injection points, and local health department requirements.
