Product Overview

The Pentair IntelliChem 522621 is an advanced water chemistry controller designed to automatically monitor and help manage pool and spa pH and sanitizer levels. This package includes the IntelliChem controller, acid tank, and tank-mounted acid pump, making it ideal for pool owners who want more consistent water balance with less manual chemical adjustment.

IntelliChem can operate independently or integrate with compatible Pentair automation systems, helping maintain proper water chemistry by dispensing the right amount of acid when needed. It is designed for use with muriatic acid and works with IntelliChlor salt chlorine generator systems for complete chemical management.

Ideal For

• Residential pools and spas
• Pools using Pentair IntelliChlor salt chlorine generators
• Pool owners who want automated pH control
• Systems using muriatic acid for pH reduction
• Pentair automation setups using IntelliTouch, EasyTouch, SunTouch, or ScreenLogic-compatible systems

Key Features

• Automatic pH and sanitizer monitoring to help maintain balanced pool water
• Includes acid tank and tank-mounted pump for automatic acid dispensing
• Works independently or with Pentair automation systems
• Built-in Langelier Saturation Index calculator to help determine if water is balanced
• Flow sensor protection helps prevent chemical feed when there is no system flow
• Password-protected access helps prevent accidental setting changes or tampering
• Programmable feed cycles and mix times for precise chemical control
• NSF Certified and ANSI Standard 50 Certified

Benefits

The Pentair IntelliChem 522621 helps reduce the guesswork involved in pool water maintenance. By continuously monitoring chemistry and dispensing acid as needed, it helps keep pH levels more stable, improves swimmer comfort, and supports better sanitizer performance.

For customers with Pentair automation or IntelliChlor systems, IntelliChem adds another layer of convenience by helping automate one of the most time-sensitive parts of pool care: chemical balance.
