Product Overview

The Pentair IntelliChlor LT25 Salt Chlorine Generator Cell | EC-523747 is a next-generation salt chlorination cell designed for residential pools up to 25,000 gallons. Built as part of Pentair’s IntelliChlor LT platform, this replacement cell converts dissolved salt in pool water into chlorine automatically, helping maintain clean, clear, and comfortable water with less manual chlorine handling.

The IntelliChlor LT25 is designed with improved serviceability, more accurate salt sensing, and a modular platform compared with earlier salt chlorine generator designs. It is commonly used as an upgrade or replacement option for compatible Pentair IntelliChlor systems and is frequently referenced as a replacement for older IC20-style applications when the system configuration is compatible.

This cell requires a compatible Pentair IntelliChlor Power Center or supported Pentair automation/control system to operate.

Benefits

The Pentair EC-523747 IntelliChlor LT25 helps simplify pool care by producing chlorine automatically from salt already dissolved in the pool water. This helps reduce the need for frequent manual chlorine dosing while maintaining consistent sanitation.

The LT25 platform is designed to improve ease of service and salt-level accuracy. Its self-cleaning operation helps reduce scale buildup, supporting more consistent performance when water chemistry is properly maintained.

For pool owners with compatible Pentair systems, this cell provides an efficient way to maintain clear, sanitized water with less daily chemical handling. For pool professionals, the EC-523747 offers a modern replacement option for supported IntelliChlor salt system installations.

Specifications

Compatibility Notes

The Pentair EC-523747 is designed for compatible Pentair IntelliChlor salt chlorination systems.

Common compatibility references include:

• Pentair IntelliChlor LT systems
• Compatible IntelliChlor Power Center installations
• Pentair IntelliTouch automation systems
• Pentair EasyTouch automation systems
• Pentair IntelliCenter automation systems
• Select IntelliChlor IC20 replacement applications where system compatibility is confirmed

Always confirm the existing salt system model, power center compatibility, plumbing layout, cell type, firmware/control compatibility, and pool gallon rating before ordering.

Installation Notes

This salt cell should be installed by a qualified pool professional. Turn off power to the salt system and pool circulation equipment before removing or installing the cell.

Before startup, confirm that the pool is properly sized for a 25,000-gallon salt cell and that salt level, stabilizer, pH, alkalinity, calcium hardness, and overall water balance are within recommended operating ranges.

After installation, verify proper water flow, check for leaks, confirm cell communication, and test chlorine output through the compatible Pentair control system.
