Product Overview

The IntelliChlor LT25 cell (EC-523747) is a high-efficiency salt-chlorine generator designed for pools up to 25,000 gallons. With a chlorine production rate of approximately 0.90 lbs per 24 hours at 100% output, it converts dissolved salt into sanitizing chlorine to eliminate the need for manual chlorine addition. It’s engineered to drop‐in replace legacy cells with the same plumbing length, and offers advanced diagnostics, modular serviceability, and simplified maintenance compared to prior generation models.

Ideal For

• Pool owners with inground pools up to ~25,000 gallons seeking an efficient, low-maintenance salt-chlorination solution.

• Systems upgrading from older INTELLICHLOR or iChlor salt cells who want a modern replacement without re-plumbing.

• Installations where automation integration, remote diagnostics, and easy maintenance are priorities.

• Service professionals recommending long-life salt cell upgrades to reduce labor and chemical costs.

Key Features

• 25K Gallon Capacity – sized to serve pools up to approximately 25,000 gallons. 

• 0.90 lbs/Day Chlorine Production (at 100% output) – robust output to maintain sanitization. 

• Drop-In Replacement – fits legacy Pentair salt systems without changing plumbing length; simplifies retrofit installations. 

• Modular Design & Diagnostics – easier sensor/electronics replacement, built-in diagnostics and LCD/LED interface for monitoring. 

• Optimized Salt and Flow Sensing – advanced conductivity sensor and SmartSense™ technology to adjust output and maximize cell life.
  Acid-Cleaning Kit Included – helps simplify annual maintenance and extend the service life of the cell. 

Customer-Facing Q&A

Q: Does this cell require a new power center or wiring?
A: No. The LT25 cell is designed to work with existing Pentair IntelliChlor Power Center units and uses the same plumbing length, making it a straightforward retrofit.

Q: What kind of pool size is this cell rated for?
A: This model is sized for pools up to approximately 25,000 gallons. For larger pools, consider higher-capacity models.

Q: How do I maintain the salt cell?
A: Maintain salt levels (typically around 3,000–4,500 ppm), ensure adequate flow, and use the included acid-cleaning kit as recommended when diagnostic alerts appear.

Q: Do I still need to handle tablets or liquid chlorine?
A: Generally no. The salt cell generates chlorine automatically from the dissolved salt, so manual addition of chlorine is greatly reduced or eliminated.

Q: How long will this cell last?
A: Service life depends on water chemistry, flow, and maintenance. With proper care, these cells typically provide years of operation before replacement is needed.
