Aqualix IC40 Salt Cell Replacement for Pentair IntelliChlor — Titanium Electrodes, 40,000‑Gal

The Aqualix IC40 Salt Cell is a direct-fit replacement cell for Pentair IntelliChlor systems that generates chlorine from salt for gentler, low-maintenance pool sanitation.

If you own a Pentair IntelliChlor IC40 system or a compatible EC-520555 power center and need a reliable replacement cell, this Aqualix unit restores automatic chlorination without the hassle of tablets or liquid chlorine. It uses titanium electrodes with a ruthenium coating for improved durability and a refined flow sensor to reduce false alarms, making it a practical swap for pools up to 40,000 gallons.

How will this salt cell affect the feel and maintenance of my pool water?

By converting dissolved salt into free chlorine, the cell maintains consistent sanitizer levels and reduces the strong odors and harshness sometimes linked with traditional chlorine. Swimmers typically notice softer-feeling water that’s kinder to skin, eyes, and swimwear while you spend less time dosing chemicals manually.

• Produces steady chlorine output for balanced sanitation
• Softer water that minimizes irritation and fabric fading
• Eliminates frequent handling of chlorine tablets or liquid

Is the Aqualix cell durable and compatible with my existing control system?

The cell is built with titanium blades coated in ruthenium to resist corrosion, and its housing is engineered to withstand UV exposure and pool-side heat. It is specifically designed to fit Pentair IntelliChlor IC40 installations and works with the EC-520555 power center for direct push-button control and clear LED status indicators.

• Titanium electrodes with ruthenium plating for longer life
• Improved flow sensor to decrease false 'low salt' or 'no flow' alerts
• Compatible with IC40/EC-520555 power centers for easy control

How easy is installation and ongoing upkeep?

Installation is straightforward: the cell uses standard 2" union connections and includes the power cord, so it integrates with most existing plumbing without special adapters. Routine maintenance follows familiar salt-cell cleaning steps, and the LED indicators simplify monitoring salt level, output and flow so you can spot issues quickly.

• 2" union connections for tool-free plumbing attachment
• Included cord for quick electrical hookup to the power center
• Clear LEDs and display for salt level, output and flow status

What pool size and performance can I expect from this replacement cell?

The Aqualix IC40 replacement is rated for pools up to approximately 40,000 gallons when paired with the appropriate IntelliChlor power center, providing consistent chlorine production for medium and larger residential pools. Its design balances robust output with energy efficiency and reduced alarm nuisance.

• Rated to serve pools up to 40,000 gallons
• Stable chlorine generation with fewer false alarms
• Optimized for residential saltwater systems driven by IC40 electronics

Who is this for: The Aqualix IC40 Salt Cell suits pool owners who already use—or plan to use—a Pentair IntelliChlor IC40/EC-520555 setup and want an affordable, durable replacement cell that restores automatic salt chlorination. It’s ideal for households seeking gentler water, lower chemical handling, and straightforward installation without modifying existing plumbing or the control center.
