Zodiac Ei18 / Ei25 Chlorinator - RetroChlor RC-EI25 25 g/h - Generic

RetroChlor RC-EI25 - 25 g/h Universal Retrofit Chlorinator

The RetroChlor RC-EI25 is a universal plug and play retrofit chlorinator designed as a direct replacement for Zodiac Ei18 and Ei25 systems. It allows you to replace faulty or outdated salt water chlorinators in as little as 15 minutes, avoiding expensive service call-outs and full system replacements.

Australian conditions can accelerate wear on pool equipment through heat, corrosion, vermin damage and power surges. RetroChlor provides a cost-effective solution by renewing your chlorination system without replacing existing plumbing or cell housings.

Exclusive to Best Pool Supplies, this retrofit kit is designed to slot directly into compatible existing installations, restoring reliable chlorine production with minimal effort.

FEATURES

Self-Cleaning Cell

Calcium build-up on cell plates is a common cause of chlorinator failure. RetroChlor uses reverse polarity technology to periodically change current direction, dissolving calcium deposits and extending cell life.

Energy Efficient Operation

Uses modern Switch Mode technology instead of traditional transformers, reducing electrical resistance, lowering energy consumption and minimizing heat generation. This can reduce running costs by up to 50 percent.

Built for Harsh Conditions

Designed with high-grade internal components and acrylic weather shielding to withstand extreme heat and outdoor exposure. Integrated over-current and temperature protection ensures reliable operation in demanding Australian climates.

Simple Retrofit Installation

Engineered to replace existing systems without plumbing changes. The kit connects directly to the existing Zodiac Ei series cell housing for a fast and straightforward upgrade.
