PoolControls GEMINI 20 Controlled Salt Water Management System for Domestic Pools & Spas

Designed for domestic swimming pools and spas, the GEMINI 20 is a fully controlled salt water management system that continuously analyses pool water chemistry while the system is running. The Gemini Control Unit monitors sanitiser and pH levels, turning on the Salt Unit when more chlorine is required and adjusting pH to help maintain the desired water chemistry.

A multi-electrode probe analyses the water and determines how much chlorine needs to be produced by the electrolytic cell. The system also monitors pH and feeds controlled doses of acid into the pool through a peristaltic pump. Gemini is compatible with conventional and mineral salt pools and spas.

The control unit includes a 24-hour quartz-crystal timer backed by a Real-Time Clock, allowing the system to keep time and maintain AutoMode functions during a power failure. The Gemini System is manufactured from weather-resistant materials and is designed for operation in full sun and rain.

An injection manifold is installed on the return side of the pump and filter, after accessories such as a heater and before the chlorinator cell. This positioning supports the system's water treatment and dosing arrangement.

Features
