Waterco Hydrochlor ST 2500 25 g/hr Chlorinator for Magnesium Water with Inline Battery Backup Controller

The Waterco Hydrochlor ST 2500 Mineral Chlorinator is designed to provide efficient pool sanitisation for residential swimming pools up to 80,000 litres in temperate climates. Producing up to 25 grams of chlorine per hour, the system converts dissolved pool salt or Waterco Mineral Crystals into sanitising chlorine, helping maintain clear, healthy and comfortable swimming conditions throughout the year.

At the centre of the system is Waterco's intelligent energy-saving power pack, which utilises switch mode power technology to improve electrical efficiency while maintaining dependable chlorine output. The intelligent controller automatically recognises the connected chlorinator cell and adjusts operating parameters to suit, helping optimise performance and reduce energy consumption.

The Hydrochlor ST 2500 is suitable for both mineral and salt chlorination applications, offering flexibility for different pool water management preferences. An integrated timer allows straightforward scheduling of filtration and chlorination cycles, while LED status indicators provide clear visibility of system operation, output levels and protection functions.

The self-cleaning chlorinator cell incorporates automatic polarity reversal technology to reduce calcium build-up on the cell plates and minimise maintenance requirements. Additional protective features include salt level monitoring, no-flow detection and automatic output limitation when salinity exceeds recommended operating levels. Combined with durable construction and 50mm plumbing connections, the Hydrochlor ST 2500 is engineered for dependable long-term pool sanitisation.
