Waterco Hydrochlor ST Salt Chlorinator

At a Glance

The Waterco Hydrochlor ST is a straightforward salt chlorinator in 2000, 2500 and 3000 sizes for pools up to 100,000 litres in a temperate climate. It has a timer with battery backup, a self cleaning cell, and salt level and no flow protection, and it works on pool salt or Waterco Mineral Crystals.

Ideal for

• Standard domestic pools up to 100,000 litres
• Owners who want chlorine and a timer without extra control features
• Replacing an older salt chlorinator
• Pools that run on pool salt or Waterco Mineral Crystals

Key Specs

• Hydrochlor ST 2000: 20 g/hr chlorine, pools up to 60,000 litres in a temperate climate (48,000 litres tropical), 105 W, 5.4A DC output
• Hydrochlor ST 2500: 25 g/hr chlorine, pools up to 80,000 litres in a temperate climate (60,000 litres tropical), 115 W, 5.8A DC output
• Hydrochlor ST 3000: 30 g/hr chlorine, pools up to 100,000 litres in a temperate climate (72,000 litres tropical), 130 W, 6.0A DC output
• Power: 170 to 264V, 47 to 64 Hz input, 10A maximum total current, 8A maximum for the pump outlet, 21V cell voltage, IP23
• Salinity range: 4,000 ppm minimum, 5,500 ppm optimum, 6,000 ppm maximum
• Salt: runs on ordinary pool salt, or Waterco Mineral Crystals. Waterco's rule of thumb is about 1 kg of salt per 1,000 litres to lift the level by 1,000 ppm, so 420 kg takes a 70,000 litre pool from nothing to 6,000 ppm. Use pure pool salt with no additives
• Power pack: switch mode technology, which Waterco says is over 50% more efficient, and it senses the size of the connected cell and adjusts its output
• Cell: self cleaning, reversing polarity to clear calcium build up, 13 plates on the standard versions
• Protection and control: salt level alarm that limits output if salt is too high, no flow detection with an LED indicator, easy to use timer with battery backup, LED indicators
• Versions: standard cell or premium cell. Premium cell versions carry a premium salt cell. Waterco lists its premium salt cells with a 4 year warranty against 3 years for a standard 13 plate cell, and does not publish more on the difference, so ask us if you want to know whether it matters for your pool
• Sizes 1000 and 1500: not listed here as Waterco publishes no specs for them

Why We Like It

A no nonsense chlorinator that does the job without the extras. If you want it to control your pump or lights, step up to the Electrochlor ECO. Pick the size from your pool volume, and go up one if the pool sits in full sun or is heavily used, as the volume limits are for a temperate climate. The premium cell costs more, so ask us whether it makes sense for your pool.

Installation

The cell plumbs into the pool return line and the power pack mounts on a wall near the pump, with the supplied cabling between them. Fit it yourself, or use a pool installer or plumber. The power pack needs a licensed electrician to connect to a fixed supply.

Warranty & Support

3 year warranty on the power pack and 3 years on the salt cell, conditional on the install and use following Waterco's terms. Commercial installations are covered for 1 year. Waterco lists its premium salt cells at 4 years against 3 for a standard cell. DIY installing? Warranty applies when the install follows the supplied install guide. Questions?
