Ioniser Dontek PWP2 for swimming & spa pools

Dontek Ioniser PWP2: Precision Ionisation for Swimming & Spa Pools

The Dontek Ioniser PWP2 is a precision-built ionisation system designed to dramatically reduce chemical use while delivering sparkling, balanced water for both swimming pools and spas. By pairing copper-silver alloy electrodes with intelligent control, it provides continuous sanitisation without relying on traditional chlorine chemicals.

How it works

• Two robust electrodes made from a copper-silver alloy sit inside a transparent blue polycarbonate cell. As water flows through, copper ions act as a powerful algaecide and silver ions provide bactericidal action, delivering ongoing sanitization without conventional chlorine.
• The unit delivers a DC ionizing current from 50 to 400 milliamps in eight discrete steps, allowing you to scale from small domestic pools to larger setups.
• To maximise electrode life, the polarity is reversed every 3 minutes, distributing wear evenly and extending service life to around 3 years in a correctly balanced pool.

Smart control and scheduling for effortless maintenance

• Real-time clock and a suite of presets automate filtration and ionisation for reliable, hands-off performance: 8 preset filter duration cycles, 7 preset start times, and 7 preset ionising times.
• Ionising runs only while the filter pump is active, ensuring water is flowing through the electrode cell and aligning ionisation with your filtration schedule.
• The system automatically restricts ionising time to stay within the chosen filter run time, preventing misuse and preserving energy.

Installation and compatibility

• Designed for straightforward integration with standard pool plumbing. The ioniser ships with both 40mm and 50mm adaptors and barrel unions for easy connection to your piping.
• A simple cable with two eye terminals connects to the electrodes via brass wing nuts, making installation simple and secure.
• The compact, transparent-blue cell is easy to monitor and built for durability, with an anticipated life of about 3 years in balanced water conditions.

Real-life benefits that matter

• Chlorine-free operation: dramatically reduces chlorine or bromine usage, with typical installations achieving up to 70% chemical savings.
• Energy-efficient sanitisation: lower power draw than traditional salt-based chlorination while maintaining effective cleaning and disinfection.
• Protects equipment and surfaces: by reducing reliance on salt-based sanitizers, it helps minimise salt-induced corrosion on pumps, heaters, and surroundings.
• Asthma-friendly water: gentler chemistry for swimmers with sensitivities, without compromising cleanliness.
• Versatile and scalable: suitable for both pools and spas, with performance that adapts from compact spas to larger family pools.

Who should consider the Dontek Ioniser PWP2?

Homeowners looking to lower ongoing chemical costs, individuals with swimmers sensitive to traditional sanitizers, and anyone seeking easier pool maintenance without sacrificing water quality will appreciate the PWP2. It’s especially well-suited for balanced-water enthusiasts who want predictable performance with automated scheduling and minimal manual dosing.

Why ionisation matters

Choosing ionisation over conventional chemical dosing offers tangible, practical advantages: fewer chemical additions, more consistent water balance, and a simpler maintenance routine. With the Dontek PWP2, you gain reliable sanitation, extended electrode life, and the peace of mind that comes with automated, scheduled operation.

Maintenance and longevity tips

To maximise performance and life expectancy, keep water balanced and ensure adequate water flow through the electrode cell. Expect around a three-year service life under balanced conditions, with periodic checks on the polarity reversal system and the integrity of connections at the adapters and terminal points.
