Davey Chloromatic DNP25CLS Nipper 25g Low Salt Chlorinator

This low-salt Davey ChloroMatic Nipper combines strong chlorine production with the comfort of reduced pool-water salinity. Producing up to 25 grams of chlorine per hour, it is suitable for residential in-ground and above-ground pools up to 100,000 litres in cooler climates.

The system can operate from just 1,500ppm salt, making it suitable for low-salt and compatible mineral pools. Its digital controller, independent timers and intelligent operating modes provide flexible pool management, while the reverse-polarity cell helps reduce calcium scale accumulation.

Key Features

• 25g/hr chlorine output for medium to large residential pools.
• Low-salt operation from 1,500ppm for reduced pool-water salinity.
• Salt and mineral compatible across an operating range of 1,500–6,000ppm.
• Reverse-polarity cell helps minimise calcium scale accumulation.
• Adjustable output in 5% increments for accurate chlorine control.
• Two independent timers provide flexible daily filtration schedules.
• Digital LCD display clearly shows settings, operating status and alarms.
• Add Salt, Low Salt and Low Flow alarms help protect the chlorinator.
• Integrated safety flow switch stops chlorine production if adequate water flow is not detected.
• Battery backup protects programmed settings during power interruptions.
• Energy-efficient switchmode power supply in a UV-stabilised enclosure.
• 36-month manufacturer warranty for added peace of mind.

Intelligent Operating Modes

• Boost Mode: Runs at maximum output for 24 hours following heavy swimming, contamination or extreme weather.
• Cover Mode: Reduces chlorine production while the pool is covered.
• Spa Mode: Reduces output for smaller water volumes.
• Winter Mode: Reduces cell output during periods of lower chlorine demand.

Pool sizing is a guide only. Actual requirements depend on climate, water temperature, pool use, sunlight, filtration runtime and water chemistry. The correct salt concentration must be maintained to protect the electrolytic cell.
