Davey Chloromatic DNP25C Nipper 25g Salt Water Chlorinator

The Davey ChloroMatic Nipper offers reliable automatic chlorination for medium to large residential salt and mineral pools. With a chlorine output of up to 25 grams per hour, this complete system is suitable for in-ground and above-ground pools up to 100,000 litres in cooler climates.

Its user-friendly digital controller provides two independent timers, adjustable chlorine output and dedicated modes for seasonal or changing pool conditions. The reverse-polarity cell helps reduce calcium build-up, while integrated salt and flow protection provide added confidence during everyday operation.
