Dontek Ioniser PWP2 Fresh Water Purifiter – The Dontek Ioniser has been designed to reduce chlorine or bromine usage to a minimum. A saving of up 70% can be expected in a typical installation.

The PWP2 is a swimming pool, spa and pond ioniser that controls the filter, pump run times and current output to the copper and silver alloy electrodes. The battery backed up clock controls multiple filter and ionising times as well as auto winter and turndown modes. The PWP2 is designed to suit pools up to 100,000 litres.

These work by producing Silver & Copper ions in pool or spa water. The Copper ions are effective as an algaecide and the Silver ions are an effective bactericide. 

The cell contains 2 alloy electrodes made of copper and silver and are supplied in a transparent polycarbonate cell enclosure. The cell is supplied with both 40mm and 50mm adaptors and barrel unions for connection to pool plumbing. (Directly Replaces Astralpool & Hurlcon chlorinator cells).

The unit allows for a DC ionizing current from 50 milliamps up to 400 milliamps in eight steps of 50 milliamps,which caters for small up to large pools. The polarity is reversed every 3 minutes so that both electrodes wear evenly and their life expectancy in a correctly balanced pool is around 3 years. The unit has a time clock which, along with the filter and ionizing times, can be set by the customer.
