Professional Quality Chlorine Dioxide Services Globally
DIOX eChem Chlorine Dioxide
The DIOX eChem Series is designed to produce a powerful pure Chlorine Dioxide (ClO2) solution, safely, efficiently, reliably and economically, using only Sodium Chlorite, water and power as the raw materials. Acid is not required. DIOX Machines are manufactured in Australia by Water Engineers with outputs ranging from 50 – 2,000 g/hr.
The Chlorine Dioxide molecule is relatively small, volatile, and very energetic – a free radical. It is stable in dilute solution, but unstable in concentrated form. Thus, chlorine dioxide is almost always used as a dissolved gas in water in concentrations that range from 50 to 5,000 ppm. Because transportation of concentrated chlorine dioxide is not safe, chlorine dioxide is almost always produced on site.

ClO2 is a highly effective biocide that kills bacteria, viruses, algae, fungi and protozoa. Used properly, ClO2 has little or no effect on human, animal or fish cells and is safe to use.
ClO2 is unsurpassed in its disinfection capabilities throughout water systems, also in “dead end” areas. For this reason, ClO2 is often used to disinfect chilled water, municipal water systems and hot and cold water systems in hospitals and healthcare facilities, where bacteria such as Legionella can prove to be stubbornly resistant to other biocides, chlorine in particular.
Furthermore, chlorine dioxide does not affect taste or form toxic chloramines or haloforms (THM). This is a characteristic that makes ClO2 ideal for flavour sensitive applications such as wine and brewing.
THE PROCESS
The single precursor eChem Chlorine Dioxide generation process electrolytically converts Sodium Chlorite to Chlorine Dioxide gas in the patented OxiMax CDE cell. This gas is then stripped from the solution in the patented vClone and then dissolved in water to be stored in the Solution Tank at a level of up to 2,000 ppm.
Recirculation of solutions optimises efficiency and minimises power consumption to allow outstanding performance from a compact machine.
The process is safe, reliable and is controlled by a microprocessor, which continuously monitors the performance of the machine, makes the appropriate decisions and displays the status via the LEDs and on an LCD screen.

Several DIOX eChem models are available, with outputs up to 2,000 g/hr. All DIOX machines use a single chemical precursor, either 25% or 31% Sodium Chlorite, with no acid or chlorine needed.
The heart of the DIOX Series is the patented DIOX Cells, which consist of computer optimised waterways, long life Titanium SC12 anodes and Titanium cathodes. Aluminium backing plates are used on each side of the cell, to give strength and ensure optimum cooling.
Remote communication, dosing pumps, dosing control equipment and a range of options allow each machine to be customized to suit the particular application.
