Si-Zone® ultraviolet ozone generators
Si-Zone is our own UV ozone generator, the heart of every Garbage Doctor®. Si-Zone makes ozone with ultraviolet light, so Si-Zone makes no nitrogen oxides and causes no nitric acid corrosion, and Si-Zone is built to run 24/7 in a bin room.

Why we developed Si-Zone®
Our Si-Zone ultraviolet ozone generators were born from the need for a high-quality, reliable ozone generator for garbage odours that wouldn't corrode the chute. When we developed Si-Zone, the Garbage Doctor was the only system from a major supplier in Australia that met those aims, without the corrosion that had damaged so many buildings' chutes.
The technology is our own, and part of our intellectual property. Years of experience in bin rooms have made Si-Zone, in our view, the most reliable system of its kind in the Australian market. Every one of our commercial ozone generators is rated for continuous 24/7/365 operation.
What makes Si-Zone® different
- Proven over many years in buildings throughout Australia and New Zealand.
- Built for 24/7 use in rooms high in dust, moisture and airborne contaminants.
- High ozone output, adjustable in very fine steps, so each installation is set for the site.
- Free from nitrogen oxides, and so from the nitric acid that corrodes steel.
- High fan pressure models, for ozone through long runs of conduit, so the ozone can be targeted further from the machine.
- Engineered and built to Australian and New Zealand standards.
Our UV ozone generators have been installed with chutes, bins, carousels and compactors from all manufacturers, including Elephants Foot, WasteTech, JJ Richards, Wanless, James Hardie and JD MacDonald, and our technicians install and service them throughout Sydney, Melbourne, Brisbane, the Gold Coast, the Sunshine Coast, Airlie Beach, Tweed and Auckland.
