SLT-Series disinfection technology uses Ultra-Violet light in the germicidal wavelength range between 200 and 300 nanometers. The optimum UV wavelength for UV disinfection is 264 nanometers which is located within the UV-C spectrum. When microorganisms are exposed to germicidal wavelengths, they are destroyed outright or rendered incapable of reproducing. The high energy associated with UV-C UV light is absorbed by the DNA of bacteria, viruses, spores and other pathogens. This absorption causes abnormalities within the DNA to occur, resulting in the microorganism being incapable of reproducing and infecting.

UV Guard Applications

Our market-leading UV disinfection systems deliver outstanding results across an extensive range of industrial, commercial and domestic applications.


The HWC-Series took a few weeks to clean the calcium build-up from the pipes and the results were astonishing. I honestly cannot speak more highly of the product and installation was so easy.

Since installing the water conditioner we are using less washing powder, soap and shampoo. The life of our hot water element also appears to have been extended.

Sally, WA

Since installing our Shower Water Conditioner, the whole family has noticed the difference. We all have softer, more manageable hair and my son no longer has as many skin irritations.

Allison, NSW

Before installing UV-Guard’s Hard Water Conditioner, Calcium used to build-up on every surface, Iron was also staining our toilets and basins. Now there is no Calcium build-up and the Iron staining is easily wiped away.
