It is scientifically proven that Ultraviolet Germicidal Irradiation (UVGI) kills all bacteria, spores, viruses, protozoans, moulds and yeasts. The level of UV irradiation in our cabinets will kill 99.9% of Poliovirus 1, SARS, H-CoV 229E , H-CoVOC43, H-CoV 229E, Influenza A (H1N1), Covid 19 in under one minute of exposure (*ref.: M. Buonanno, D. Welch, I. Shuryak, D.J. Brenner; DOI: 10.21203/ rs.3.rs -25728/v1), (*ref.: Tree et al. 2005), (*ref.:CDC, 2020) . The longer the exposure, the higher the log reduction achieved (see “What is log kill” below).

Yes, completely safe. Our cabinets are designed in a way that no radiation will escape. We can back this up with an IEC 62471 Photobiological Safety certificate. We are in the Exempt group – the highest safety standard. Additionally all cabinets are equipped with a door safety switch preventing accidental light exposure (in case the doors are opened during a sanitisation cycle).

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UVC) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification.

CE, RoHS, IEC 62471, Electromagnetic Compatibility/Low Voltage Directive, ISO 9001, ISO 14001, Sterilisation Efficacy Evaluation certificate.

In addition, UV Cleantech in Australia have conduced UVC level tests testing all areas of the cabinets to confirm UVC levels.

Yes, our testing data and official lab reports in full are available on request.

SafeWork Australia defines a safe exposure limit for ozone at 0.1 ppm (Time Weighted Average Exposure over 8 hour working day). Other countries apply similar or the same standard. Our lamps’ combined production is very small – 0.07 particles per million (measured inside of the cabinet at the maximum concentration). Ozone is an excellent disinfectant and in our cabinets adds to the sanitisation effect. The air containing ozone is extracted by a specially designed filtration system, which turns O3 into O2 (the same oxygen we breathe). Concentration after the catalyst filter is negligible. UV sanitation in comparison to various chemicals is far cleaner and more environmentally friendly. Most importantly, it does not leave any residue on disinfected surfaces.

No liquids and no living creatures are allowed inside our cabinets. Other than that, almost every commonly used item which needs surface disinfection can be cleaned. Metals, various plastics and materials, cardboard, and rubber surfaces can be effectively sanitised in our cabinets.

We have done excessive stress testing with various headsets and other popular electronic devices (mobile phones, tablets etc) simulating 1.5 years of standard usage (significantly more than any device would be exposed to in its lifetime). We observed no impact of the UVC radiation either on appearance or function.

Yes, Uvisan cabinets come with a 1-year warranty from the day of delivery. Most importantly, we offer full warranty and maintenance support here in Australia.

All the electric and electronic devices are protected by circuit breakers and a RCD module. Also during normal operation the temperature inside the cabinet is in the region of between 20 and 30 degrees Celsius. Additionally the cabinet is made of non-combustible materials (mostly steel).

10 kg per shelf is the maximum we recommend.

Log Kill (also known as Log Reduction) is a widely used measure describing how well the process of decontamination eliminates a contaminant. It is determined by measuring the number of living microbes eliminated when the decontamination process is complete. The higher the Log Reduction, the more thorough the decontamination. By eliminating 99.99% of living microbes, Uvisan products achieve a Log Kill of 4. Most importantly, this has been tested to occur over all areas of the cabinet providing 360 degree device coverage.

The table below shows the level of contaminant reduction in each level of Log Reduction.

Height is adjustable – each shelf can move up and down by 4cm. Due to the modular construction shelves can also be removed for use with larger/taller devices. The standard vertical clearance between the shelves is 20cm, maximum clearance (with two shelves adjacent) is 28cm.

Yes. All Uvisan products come with a 1-year warranty. If your Uvisan product is defective in any way, please contact customer service on help@uvcleantech.com. 

It is specific to the lamp – an electric discharge produces UV radiation in a very narrow band (peak exactly at 254nm). There are also small “sidebands” produced in a visible range (over 400nm) – this is the pale blue colour characteristic to all UVGI lamps.

Lamps offer almost constant UV output over their complete lifetime, for maximum security of disinfection and high system efficacy – always 254nm. Lifespan of our lamps is 9000 hours. 

Yes, in fact as an integrated storage, charging and cleaning solution this is expected. The UVC cleaning cycle will switch off automatically when completed, leaving the devices to charge in lockable storage.

Small 200W
Medium 250W
Large 330W

Uvisan cabinets can also be battery powered via a UPS (Uninterruptible Power Supply)
