Alfaa UV recently introduced STERO-360, a high-performance mobile UV sanitiser, to address the rising demand for hassle-free touchless and non-chemical disinfection solution especially during the COVID-19 pandemic.
As per a release, STERO-360 uses Ultraviolet Germicidal Irradiation (UVGI) disinfection method in which the sanitiser emits short-wavelength ultraviolet (ultraviolet C or UV-C) light to inactivate microorganisms by disrupting their DNA, hence destroying the ability of the microorganisms to reproduce and thereby effectively killing them.
The release cites global clinical studies which reportedly mention that UV-C light can combat the novel coronavirus as UV-C falls in the range of 200nm to 280nm of the ultraviolet light spectrum, which is known to eradicate micro-organisms, viruses, bacteria, yeast, molds, fungus, etc., in air and on surfaces. The chemical-free technology is known to kill 99.99 per cent of all pathogens with no residue or by-products.
An organism must receive the correct UV dose for it to get inactivated. The mean UV-C dose requirement for the coronavirus group of organisms (of which COVID-19 is a part) is 26,000 uW-sec/cm2 for a 4 log (99.99 per cent) kill rate. STERO-360 is designed to provide a 50,000 uW-sec/cm2 dose to a target surface at a distance of 1.8 meters and height up to 2.5 meters within 2.5 minutes.
Ergonomically designed, STERO-360 exhibits six high-intensity UL certified UVGI emitters that are ozone free, proprietary high-efficiency energy distribution system to increase the irradiated UV dose on target surfaces by > 100 per cent. Its real-time performance validation with NIST/ US FDA approved PRISM technology ensures complete sanitation every single time.
STERO-360-6900 comes equipped with app-based control for remote operation; preset functionality which ensures that the device is placed in the ideal location in a room every time – eliminating operator error. The device also showcases data logging with a web interface for verification and audit trail.
