JBJS – Ultraviolet Lighting During Orthopaedic Surgery and the Rate of Infections
All procedures that were performed before the installation of the ultraviolet lighting used horizontal laminar airflow, whereas all procedures that were performed after that date used ultraviolet lighting without laminar airflow. Factors associated with the rate of...
Guidelines for Design and Installation
The International Ultraviolet Association (IUVA) Draft Guidelines for UVGI Air Treatment Systems are international voluntary guidelines developed under the auspices of the IUVA. This consensus represents a substantial agreement reached by parties in Academia and...
Design and Optimization of UVGI Air Disinfection Systems
Mathematical models of the response of populations of microorganisms exposed to ultraviolet germicidal irradiation (UVGI) are developed that include two-stage response curves and shoulder effects. Models are used to develop a C++ computer program that is capable of...
Dimensional Analysis of UVGI Air Disinfection Systems
A dimensional analysis of ultraviolet germicidal irradiation (UVGI) air disinfection system within a diffusely reflective enclosure is performed using the Buckingham pi theorem. The eight dimensionless parameters obtained include the duct aspect ratio, the lamp aspect...
The Best Way to Improve Indoor Air Quality
Heating, ventilation and air conditioning (HVAC) systems are the perfect breeding ground for bacteria, viruses, pathogens, spores, molds, and more. Air recirculation, temperature fluctuations, and humidity within these systems promote the growth and distribution of...
CDC Updated Guidance
Consider using ultraviolet germicidal irradiation (UVGI) as a supplemental technique to inactivate potential airborne virus in the upper-room air of common occupied spaces, in accordance with industry guidelines.
How air pollution is causing a rise in coronavirus deaths
It is a well-known fact that air pollution can cause problems with your breathing and respiratory system, and recent research has shown that it is also impacting the severity of COVID-19 symptoms. The study by the IZA Institute of Labor Economics in the Netherlands...
MASKS’ DECONTAMINATION WITH UV-C/UVGI: RISKS AND OPPORTUNITIES
UV-C/UVGI - has been successfully tested in laboratories as a way to decontaminate N95 masks exposed to MS2 bacteriophage and influenza virus. In recent weeks our distribution network in the healthcare sector is working non-stop. Our partners are professionals...
UV – C efficacy against Coronaviruses, (COVID-19, SARS – MERS)
Our company has always been committed to reducing the risk of contamination and increasing safety by managing cross transmissions in many areas: surface treatment, air quality, and water disinfection. UV-C is an established and reliable technology, but solid know-how...
