📋 Tender Overview
There has been increasing evidence for airborne route of transmission of SARS-CoV-2 via aerosols which is now considered to be important by international agencies WHO REHVA ASHRAE and by health authorities in several countries. The airborne transmission is a major risk in indoor settings. Significantly research carried out by CSIR constituent labs Centre for Cellular and Molecular Biology CSIR-CCMB and CSIR-Institute of Microbial Technology CSIR-IMTECH in September 2020 had demonstrated experimentally that SARS-CoV-2 viral particles could be detected in air even after 2 hours of exit of infected persons from a room and at distances much greater than a few meters as wellS C. Moharir et al.2020strengthening evidence of airborne transmission of the SARS-CoV-2. httpswww.medrxiv.orgcontent10.11012020.12.30.20248890v1Based on these studies and recognizing the need for effective solutions of viral disinfection the challenge was to develop an effective fail-proof retro-fit device with high intensities to handle fast airflows to be fitted with minimal intervention in air-ducts of existing HVAC systems that are widely used in indoors in industrial and commercial environment. CSIR-CSIO has developed an UV-C air duct disinfection system. The disinfection system can be used in auditoriums large conference rooms classrooms malls etc. which will provide a relatively safer environment for indoor activities in the current pandemic. The technology has been developed according to the requirements for deactivation of SARS COV-2 virus contained in an aerosol with necessary ventilation measures necessary safety and user guidelines and tested Bio-safety standards etc. UV-C deactivates over 99 of viruses bacteria fungus and other bio - aerosols etc. with appropriate dosages using 254nm UV light. Use of UV-C may also help in ameliorating the fungal infections being witnessed during the current wave of the pandemic.The CSIR-CSIO developed product is tested for more than 99 disinfection and could be used as a retrofit solution to Air Handling Units AHUs of buildings transport vehicles and other spin off applications. The UV-C is energy efficient system improves airflow through coils enhances indoor air qualityrequires less maintenance easy to retrofit with any existing system having AHU ducts and has low initial setup cost. The system comes with commercialized standards and certifications.CSIR-CSIO has transferred the technology to the following companiesAarco Engineering Projects Pvt LtdFlexatherm Expanllow Pvt. Ltd.
