COVID-19 Disinfection Process

  • Defence Research and Development organization (DRDO) .
  • Developing several solutions from its existing arsenal of technologies and experience.
  • DRDO has introduced two products which can enhance the operations at public places during the pandemic.

Automatic Mist-Based Sanitizer Dispensing Unit

  • Centre for Fire Explosive & Environment Safety (CFEES) , Delhi along with HPO 1.
  • Economical and long lasting product.
  • Easy to install system as wall-mountable or on a platform.
  • The unit can be used for sanitization of hands at entry and exit to hospitals, malls, office buildings, residential buildings, airports, metro stations, railway stations, bus stations and critical installations along with the quarantine centres.
  • Expertise in mist technology for fire suppression, has developed automatic mist based sanitizer dispensing unit.
  • It is a contactless sanitizer dispenser which sprays alcohol based hand rub sanitizer solution for sanitization of hands while entering the buildings/office complexes, etc.
  • It is based on water mist aerator technology, which was developed for water conservation.
  • The unit operates without contact and is activated through an ultrasonic sensor.
  • This sanitizes the hands with minimum wastage and it gives the full cone spray over both palms so that disinfection operation of hands is complete.

UV Sanitization Box and Hand-held UV Device

  • Defence Institute of Physiology & Allied Sciences (DIPAS) and Institute of Nuclear Medicine & Allied Sciences (INMAS) , DRDO laboratories in Delhi.
  • Environment friendly and a contact free effective sanitization method.
  • Designed & developed Ultraviolet C Light based sanitization box and hand held UV-C (ultraviolet light with wavelength 254 nanometres) device.
  • Consists of a shorter, more energetic wavelength of light.
  • Good at destroying genetic material in COVID-19.
  • The radiation warps the structure RNA which prevents the viral particles from making more copies of themselves.
  • COVID-19 virus will be deactivated by using UVC lamps in one minute placed equip-distantly in a box with UV dose of .
  • The UV lamps used in the sanitization box also emits 185 nm which produces ozone.
  • Able to take care of the unexposed area on the surfaces of the objects placed in the box.
  • Hand held device.
  • Eight watt UV-C lamp disinfects office and house hold objects like chairs, files, postal delivered items and food packets with an exposure of 45 second at irradiance placed at a distance of less than two inches.
