As sanitising public spaces becomes a major task for the authorities in the battle against coronavirus, the Defence Research and Development Organisation (DRDO) has come up with two solutions—-spin-offs from technologies developed for fire suppression applications–for sanitising areas of different sizes. The DRDO has already provided two of these systems to Delhi Police for immediate use.
The first solution is a portable sanitisation equipment for spraying decontamination solution consisting of one per cent Hypochlorite (HYPO) solution for sanitisation of suspected area. This portable system can be mounted as a backpack and can be carried by the operations personnel.
This system incorporates low pressure twin fluid (air & disinfectant liquid) technology to generate very fine mist. The system is capable of disinfecting upto 300 square metre area. The application areas can include hospital reception, doctor chambers, office spaces dealing with general public, corridors, pathways, metro and railway stations and bus stations.
The second solution is a trolley-mounted large area sanitiation equipment. The system incorporates low pressure single fluid (disinfectant liquid) technology generating very fine mist. It is capable of disinfecting upto 3,000 square metre area.
It has a tank capacity of 50 litres and has a throw distance of 12-15 metres. This is useful for disinfecting hospitals, malls, airports, metro stations, isolation areas, quarantine centres and high risk residential areas.
