DRDO develops ‘Ultra Swachh’ for disinfection of PPEs and other materials

India’s one of the most premier organisations, Defence Research and Development Organisation (DRDO), has developed a disinfection unit named “Ultra Swachh” to disinfect a wide range of materials, including Personal Protective Equipment (PPEs), electronics items, fabrics, etc. Institute of Nuclear Medicine & Allied Sciences (INMAS), the Delhibased laboratory of DRDO, has developed this product with industry partner M/s Gel Craft Healthcare Pvt Ltd, Ghaziabad.

Explaining about this development, DRDO spokesperson Narendra Kumar Arya told The Daily Guardian, “The disinfection of medical equipment especially Personal Protective Equipment is an essential requirement for infection control practices world-wide. During Covid-19, surge of continuous requirement of PPE and with global closure, it requires to be developed indigenously.

With time, the countries even with unlimited financial resources started contingency planning for re-use / multiple use of PPEs. The re-use of PPEs requires “cost-effective ‘fabric safe’ disinfection system”. Accordingly, Ultra Swachh PPE Disinfection System was developed at INMAS DRDO.” The system is in compliance with International Standards of Industrial, Occupational, Personal and Environmental Safety. The Ultra Swachh comes in two variants namely Ozonated Space and Trinetra Technology. Trinetra technology is the combination of Ozonated space and radical dispenser. Treatment is optimised with automation for quick disinfection cycle.

HOW IT WORKS The system uses an advanced oxidative process comprising of multiple barrier disruption approach using Ozonated Space Technology for disinfection. The system is double layered with specialised Ozone sealant technology assuring trapping of ozone for the necessary disinfection cycle. It also has catalytic converter to ensure environment friendly exhaust i.e. only oxygen and water.

The system operates on 15 Ampere, 220 Volts, 50 Hertz power supply. The system has been provided with various safety features such as emergency shutdown, door interlocks, dual door, delay cycle, and leak monitors, etc, to ensure safe operations for longer duration. Dimensions of the Industrial Cabinet are 7’x4’x3.25’ to disinfect large quantity at a time. Cabinets of different sizes will be available for the industry.
