One of the Council of Scientific and Industrial Research’s (CSIR’s) premier engineering lab based in Durgapur, CSIR-Central Mechanical Engineering Research Institute (CMERI) has developed technologies and products, which can help in countering the menacing virus.
The Disinfection Walkway can be considered to be one of the most comprehensive Disinfectant Delivery Systems available. The Walkway ensures maximum target coverage with minimum shadow area of an individual. The Disinfection Walkways can be deployed at multiple critical locations such as Isolation/Quarantine facilities, Mass Transit System Entry points, Medical Centres and any other location with a considerable amount of footfall.
Two variants of the Disinfection Walkway developed by CSIR-CMERI are:
Pneumatic Variant Disinfection Walkway
This variant of Disinfection Walkway deploys Six Bar pressure Air Compressor to ensure optimum mist formation. The embedded sensors of the Walkway ensure that the operational time of the system can be varied within a range of 20 seconds to 40 seconds. Though the initial cost of this variant is relatively higher, the operating cost of this system is much less, owing to optimum usage of disinfectant in this system. This has been installed at CMERI and the dimensions of the Walkway at the CMERI Institute Main Gate are 2-m height by 2.1-m length and 1-m width.
Hydraulic Variant Disinfection Walkway
It deploys 1 hp pressurised motor High Velocity pump with necessary set up nozzles to ensure optimum mist formation. The initial cost of this variant is relatively lower. The embedded sensors of the Walkway ensure that the operational time of the system is just within a range of 20 seconds to 40 seconds. This variant of Disinfection Walkway has been installed at the CMERI Medical Centre.
Road Sanitizer Unit
The CSIR-CMERI Road Sanitizer Unit is a tractor-mounted Road Sanitizing System. This Road Sanitization unit can be effectively deployed in long stretches of highways, vicinity of toll plazas etc, where there is a massive volume of traffic and higher chances of infection spreading. It can also be deployed in Housing Complexes, Office Complexes, Sports Arenas, Apartment buildings etc.
The Road Sanitizer has a span of 16 feet, which uses 15 to 35 bars of pressure to ensure effective delivery of the sanitizer. 12 nozzles are used to ensure optimum radial coverage of sanitizer. The system utilizes a 2000 to 5000 litres tank with a pump of 22 LMP which can be used to sanitize a road stretch of up to 75-km.
