Product Description

Vayujal (VJ-400 Lpd Unit) is a 400-liter water harvesting and purifying device that extracts water from atmospheric humidity. It aims to solve the global water shortage problem by utilizing abundant water molecules in the air. The device is also known for atmospheric water generators (AWGs) and is commercially available. It was designed by Ramesh Kumar, Ankit Nagar, and Prof T Pradeep as a startup in IIT Madras, India. It uses an 8 stage water purification system before it reaches the consumer and meet the WHO drinking water standards.

Design Specifications

Vayujal (VJ-400 Lpd Unit) is an air-water generator that produces 400 Liter of water a day by extracting water from atmospheric humidity. The patented technology utilizes nanotechnology like bio-mimetic to make evaporators and condensers. The working mechanism of the technology follow five simple steps; The air is filtered after fresh humid air is sucked in through a vent. Then water is collected in the stainless steel water tank after it is condensed on a bio-mimicked surface. Hot air is released back into the atmosphere after the water molecules are extracted. The collected water then goes through an eight-stage filtration process to meet the drinking water standards of the World Health Organization (WHO) & Bureau of Indian Standards (BIS). Lastly, in order to ensure the purity and pH levels stability, essential minerals are added which are then ideal for human consumption. Some of the design specification for the device is as follow: Dimensions: (90 x 100 x 160)cm Net weight: 360 kg Power rating : 5 kW at 70 %RH and 30 0Celcius Refrigerant: R410A Power supply: 380 Vac, 3 Phase, 50 Hz Noise level (dB)< 65 Air Purification: Al mesh supported HDPE fabric
