Ambiator deploys refrigerant-free cooling units across eight Indian cities
3 articles · Updated · The Better India · Apr 28
More than 35 units are operating in Hyderabad, Warangal, Bangalore, Jaipur, Delhi, Vellore, Pune and Panchgani, supplying 24-28°C fresh air even above 45°C outdoor heat.
The Hyderabad startup says each unit uses about 1 kilowatt, around 6.5 times less electricity than comparable conventional air conditioning, with no compressors, refrigerants or recirculated stale air.
Founded in 2022, Ambiator is targeting factories, hospitals, offices and homes, while exploring data-centre pre-cooling and 5,000 off-grid heat shelters to cut emissions and public infrastructure costs.
Could traditional air conditioners, with new green innovations, surpass Ambiator’s evaporative cooling in both efficiency and environmental impact?
How does Ambiator’s technology handle India’s humid monsoon seasons, and what barriers could prevent its widespread adoption?
