About Otsil

Established Formed in 1994, Ozone Technologies and Systems India Pvt Ltd (OTSIL) has been at the forefront of the ozone revolution in India.

Since introducing India to ozone, OTSIL has been working with the world’s leading ozone experts for over 25 years to tackle water and waste water problems unique to India. From simple applications like potable water treatment, to complex solutions for paper and pulp bleaching; from lab-scale ozonators to the largest ozone generators in the world (200 kg/hr at ITC Badrachalam) from recycling municipal waste water for industrial use, to treating nuclear power plant cooling water; OTSIL’s expertise has helped treat more water and waste water than all ozone manufacturers in India combined.

Our strength has been to view each application in its totality. We stand apart because our ozone applications are supported by committed ozone consultancy, excellence in ozone engineering, and dependable after sales services.
