Company History
We embarked on our journey in the year 1963 with the commissioning of our first air separation plant at Pune in Maharashtra, India. Over the years we have successfully expanded our presence across India while manufacturing and supplying industrial gases and specialty gas mixtures. At the turn of the millennium, we strengthened our leadership position with strategic collaborations.
In 1999, the INOX Group joined hands with Air Products and Chemicals Inc., USA, to establish a joint venture company INOX Air Products that emerged as one of the largest manufacturers of Medical and Industrial Gases in India. With a dedicated and a highly motivated Team, integrity in the way we do business and a passion for exceeding expectations, we work to develop lasting relationships with our customers and empower communities that exist around us.
1960s
| In the 1960s, Sri Devendra Kumar Jain, a History Honours graduate from New Delhi’s prestigious St. Stephen’s College, decided to go beyond the trading business and become an industrialist. He saw great promise in the business of extracting, liquefying and selling gases from natural air, as these industrial gases were widely used in the steel, manufacturing and healthcare sectors – all of which were flourishing in India at that time. He established Industrial Oxygen Company Private Limited in Maharashtra in 1963. |
