Our Story

In the last 30 years, Ozotech has established itself as a major manufacturer of ozone generation equipment. Our success is based on a number of factors: constant improvement of technology and manufacturing processes, high employee satisfaction and retention rate, our commitment to “green” technology, and our dedication to quality.

Our patented cold spark corona discharge technology represents the latest in state-of-the-art ozone generation. Every ozone cell is handmade right here at our local glass shop in Yreka, California, and our units are reliable enough to stand up to rigorous field conditions in places like Saudi Arabia, Ukraine, Bangladesh, South America, North Africa, Europe, South East Asia and Australia.
