Parts & Service for
Hess Machine Equipment

About Us

Starting in 1965, Hess Machine International became the bottled water industry's leading supplier of ozone purification systems. That leadership is the result of having both the highest quality equipment and the individualized service that met each customer's specific requirements. Hess Machine International was America's most popular bottled water purification system with more installations in the USA than any other brand, serving over 35 countries internationally as well.

We're proud of Hess Machine's 30+ year history. Hess Machine pioneered the use of ozone in bottled water applications and developed the experiences we all rely on today.

The Ozone Generators developed by Hess Machine were some of the most reliable, robust options available and still remain excellent options for bottled water and other water treatment applications. The simple design using robust parts is still sought after and desirable, especially in remote areas where servicing more complex ozone generators is not a viable option. If you still have, or are looking to implement a Hess Machine ozone system you should rest easy that you are using one of the most reliable ozone generator designs in the history of industrial ozone use.

Today, Hess Machine has ceased production of new Ozone Generators.
However, Parts, Service, and long-term support is still available.

Oxidation Technologies has worked with Terry Good, a long-term and last employee of Hess Machine to source, and inventory every major replacement part needed for long-term service of all Hess Machine ozone generators.

Today, ozone has many expanded uses. Ozone is used in process water disinfecting, food processing, public water systems, waste treatment, petrochemicals, and cooling towers. Recently Hess Machine International has been working with Alternative Environmental Solutions, AES, on a new technique in environmental remediation that uses ozone injection to neutralize MTBE contaminated sites. Let Hess Machine International provide you with the experience and commitment to create installations that will meet or exceed your expectations.

Oxidation Technologies also offers a full line of new and used ozone systems and equipment.
