Product Overview

Hess Machine Ozone Generators were designed for use in the bottled water industry. These ozone generators produce ozone from dry air with an integrated air dryer, meaning only compressed air, electricity, and cooling water are required for operation. These are the most reliable and robust ozone generators in production today.

The Hess Machine Ozone Generators can be used for any application where ozone from dry air is required. These generators are well built and reliable, allowing them to provide you with many years of operation.

What makes the L-200 different?

The L-200 produces 2 lb/day ozone from 2 horizontal, water cooled ozone tubes.
