Production Rates

Tonnage Plants are a cost-effective, alternative solution to traditional cylinders or liquid supply. They are designed for applications requiring large amounts of oxygen, or to replace bulk liquid oxygen storage vessels. Plants can be designed for outdoor or covered standard installations.

We supply tonnage plants from 3 to 15 tonnes of oxygen per day.

Many other sizes are available on request.
