Inertisation unit for continuous ovens

Münstermann designs, develops and produces the so-called inert gas dryers and ovens very successfully.

Why inertisation?

When the concentration of steam and dust cannot normally or has to be reduced to a safe level, the atmosphere in the unit is set by adding an inert gas such as nitrogen or carbon dioxide in such a quantity that a non-critical and maximum permissible concentration is reached.

In some cases it is also important that the concentration of oxygen is reduced because it may have a direct negative effect on the production process or the quality of the product produced.

Exemplary inertisation unit

The illustration shows a part of an exemplary design of an inertisation unit, which regulates the supply of nitrogen to an oven with multiple zones. The oxygen content in every zone can be continuously adjusted from 1 to 21 % by means of N2-control valves. With the introduction of forming gas (5 % hydrogen in nitrogen) the oxygen concentration levels can be reduced to 0.3.
