Inertization device with nitrogen generator

An inertization device for establishing and maintaining an inertization level in a protective room, the inertization device comprising:

• an inert gas system for providing inert gas, the inert gas system further comprising a nitrogen generator;
• a control unit for controlling the inert gas system to establish and maintain a desired inertization level in the protective room;
• a first supply pipe system providing fluid communication between the inert gas system and the protective room to supply inert gas provided by the inert gas system to the protective room;
• a compressed air source in fluid communication with the nitrogen generator of the inert gas system, wherein the nitrogen generator separates oxygen from the compressed air from the compressed air source to provide a nitrogen-enriched air at a first outlet of the nitrogen generator, the nitrogen-enriched air supplied as the inert gas to the first supply pipe system;
• and
• a bypass pipe system providing fluid communication between the compressed air source and the first supply pipe system, the bypass pipe system having a valve disposed therein, an opening and a closing of the valve controlled by the control unit to selectively permit and militate against a flow of air from the compressed air source to the protective room to at least one of establish and maintain the desired inertization level in the protective room, wherein the bypass pipe system bypasses the nitrogen generator to supply the compressed air provided by the compressed air source as needed to the protective room.

An inertization device for establishing and maintaining an inertization level that can be preset inside a protective room to be monitored, the inertization device comprising:

• a controllable inert gas system for providing inert gas;
• a first supply pipe system connected to the inert gas system and the protective room to provide the inert gas prepared by the inert gas system to the protective room;
• a control unit configured to control the inert gas system such that a specific, presettable inertization level is established and maintained inside the protective room;
• and
• a bypass pipe system connected to the control unit via a shut-off valve, which bypass system is connected on one side to a compressed air source and on an other side to the first supply pipe system to feed the compressed air provided by the compressed air source directly to the protective room as fresh air, and at least one of establish and maintain a specific inertization level inside the protective room.
