The invention relates to an inertisation device (1) for adjusting and maintaining predefinable inertisation levels in a protected area (2) that is to be monitored. Said inertisation device (1) comprises a controllable inert gas arrangement (10, 11) for providing inert gas, a first supply pipe system (20) which is connected to the inert gas arrangement (10, 11) and which can be connected to the protected area (2) in order to guide the inert gas provided by the inert gas arrangement (10, 11), and a control unit (12) which is used to control the inert gas arrangement (10, 11) in such a manner that a predefinable inertisation level is controlled and maintained in the protected area (2). The aim of the invention is to rapidly increase the inertisation level in the protected area (2) to an accessibility level without large structural modifications, for example, installing ventilation flaps in the protected area (2). According to the invention, a valve (31) that can be switched by the control unit (12) is connected to the inert gas arrangement (10, 11) and to the first supply pipe system (20), in order to, according to requirements, guide the exit air to the protected area (2), said exit air provided by the inert gas arrangement (10, 11) by the outlet (Hb) as fresh air. |
