FIELD: process engineering.
SUBSTANCE: invention relates to inerting device 1 to be installed to maintain preset inerting level in protected premises 2. Proposed inerting device 1 incorporates inert gas controlled system 10, 11 to feed inert gas, first feed pipeline system 20 connected to inert gas system 10, 11 and may be connected with protected premises 2 to feed inert gas prepared by system 10, 11 into premises 2, and control unit 12 designed to control inert gas system 10, 11 to maintain preset inerting level in said premises. To rapidly up the inerting level in protected premises 2 to habitability without, say, building in vent valves, this invention proposes to use valve 31 to be connected to control unit 12, inert gas system 10, 11 and first feed pipeline system 20 to feed air prepared by system 10, 11 as a fresh air into protected premises 2 via outlet 11b.
EFFECT: maintaining preset inerting level.
