FIELD: electricity.
SUBSTANCE: system contains the shelter restricting emissions spread, at least one outlet channel for collection of the above gas flow and suction devices for removing the above gas flow from electrolysis unit. The shelter contains detachable covers and optionally at least one door providing the access inside the shelter, at least one tube for injection of compressed air inside outlet channel so that the flow of the above gas can be increased. Compressed air supply source is brought into action at the specified pressure Po so that the specified flow Ro can be provided.
EFFECT: providing the possibility of suction power redistribution for reduction of suction power on one certain electrolysis unit at maintaining the suction power for all electrolysis units of the shop.
