<p>PURPOSE: To provide storage equipment capable of storing objects in an atmosphere at low oxygen concentrations at reduced labor and cost for maintenance and equipment cost. CONSTITUTION: A storehouse 1 stores objects 2 and a housing vessel 4 contains an oxygen scavenger 5. There is equipped a circulating channel R so as to start from the inside of the storehouse via the housing vessel and then return to the inside of the storehouse again. The returning flow channel 9 of the circulating channel R is furnished with a mixing valve 41 to mix the air with the gas in the channel R. The gas in the channel R is circulated by a fan 7. Besides, a sensor 16 detects the oxygen concentration of the gas inside the storehouse. When the sensor detects the oxygen concentrations other than a specified value, a control unit 43 drives the fan and also controls the mixing valve according to the value detected by the sensor.</p> |
