摘要

PURPOSE: A movable nitrogen supply device is provided to supply nitrogen in a state over predetermined pressure and selectively supply nitrogen in a state under predetermined pressure. CONSTITUTION: A movable nitrogen supply device comprises a trailer; at least one nitrogen storage tank installed to the trailer; a nitrogen supply part(110) filling the nitrogen storage tank with nitrogen from outside; a gas booster(140) installed to the trailer, to pump the nitrogen stored in the nitrogen storage tank; a high-pressure supply part supplying the nitrogen pumped from the gas in a first predetermined pressure state; and a low-pressure supply part supplying the nitrogen supplied from the gas booster in a second predetermined pressure state lower than the first predetermined pressure.
