FIELD: cryogenics.
SUBSTANCE: invention relates to the field of cryogenics. Method consists in forming an air stream of atmospheric air, draining it in a rotary adsorption air dryer of low pressure 1, directing the dried air into the air compressor 2 to compress it, separating the compressed air by means of the air separator 3 into two streams, one stream of compressed air is sent to the oxygen consumer, and the other through the nitrogen compressor 4 to the storage nitrogen receiver 5 for the subsequent implementation of pneumatic drive of low-temperature steel reinforcing.
EFFECT: safety of control of the drive of the low-temperature steel reinforcing is increased.
