Green nitrogen charging technology is to charge 99.5% high-purity nitrogen into the grain pile, and replace the oxygen in the granary by using special equipment, so that the storage environment can maintain high nitrogen concentration, low oxygen concentration or oxygen free state for a long time,

1. Fixed cold and hot start function, which can reach the standard within a few minutes after start-up;

2. New energy-saving technology reduces energy consumption;

3. The air distributor in the adsorption tower improves the utilization ratio of the molecular sieve, reduces the impact on the molecular sieve bed to the greatest extent, and improves the long-term performance of the use of the molecular sieve;

4. Compound loading ensures the most effective loading effect of molecular sieve;

5. Online detection of nitrogen purity, automatic alarm for unqualified nitrogen;

6. Fixed type and mobile type can be used in different reservoir areas.
