Suzhou nitrogen machine: the main classification of nitrogen machine
  Deep-cooled nitrogen production: Deep-cooled nitrogen production is a traditional nitrogen production method that has been used for decades. It uses air as raw material, compresses, purifies, and then uses heat exchange to liquefy the air into liquid air.
  Nitrogen production by molecular sieve: using air as raw material, carbon molecular sieve as adsorbent, using the principle of variable pressure adsorption, using the carbon molecular sieve selective adsorption of oxygen and nitrogen to make nitrogen and oxygen separation method, generally known as PSA nitrogen production. This method is a new nitrogen production technology that developed rapidly in the 1970s.
Nitrogen production by membrane air separation: using air as raw material, under certain pressure conditions, oxygen and nitrogen and other gases with different properties in the membrane with different permeation rates to separate oxygen and nitrogen. Compared with other nitrogen production equipment, it has the advantages of simpler structure, smaller size, no switching valve, less maintenance, faster gas production (≤ 3 minutes), convenient capacity increase, it is especially suitable for nitrogen purity ≤ 98% of the small and medium-sized nitrogen users, with the best function price ratio. When the nitrogen purity is above 98%, it is more than 15% more expensive than a PSA nitrogen generator of the same size.
  The above is about Suzhou nitrogen machine: the main classification of nitrogen machine, the content is for reference only!
