The nitrogen making machine refers to a equipment that uses air as raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen.

Nitrogen making machine is a nitrogen equipment designed and manufactured according to pressure swing adsorption technology. High purity nitrogen is produced by using high quality carbon molecular sieve (CMS) as adsorbent and pressure swing adsorption (PSA) principle at normal temperature to separate air. Two adsorption towers are usually used in parallel, and the pneumatic valve controlled by a PLC (programmable controller) runs automatically, alternately performing pressure adsorption and decompression regeneration to complete the separation of nitrogen and oxygen, and obtain the required high purity nitrogen.

Therefore, compressed air is an essential step in the nitrogen production mechanism, so the air compressor is a good choice in the working process of the nitrogen production machine.

The air pressure source required by the nitrogen production mechanism nitrogen equipment must be a dry and clean compressed air source with a pressure above 0.7Mpa and below 0.8Mpa - because the molecular sieve of the nitrogen production mechanism nitrogen equipment has a good adsorption effect between this pressure.

Sometimes considering the price of oil-free air compressors is a little high, it is also necessary to choose micro-oil air compressors as far as possible, but the purification part behind the need to add oil remover to ensure the relative cleanliness of compressed air. If it is used in the food industry food nitrogen machine or recommended to choose oil-free air compressor.

So a nitrogen production mechanism nitrogen equipment in the end to choose how much air compressor? Here we have a calculation method, the purity of 99.9% of the nitrogen mechanism nitrogen equipment requires the amount of compressed air is 5 times the nitrogen production of the nitrogen mechanism nitrogen equipment, such as a 3 cubic nitrogen mechanism nitrogen equipment of compressed air per minute is not less than 0.35m3/min. If the purity of 99.99% of the nitrogen production mechanism nitrogen equipment requires the amount of compressed air is 7 times the nitrogen production mechanism nitrogen equipment, such as a 5 cubic nitrogen production mechanism nitrogen equipment of compressed air per minute is not less than 0.65m3/min. Hopefully, this method will make it easy for you and your business to choose the air compressor you need for your nitrogen equipment.
