Liquid Nitrogen Generators in India


Liquid nitrogen generators are industrial systems which are used for production of nitrogen for use in industrial and medical applications. Our company is known for fabricating and manufacturing nitrogen gas plant using high quality raw materials. Manufacturing and fabricating is done in a technical collaboration ING. L. & A. Boschi, which is an acclaimed Italian company for manufacturing industrial nitrogen generators using cutting-edge cryogenic technology. The proprietary Boschi technology is used in the fabricating of the machinery. Boschi technology provides you with the cross row trays, cryogenic materials and high purity heat exchangers due to which we get regular flow and high purity of liquid nitrogen. We manufacturer all kinds of plant machinery including nitrogen manufacturing generators, psa nitrogen generator manufacturers setup cost and small nitrogen gas generator.

Situated in New Delhi, our liquid nitrogen generator factory is reputed for fabricating nitrogen production plants with precision and high skills. Our factory is also equipped with R & D center, which is engaged in innovating nitrogen generating machinery as per the market requirements and trends. We invest a great deal of our resources in research to produce nitrogen plant machinery which delivers top-class performance and is durable. Our nitrogen generator manufacturers setup cost is competitive in the market.  Being the leading nitrogen plant manufacturer, we offer nitrogen generators, liquid nitrogen generators manufacturers, nitrogen gas generator, nitrogen generation and filling plants in different sizes and capacities ranging from 20m3/liter to 200m3/liter. Our nitrogen machinery is ISO 9001:2008 and CE certified.

How Liquid Nitrogen Generators Work?

Compression of atmospheric air: 

Air is compressed at a very low pressure of 5-7 bar (Kg/cm2) using latest air compressors pre-cooling. It is the 2nd stage of the process and uses a low pressure refrigerant for pre-cooling the warm processed air incoming from air compressor to temperatures around 5 to 10 degrees Celsius before it reaches the purifier. 

Purification of air by purifier: 

Air enters purifier made up of twin molecular sieve driers working alternately. The sieves separate carbon dioxide and other impurities from the process air before it reaches the air separation unit. 

Cooling of air by expander: Air is cooled below sub zero temperatures for ensuring liquefaction and cryogenic refrigeration. A highly efficient expander is used to cool air below -165 to -170 Celsius.

Separation of liquid air into nitrogen and nitrogen: After air is cleaned of impurities, it enters the fin type heat exchanger where the air is cooled below sub zero temperatures by air expansion process in the expander. Air becomes liquefied when it enters air separation column and gets separated into nitrogen and nitrogen by rectification. Nitrogen generated in this way has purity up to 99.7% 

Nitrogen storage in tanks: After nitrogen is separated in the distillation column it is stored in nitrogen tanks. Mostly, it is stored as liquid nitrogen in cryogenic nitrogen storage.
