Skid-mounted LN2 Generator​

The MINNUO medium-sized nitrogen generator is a skid-mounted liquid nitrogen solution. The MINNUO nitrogen skid package contains everything you need to generate your own liquid nitrogen on-site. Why buy liquid nitrogen when you can produce and store your own? Our nitrogen generation offers the sustainable and cost-efficient alternative to gas deliveries.

Working principle

Compressed air passes through the screw air compressor, after cold and dry suction and filtration, it enters the PSA nitrogen generator, and after passing through the sterile filter, it generates sterile nitrogen with a dew point of -60℃. After the sterile nitrogen enters the refrigerator (the refrigerator is cooled down by the chiller), it is liquefied into liquid nitrogen.


  • Liquid nitrogen output: 10L/h-100L/h (240L/day-2400L/day)
  • One key start/stop: One key to control the whole system start/stop
  • Timer start/stop: you can freely set the start/stop time every day
  • Liquid level start/stop: If equipped with liquid nitrogen tank with liquid level meter, it can start/stop according to liquid level control and display liquid level

Remote monitoring: MCGS remote monitoring, can remotely download historical operation records, online program upgrade, convenient remote maintenance

How to Choose Skid-mounted LN2 Generator​?

  1.  Choose the right nitrogen concentration

    Incorrectly selected concentration can become a factor in a significant increase in the price by several times. A difference of 0.05% in concentration can double the cost of the system.

  2.  Calculate station performance

    Considering all consumer parameters, calculate the total amount of nitrogen consumed. Pay attention to the units of measurement, the flow must be normalized, m³/h at a pressure of 1 bar and a temperature of 20°C.

  3.  Consider the operating conditions

    All parameters of the station are specified under standard operating conditions of 20°C, The temperature rises above 38℃ will affect the air compressor, so be sure to keep the use of the site ventilation heat

  4.  Choose a compressor with a margin of 10%

    For the correct operation of the system, many factors must be taken into account: the nature of consumption, the number of peak loads, additional losses of compressed air, the volume of receivers, and much more.

  5. How Much Cost?

    Start a small 20m³ PSA N2 generator price is $12000. We promise a good price with top quality.
