20L per day laboratory liquid nitrogen plant

20 liters/day laboratory nitrogen gas generator

20 liters/day laboratory nitrogen gas generator is an air-cooled liquid nitrogen generator from Noblegen Cryogenics. By using reliable and efficient PSA technology to separate nitrogen and oxygen, the produced high-quality nitrogen gas is liquefied by a powerful cooling system.

Liquid nitrogen is stored in a vacuum adiabatic tank of the corresponding size, using a self-contained 1.5 m vacuum adiabatic tube to distribute liquid nitrogen. You can also choose other allocation methods.

Laboratory nitrogen gas generator features

4.Liquid nitrogen purity 99%
5.Booster systems increase production (LN30 and above)
6.Zero loss pressure system (LN30 and above)
7.Built-in bulk liquid nitrogen storage dewar
8.All cryogenic parts are vacuum - insulated
9.Color touch screen control
10.Small area
11.Low noise

Introduction

20 liters/day laboratory nitrogen gas generator is your reliable and efficient plug and play liquid nitrogen solution. a small area, low power consumption and no need for cooling water or chillers make LN20AC one of the better solutions in the market.

Integrated cooling fans can operate at 32℃ ambient temperature, and external long distance fans can operate at up to 45℃, making them suitable for operation in most parts of the world. LN20 water-cooled type can operate at ambient temperatures up to 52℃. Just connect the power supply and press the start key to produce liquid nitrogen automatically when needed. Intelligent liquid level induction system means you can select stop and start liquid level through touch screen, so you always have enough liquid nitrogen.

20 liters/day laboratory nitrogen gas generator Technical Specifications

When the following problems occur in the process of using the laboratory nitrogen gas generator device, you can repair it yourself:

1. When the liquid nitrogen pressure does not reach the set value, the flow meter should be observed first. If the flow rate display is larger than usual, it can basically be concluded that there is a gas leakage problem in the entire system.
Solution: Turn off the power first, remove the gas path, the liquid nitrogen outlet needs to be sealed with a sealing nut, and then turn on the power of the liquid nitrogen generator to see if the pressure can reach the set value and whether the flow rate display can reach "000" If the flow rate display can return to zero, it means that there is no air leakage in the instrument itself, then please check the pipeline after the gas outlet and the air-using equipment for air leakage. If the flow rate display cannot return to zero, there is a leak point. Please use soap to check the drying pipe for leaks.

2. There is a noise during operation.
Solution: Use a wrench to properly adjust the tightness of the nut on the instrument, not too tight; if it does not work, you need to disassemble the instrument shell and clean the inside (the main reason is that there are impurities inside). of.

3. During the running process, the meter shows that the digital large pressure cannot reach the set value.
Solution: This is caused by air leakage, and it is necessary to carry out a comprehensive leak detection of the gas circuit, especially the drying room and the battery.
