High purity small liquid nitrogen plant

WORKING PRINCIPLE

Laboratory in liquid nitrogen machine is based on the principle of pressure swing adsorption, using high-quality carbon molecules as adsorbents to produce nitrogen from the air under a certain pressure. The purified and dried compressed air is subjected to pressure adsorption and decompression desorption in the adsorber. Due to the kinetic effect, the diffusion rate of oxygen in the pores of the carbon molecular sieve is much greater than that of nitrogen. When the adsorption does not reach equilibrium, the nitrogen is enriched in the gas phase to form the finished nitrogen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to realize regeneration. Generally, two adsorption towers are set up in the system, one tower absorbs nitrogen and the other tower desorption and regeneration. The two towers are automatically controlled by the PLC program to make the two towers work alternately. 

SPECIFICATION CLASSIFICATION

PRODUCTS ADVANTAGE

1.No need to buy LN2. All you need is a power supply. Switch to ECO mode, which optimizes operation based on the LN2 level in the internal dewar, reducing power consumption. This helps provide reliable cooling, even in locations with erratic power supplies or remote islands.

2. No need to monitor the liquid nitrogen level, our Liquid Nitrogen Plant provide a steady supply of liquid nitrogen. This removes the burden of monitoring LN2 on a daily basis.

3. Stable cooling of important samples is possible even in the event of a disaster. In the event of a power outage, the production of LN2 can be continued using the backup power supply. This provides stable cooling for critical biological samples at research institutions.

4. Eliminating the inconvenience, improving safety The management of safe transport of LN2 inside research facilities requires a lot of work. With our liquid nitrogen generators, you will no longer have the inconvenience of managing the inventory and delivery of liquid nitrogen bottles, while also increasing the level of safety.
