Product Description

 

What is liquid Nitrogen
Liquid Nitrogen Generator is the machine can produce liquid nitrogen or oxygen machine .
The liquid can be into gas with low temp.

LDH liquid Nitrogen Generator has below features 

1. Capacity from 3L/h to 50L/h. Meet all your requirements.
2. Low power consumption.
3. Automatic operate. One key start.
4. Small floor space.
5. Durable. Can work 24 hours per day.
6. One station of liquid nitrogen generator manufacture. ( we supply liquid nitrogen generator, vacuum tube and liquid nitrogen dewar.

LDH series liquid nitrogen equipment is based on the pressure swing adsorption principle, using high-quality carbon molecular sieve as adsorbent, under a certain pressure, from the air to produce nitrogen. After purifying and drying compressed air, pressure adsorption and decompression desorption are carried out in the absorber. Due to the kinetic effect, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much higher than that of nitrogen. When the adsorption is not in equilibrium, nitrogen is enriched in the gas phase to form the finished nitrogen. Then decompression to atmospheric pressure, adsorbent adsorption of oxygen and other impurities, to achieve regeneration. Generally, two adsorption towers are set up in the system. One tower absorbs nitrogen and the other tower is desorption and regeneration. Automatic control by PLC program makes the two towers work alternately. The finished nitrogen is then passed through the refrigerator to produce liquid nitrogen.

Technical features:
1. Adopt diversified environmental protection refrigerating medium with independent intellectual property rights2. The cold box adopts special secondary foaming technology to achieve good thermal insulation effect3. The refrigeration system adopts internationally famous compressor, which is safe and durable, and the spare parts are conventional4. Compared with the traditional Stirling liquid nitrogen unit, it has the following advantages: low cost, no regular maintenance, high reliability and long service cycle.

LDH Liquid nitrogen generator drawing 

Liquid nitrogen generator Working principle:

Mixed-refrigerant Joule-Thomson (MRJT) refrigerator at low temperature ranges driven by
single compressor with precooling is applied to liquefy nitrogen (-180ºC) for Nitrogen Liquefier
from TIPC, CAS. MRJT, a Joule-Thomson cycle based on reoccupation and multicomponent
mixed-refrigerants through optimizing various refrigerants with different boiling points
with a good match along with their respective efficient refrigeration temperature ranges,
is an efficient refrigerator for the temperature range from -40 to -196ºC.
The feature of this product is as following: the available mature commercial compressors
and heat exchanges, high liquefaction efficiency, high reliability, no maintenance and long life.

LDH LN2 Generatior applications 

Mainly in universities, scientific research laboratories, the advantage is that the independent
production of liquid nitrogen, with the production, no need to go far to purchase liquid nitrogen dew-pot, improve the convenience of use.

Output is customized from 1 litre to 50 liters per hour. Depending on the user's usage.

Convenient compact, easy to move, low energy consumption.

During the use of the equipment, it can realize one-button startup and one-button shutdown with a high degree of automation. Generally, it can be achieved after simple training and does not require too much professional knowledge and skills.
