Ldh-Gas Laboratory Compact Skid 20L/Hr Automatic Start-Stop Liquid Nitrogen Generator

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.

Industrial use

In industrial production, liquid nitrogen obtained by compressed liquid air fractionation can be used as deep refrigerant. Because of its chemical inertia, it can directly contact with biological tissue and freeze immediately without destroying biological activity, so it can be used as deep refrigerant

(1) Rapidly freezing and transporting food, or making ice products;

(2) Research on low temperature physics;

(3) Demonstrate the low temperature state in science education. At room temperature, a soft object soaked in liquid nitrogen will be as brittle as glass;

(4) Provides the temperature required for high temperature superconductors to show superconductivity.

(5) It can be used as refrigerant to quickly freeze biological tissue to prevent tissue damage.

(6) It is used for industrial nitrogenous fertilizer.

(7) For chemical detection.

Liquid nitrogen is a liquid with a low temperature of - 196 ºC and is obtained from nitrogen which occupies more than 70% of the air. Inert, colorless, non-toxic, volatile, very wide range of use. Liquid nitrogen is easy to volatilize at low temperature, so it is generally stored in a special container liquid nitrogen tank.

According to the use of liquid nitrogen purity classification, often divided into food grade liquid nitrogen, industrial grade liquid nitrogen. The purity of food grade liquid nitrogen is high, because considering the safety of human consumption, the purity reaches 5 9, that is 99.999%. The purity of industrial grade liquid nitrogen is not as high as that of food grade liquid nitrogen.

In the process of using liquid nitrogen, people often think that the safety is not good, but because of the low temperature of liquid nitrogen, it will gasify immediately when it meets air, so the safety is still guaranteed. Just pay a little attention to safety, and there should be safety awareness in any case.

Performance requirements

Liquid nitrogen production: 1-50L / h
Storage capacity: 120L, environment: 10 ºC - 38 ºC
Control: PLC touch screen, power: 200v-400v, 3P, 50 / 60Hz

Applications of Nitrogen
Nitrogen is very important gas for various industries including chemical where it is used for making fertilizers, nitric acid, nylon, dyes, and explosives. Being known for its inerting properties, nitrogen is ideal for preservation of food and making of diodes and transistors. The non-reactive gas is used on a large scale in annealing stainless steel and various other products used in the generation of steel. Annealing is a heat treatment that making it easier to work on steel. It is used for freezing foods and helping them to maintain texture, flavor, color and moisture. Numerous other applications include:

Storage of sperm, eggs and other cellular materials
Beverage industry (coca cola ,juice bottling )
Glass industry
Freezing seafood
Nitrogen refinery
Tunnel freezin

Liquid nitrogen is a colorless, odorless, non-flammable, non-corrosive and extremely cold element that finds a lot of applications including research and development.

Liquid Nitrogen Liquefaction :

Liquid Nitrogen Plant (LNP) draws out Nitrogen gas from the atmospheric air and then liquefies it with the help of Cryo cooler.

There are two methods through which Nitrogen can be liquefied:

Pressure Swing Adsorption with Cryo generator.
Distillation of liquid air.
Working principle of Liquid Nitrogen Plant

In a Liquid Nitrogen plant, the atmospheric air is first compressed to 7 bar pressure into compressor. This high temperature compressed air is then cooled in the external refrigeration system. Then, the cooled compressed air is passed through moisture separator to trap the moisture from the air. This dry compressed air is then passed through a bed of carbon molecular sieves where Nitrogen and Oxygen are separated from the air. Separated Nitrogen is then allowed to get through Cryo cooler which cools the gaseous Nitrogen to a liquid state at the boiling point of Nitrogen (77.2 Kelvin). Finally, the Liquid Nitrogen gets collected in Dewar's vessel where it gets stored for several industrial purposes.

Uses of Liquid Nitrogen
Liquid Nitrogen is used in many applications because of its very low temperature and low reactivity. Some of the common applications are:

It is used in cryo therapy to remove skin abnormalities
Serves as a source of an extremely dry gas
Freezing and transporting of food products
Cooling of superconductors like vacuum pumps, and other equipment
Cryo preservation of blood
Cryo preservation of biological samples like eggs, sperms, and animal genetic samples.
Preserving of animal's semen
Branding of cattle
Cryosurgery (removing dead cells from the brain)
Quick freezing of water or pipes to let workers work on them when valves are not available.
Protects materials from oxidization.
The shielding of materials from oxygen exposure.
Other applications that include creating Nitrogen fog, making ice-cream, flash-freezing, flowering that shatters when tapped onto a hard surface.
