Nitrogen liquefaction system

Nitrogen liquefaction systemIntroduction:

Products from Noblegen Cryogenics in the UK

The compact laboratory liquid nitrogen generation device is a simple plug and play solution for liquid nitrogen. Based on the Gifford McMahon cold head process, combined with helium compression and expansion to achieve low-temperature cooling. Built in oil-free air compressor, PSA pressure swing adsorption nitrogen generator, refrigeration unit, helium compressor, and Duwa tank, controlled by a color touch screen, with one click for fully automatic operation.

Nitrogen liquefaction systemProduct Features:

Compact and silent design

Fully automatic operation with energy-saving module

Built in oil-free air compressor and sterilization suction filter

PSA nitrogen generator provides nitrogen gas with a dew point pressure of -60 ° C

Install a sterilization filter before the nitrogen pipeline to the refrigeration unit

Extremely reliable low maintenance helium compressor unit

Cold head integrated into the Duwa tank provides high efficiency

Including liquid nitrogen outlet valve and conversion hose

Advantages:

Produce liquid nitrogen independently and terminate transportation.

Less waste - The cold head can maintain a low temperature in the Duwa tank and reduce the vaporization of traditional Duwa tanks.

Efficiency - Once the built-in Duwa tank is full, the system automatically goes on standby, reducing energy consumption.

Cost - The production cost of liquid nitrogen is only one-third of the transportation cost of liquid nitrogen.

The clean closed PSA nitrogen cycle system, refrigeration unit, and sterilization filter ensure that only clean and dry nitrogen is injected into the Dewar tank, and produce clean and pure liquid nitrogen.

Application areas:

In vitro fertilization (IVF) clinics/hospitals store samples

Maintain liquid helium cooling and prevent volatilization in NMR spectrometer

Blood and stem cells

Metal processing (rapid cooling)

scientific research

University laboratory

aerospace

superconductor

Bottled water production

theme park

film production

Remote areas - such as underground, high mountains, islands, ships, etc. that require the use of liquid nitrogen

Liquid nitrogen, liquid nitrogen gas. It is inert, colorless, odorless, non corrosive, non flammable, and has an extremely low temperature. Nitrogen constitutes the majority of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inert and does not support combustion. Excessive heat absorption during vaporization can cause frostbite. Nitrogen accounts for 78% of the air.

Under normal pressure, the temperature of liquid nitrogen is -196 ℃; 1 cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen at 21 ° C. Liquid nitrogen is a colorless, odorless, low-temperature liquid and gas under high pressure. Liquid nitrogen (often written as LN2) is a liquid form of nitrogen gas formed at low temperatures. The boiling point of nitrogen is -196 ° C, and below this temperature at normal atmospheric pressure, liquid nitrogen will form; If pressurized, liquid nitrogen can be obtained at higher temperatures.

In industry, liquid nitrogen is obtained by fractional distillation of air. First, purify the air and then liquefy it in a pressurized and cooled environment, separated by the different boiling points of each component in the air.
