Liquid nitrogen production equipment

Liquid nitrogen production equipmentIntroduction:

Products from Noblegen Cryogenics in the UK

Liquid nitrogen production equipmentIt is a simple plug and play liquid nitrogen solution. 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.

working principle:

The compressed air from the oil-free air compressor first passes through the intake sterilization filter to prevent bacterial growth. Air enters the PSA nitrogen production system to separate nitrogen gas, which is first dried to a dew point of -60 ° C and then filtered using a sterilization filter to comply with the requirements of UK Health Technology Memorandum 02-01.

The liquid nitrogen droplets fall into the vacuum insulated Duval tank for backup, and can also be discharged through a stainless steel conveying hose. The helium compressor is used to cool the cold head, which requires cooling water supply or a closed cycle chiller (optional).

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:

Injecting liquid nitrogen into biological storage tanks in the IVF industry
Cryogenic surgery - removal of skin lesions
NMR (Nuclear Magnetic Resonance) Spectrometer - Keep liquid helium cooled and prevent volatilization
Food Packaging - Fast Cooling Fresh Food
Blood and stem cells
Animal husbandry - Preservation of animals such as cattle, sheep, pigs, etc
Protecting metals during metal processing annealing process
Dropping - Drop liquid nitrogen into bottled beverages to maintain appropriate pressure
aerospace
superconductor
theme park
film production
Remote areas - such as underground, high mountains, islands, ships, etc. that require the use of liquid nitrogen

Some customers use on-site -65 liters per day energy-saving low maintenance type
