LN65B Nitrogen generator

‘LN65B-AC’ is the latest Liquid Nitrogen Generator from Noblegen Products.

Utilizing the reliable and efficient PSA technique of separating Nitrogen and Oxygen is used to produce high-quality Nitrogen Gas which is then liquefied using our powerful cooling system.

The liquid nitrogen is stored within a suitable sized vacuum
insulated tank and the product can be dispensed using a 1.5
meter vacuum insulated hose provided.

Other options of dispense methods are available on request.

Available in 2 versions:

Air-cooled version

Water-cooled version

Nitrogen produced at 99% purity using our own PSA nitrogen generator.
Nitrogen injection system used for gas pre-cooling prior to liqueficiation.
Pressure Boost & No Loss systems increasing production efficiency


The Noblegen Cryogenics L65BAC liquid nitrogen generator is your reliable and efficient on-site plug and produces a cryogenic solution.

With a small footprint, low power consumption, and no need for cooling water or a water chiller
makes the LN65B-AC one of the best solutions available on the market.

The integrated cooling fans can operate with air cooling up to +45°c ambient temperatures making them suitable to operate in most parts of the World.

For higher ambient temperatures up to +52°c we recommend the LN60B watercooled system.

Simply connect the power and press start for the machine to automatically produce liquid nitrogen when needed.

An intelligent level sensor system is fitted for you to select the liquid level stop and start using the touch screen controller so you always have enough LN2.

The Pressure ‘BOOST’ system increases liquid nitrogen production with no additional power or cooling water required, coupled with the ‘No Loss’ pressure maintaining system making it the most efficient and intelligent GMbased technology generator available.
