‘LN30B-AC’ is the latest ‘air cooled’ 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 LN30B liquid nitrogen generator is your reliable and efficient on-site plug and produces a cryogenic solution with a small footprint, low power consumption, and low cooling water requirement making the LN30B one of the best solutions available on the market.

With cooling water or a chiller supplied the system can operate up to +52°c ambient temperatures making it suitable to operate in most parts of the World.

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

An intelligent level sensor system means you can 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 GM-based technology generator available.
