Description


NOBLEGEN LIQUID NITROGEN GENERATORS

Noblegen's  LN2 liquid nitrogen generator plants are a simple plug and produce LN2 solution. An internal PSA nitrogen generator combined with a cryo-cooler, helium compressor and internal dewar all controlled through a colour graphic HMI touch-screen gives a fully auotmated system at the touch of a button.


The LN20AC  Noblegen LN2 liquid nitrogen generator is based on the Gifford-McMahon technique of a cold-head design with the compression and expansion of helium to obtain low temperature cooling. The systems are specifically designed for applications where a certain gas must be liquefied and transferred to an internal storage vessel which can then be dispensed to the application.



PRODUCT FEATURES

Internal oil-free air compressor with autoclave (anti-bacteria) suction filter.

PSA nitrogen gas generator to give -60°c pdp nitrogen gas.

Sterile filter on nitrogen gas line to cryo-cooler.

Reliable low maintenance helium compressor unit

Cryo-head is part of the dewar assemby for efficiency of production.

Liquid nitrogen outlet valve and transfer hose provided.


ADVANTAGES

Produce your own Liquid Nitrogen and eliminate deliveries.

Less waste – cold head keeps the dewar cold and reduces boil off compared to standard dewar.

Efficiency - Once internal dewar filled the system goes into standby, saving power.

Cost - Liquid nitrogen produced around 1/3rd the cost of delivered LN2.

Cleanliness – Closed loop system of nitrogen PSA, cryo-cooler and sterile filter ensures internal dewar is only filled with clean dry nitrogen gas and produces clean / pure liquid nitrogen.


APPLICATIONS

-IVF clinics / hospitals for storage of samples.

NMR spectrometer to keep liquid helium cool and prevent boil off.
