On-Demand, Safe and Convenient Liquid Nitrogen Generation

Handling dewars of liquid Nitrogen can be challenging, with safety risks, logistical issues, and purity concerns. The solution? On-site, on-demand liquid Nitrogen production. The CRYOGEN series from F-DGSi allows you to generate your own liquid Nitrogen—anytime, anywhere. Just connect it to a power supply, press start, and produce 8 up to 480 liters per day automatically.

How to generate Liquid Nitrogen with CRYOGEN?

The liquid Nitrogen generation process of the CRYOGEN series starts with producing Nitrogen gas from ambient air, cooling and liquefaction, and ends with dispensing liquid Nitrogen directly from a built-in dewar.

At the core of the CRYOGEN Liquid Nitrogen generator lies the Gifford-McMahon technique, which uses a cold-head design to compress and expand Helium, achieving low temperature cooling of the gaseous Nitrogen. A Cryo-Refrigerator mounted on the built-in dewar converts the generated gaseous Nitrogen into liquid Nitrogen at –196°C (-321°F). The cooling of the CRYOGEN is possible either by Air or Water depending on your cryogenic requirements.

The liquefied Nitrogen drops down into a built-in certified dewar and can be dispensed easily through an insulated cryogenic hose. A dedicated sensor monitors the produced liquid Nitrogen levels, and the touch screen control allows real-time process management and liquid level monitoring. It also gives access to the service menu to check the running hours, schedule maintenance or review the logged events. Remote operation is possible via USB or internet connectivity.

The CRYOGEN system delivers from 8 L/day up to 480 L/day to meet the needs of most applications requiring liquid Nitrogen. Make your own liquid Nitrogen, anywhere, anytime!
