Liquid Nitrogen Generator for laboratories and medical

CRYOGEN GENERATORS

Liquid Nitrogen for laboratories, medical & healthcare, and industrial applications

Liquid Nitrogen finds its applications across a spectrum of industries, from medical, scientific research to metal treatment and dermatology, where ultra-low temperatures are critical. However, handling dewars of liquid Nitrogen can be challenging, with safety risks, logistical hassles, and purity concerns.

The solution? On-site, on-demand liquid Nitrogen production. The CRYOGEN series developed by F-DGSi allows you to generate your own liquid Nitrogen—anytime, anywhere! Just connect it to power, press start, and produce 8 up to 960 liters per day automatically.

The most reliable, efficient & proven technology
for on-site Liquid Nitrogen production

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.

Why choose an Liquid Nitrogen Generator?

Generate liquid Nitrogen on-demand from ambient air using the most reliable, efficient and proven technology available.

Eliminate the inconvenience from delivery delays of liquid Nitrogen dewars and reliance on external liquid Nitrogen suppliers.

Produce 8 up to 960 L/day of liquid Nitrogen (higher capacities available) with our CRYOGEN Series of generators.

Produce liquid Nitrogen with 99% purity (Oxygen < 1%) with the CRYOGEN Liquid Nitrogen generators.

CRYOGEN generators are designed with a robust cabinet, certified built-in dewar, safety valves, and advanced electronics for secure use.

Control the Liquid Nitrogen generator via intelligent, intuitive touch screen to start/ stop, monitor real-time process, set all parameters and schedule maintenance.
Use the insulated cryogenic hose to easily dispense the liquid Nitrogen once the built-in dewar is filled.

CRYOGEN generators require minimal servicing and ensure maximum uptime of the liquid Nitrogen production.

Monitor and control CRYOGEN generators via USB cable for a laptop connected to the internet or via a direct internet connection.

On-site generation of liquid Nitrogen using a generator is cost-effective and delivers a fast return on investment.

CRYOGEN generator automatically switches to economy mode when not in use, reducing energy consumption, while sustainable on-site production eliminates the need for truck deliveries.

Built-in Oxygen sensor alerts the staff when oxygen levels become critical.

Liquid Nitrogen Generators
in diverse fields

Cryopreservation

Process that preserves organs, tissues, human and animal semen, fertilized or any other biological constructs by cooling the samples to the boiling point of liquid nitrogen.

Cryotherapy

Cryotherapy, known as cold therapy, is used in medical therapy to treat a variety of tissue lesions or skin abnormalities (cryosurgery). It is also in an effort to relieve muscle pain, sprains and swelling after soft tissue damage (especially among athletes).

Gastronomy

Liquid nitrogen in the gastronomy is often used in modern cuisine for the production of frozen foams and ice cream. After freezing food, nitrogen boils away creating a thick nitrogen fog. Liquid nitrogen is also appreciated by chefs for molecular gastronomy and the preservation of food products.

NMR

The Nuclear Magnetic Resonance Spectroscopy, analytical technique, is used to analyse the physical and chemical composition of materials. Liquid helium is required to cool down the superconducting magnet of NMR and liquid nitrogen is used to absorb heat from outside the magnet and reduce the helium boil off rate.

In-Vitro Fertilization

In-Vitro fertilization is an assisted reproduction technique. The use of liquid nitrogen allows for medical hibernation of embryos, sperm and oocytes (eggs). This biological sleep in liquid nitrogen can last for years.

GC-2D

Two-Dimensional Gas Chromatography (GC-2D) is a technique for analyzing complex samples which involves the use of several columns used in series. The two columns are separated by a cryogenic modulator consisting of a hot air jet and a cold air jet (cooled with liquid nitrogen). The liquid nitrogen traps the eluting molecules of the first dimension and the hot air jet sends them to the second dimension column. If your application requires extremely volatile modulation, the liquid nitrogen cooled modulator is recommended.

Cells

The purpose of using liquid nitrogen is to preserve cells for the long term but also to apply a source of cold to tumor lesions (cryosurgery). Liquid nitrogen can freeze several types of cells: graft while waiting for transplant, hematopoietic stem cells (bone marrow) while awaiting reinjection, blood, lymphocytes and platelets.

Metal treatment

Metals like steel, iron, copper and aluminum are often heat treated to improve their physical properties. The metal is exposed to heat and then to cooling. This cryogenic hardening is characterized by the use of liquid nitrogen to freeze metal.

Dermatology

The use of liquid nitrogen in dermatology destroys certain skin lesions. Heat shock causes crystallization of the water contained in the cells. The freezing and heating phases constitute a freeze-thaw cycle. Many benign lesions can be treated with liquid nitrogen: acne, scars, warts, skin growths, skin cancer.
