Liquid Nitrogen Generator for laboratories and medical

CRYOGEN GENERATORS

Liquid Nitrogen for laboratories and medical

The CRYOGEN system is a liquid nitrogen generator which allows you to produce, on demand, your own cryogenic. Liquid nitrogen is a refrigerated liquefied gas with a boiling point of -196°C (-321°F). It is used for many applications where very low temperatures or large temperature reduction is required. Eliminate the cost of buying liquid nitrogen and the hassle of waiting for deliveries.

The most advanced technology for
on site Liquid Nitrogen production

Our CRYOGEN units produce high quality liquid nitrogen (LN2) on site from ambient air. Our own PSA technology separates N2 from O2. The nitrogen gas produced is then cooled until it liquefies. It can then be distilled. The liquid nitrogen is transported in a container called a dewar. This vessel is fully insulated. The system can deliver from 10 L/day up to 60 L/day to meet the needs of most applications requiring LN2. Simply connect the unit to a power supply and the system is ready to deliver liquid nitrogen cooled to -196°C (-321°F) at the touch of a button.

F-DGSi provides you with reliable, fully automated, all-in-one technology including: our PSA technology, a liquefaction system with air or water cooling, and easy-to-handle external dispensing. The generator is controlled using an HMI touch screen to display the process in real time, the dewar liquid level and the nitrogen production generated.

8 Good reasons to choose
F-DGSi Liquid Nitrogen Generator

Routinely, CryoGen units supply LN2 at 99% purity (02 < 1%) checked automatically by an O2 sensor connected to an alarm.

CryoGen units are remotely controllable via USB cable for a laptop connected to the internet or via a direct internet connection if available as an option. It allows us or users to check all the parameters, archive the log book and get information by email directly.

As soon as the internal tanks is full, the users just have to use a valve connected to a hose to fill external dewars. The valve and hose could be inside the cabinet or outside as an option.

All the parameters are accessible using an intelligent and intuitive touch screen. Start/stop the unit, check LN2 level in the internal tank, check running hours and service hours, schedule the production during the week…And a log book is available to check all the events.

Having such units on board allow users to get access to LN2 when they want and use what they really need for their applications.

When the system is not producing, we use our Energy Saving Mode technology to put the system in economy mode to save consumption, save running hours and extend preventive maintenance.

Low and High LN2 levels in the internal tank are set up by the user and automatically controlled.

Getting a CryoGen unit allows you to be independent from gas suppliers, from truck deliveries and be more secure as you can install the unit much closer to your needs.

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.
