Liquid Nitrogen Generator Price

CANGAS Systems Company Limited | Updated: Apr 29, 2016

Did you ever think you could make liquid nitrogen in your own garage? This is an industrial process so how can an individual do this? Still doubt me? Intrigued? Read on.

As a lover of science I tried to think of a challenging project that was out of the ordinary. After going through the internet web and Youtube I realized that no one had made liquid nitrogen in his home. Yes, I did see some videos where some would use a Stirling Cooler from a cryorefrigerator and use this to condense nitrogen on the exterior of the cold-head. While one is making liquified gas, this is done using a prefabricated machine. I wanted to make the machine that liquefies the gas. Furthermore, a cryocooler has a very low production rate. You will only get about 500 - 1000ml per day. On the following pages I will walk you through the basics of how to build your own liquid nitrogen generator.  Using easily obtained materials you can liquefy nitrogen or air. The unit cools  to -320F in under 50 minutes. The production rate is about 350 cc/hr.

You are welcome to contact me, we can go over theory, thermodynamics and more detail on where to get components and how to build this. Presentation is available. This Instructable serves as a general introduction to how this baby is put together. In the presentation, it mentions the PSA we made for making the pure N2 from the air for the generator. If you're ready for 320 degrees below zero we can begin..

Also a rang of products could fully cover your gas need. See the one below.

A low‚Äźpressure laboratory liquefier having a capacity of 45 to 50 liters per hour is described. A combination of old and new features makes possible continuous operation without an attendant. Impurities such as water, carbon dioxide, and oil are eliminated automatically by reversing exchangers. The liquid nitrogen product flows directly from the rectifier to a large external storage vessel. The net power requirement is approximately 50 kilowatts.
