CO2 Liquid Dewar Adapter Essential for Setting Up a CryoFX Co2 Jet Machine with Dewar Tanks

Co2 Dewar Adapter


For those of you using CryoFX products this short article is a must read, especially if you’re just getting started. Here we will briefly review the CGA 622, CO2 Dewar adapter, an essential component for hooking up your Cryo Special Effects machine to a Dewar tank.


The top of a Dewar tank - a standard CO2 source for CryoFX machines - can be a confusing sight at first. Each outlet and valve serve a particular purpose, so each are important to understand. 


Since each outlet and valve should be clearly labeled, let’s zero in on the most critical one for a CryoFX machine: the liquid outlet. This outlet is the one you’ll use for all CryoFX machines, but it’s important to know that you’ll need a particular CO2 tank adapter to hook up to the outlet properly.


Until 2012, Dewar tanks came standard with liquid CO2 outlets that required a CO2 Dewar adapter called a CGA 320, allowing you to then attach a hose between the outlet and CryoFX machine.


That’s changed. Dewar tanks now come standard with a female outlet, so require a new CO2 tank adapter, the CGA 622, to fit properly to a hose. This  Liquid Dewar adapter is now a necessary part of a secure setup so that your machine functions properly. Here’s a link to the CGA 622 for more information: http://www.cryofx.com/products/co2-dewar-tank-adapter.html


It’s a minor change, but it’s important to make sure that you’re using the correct fitting when dealing with liquids and gases at such high pressures.
