What is CryoDoser?

The CryoDoser is the premier liquid nitrogen (LN2) dosing system utilizing advanced cryogenic technology and PLC programming.
Three sensors detecting line speed, timing, and bottle presence allow the system to detect all lines speeds, including high speeds, to dispense a precise dose of LN2 into every container every time.
The LN2 gasifies and is either trapped in the container to add rigidity or escapes with oxygen to inert the headspace.


How it Works

LN2 is supplied to the CryoDoser by a standard 10ft (3mt) vacuum insulated CryotechFlex hose (various lengths available) and flows into the dosing head.
A 24vdc PNP sensor detects the speed of the line (encoder compatible for higher speeds); a second 24vdc PNP sensor detects the presence of a container.
When a container is detected, the dosing head opens and dispenses an exact amount of pure LN2.


Using LN2 in Your Production Lines


Our CryoDoser systems are easy to operate and can be integrated into new or existing lines.
System integration can be done by Cryogas to supply LN2 from bulk tank or liquid cylinder.
Our design versatility allow to use both rigid and flexible vacuum insulated piping system to transfer the liquid nitrogen from large bulk storage tanks or portable dewars to the LN2 systems in customer production plant.
Saves MONEY! Our piping system is using advanced static vacuum insulation technology for cryogenic transfer, thus helping to reduce liquid nitrogen consumption cost by 50% within the food and beverage industry.
