The 5 Best Nitrogen Regulators [Ranked]
If you’re planning on opening a bar or grill, one thing that’s going to be a must-have item is a nitrogen tank regulator for beverage dispensing (Source).
A nitrogen regulator is a standard pressure control valve that reduces the input pressure from a liquid or gas that is stored in a pressurized tank (Source).
There are hundreds of industrial applications for a gas pressure regulator. They range from air conditioning, air tanks to keg beer distribution.
A nitrogen regulator consists of an output pressure setting, a sensor, and a restrictor all built in one body. Or a regulator may be comprised of a separate controller, pressure sensor, and flow valve (Source).
How They Work
A nitrogen regulator basically reduces the highly pressurized gas or liquid from the tank into a more usable form. Without a nitrogen regulator, you wouldn’t be able to control the flow of the liquid from the pressurized tank and all of it would be released at once as a result of the high pressure.
A nitrogen regulator comes in a variety of styles that are all intended for a specific use in mind. There are primary nitrogen regulators, secondary and also panel models along with a combination nitrogen/Co2 regulator.
For applications that include dispensing beer or wine, a primary regulator is used to reduce the pressurized contents.
Secondary gas regulators are designed to further reduce the pressure from the primary regulator or gas blender to control the flow from the individual beer keg.
The panel regulator is intended for use in the walk-in or large display coolers. A primary CO2 or nitrogen regulator dispenses at between 35-45 PSI and supplies two adjusted secondary regulators that reduce that pressure to 12 and 14 PSI.
