What is a Primary Regulator?

Kegging is a fun way to dispense beer. If you are planning to build a small kegerator or want to dispense beer from your homemade bar, then it is crucial that you know about their components. One of the most critical parts to get your brew from the keg to a glass is a regulator. It functions by dispensing the gas tank at a specified pressure that you need. As the pressure in a Carbon dioxide or nitrogen tank is very high, the regulator allows you to control the amount of pressure that you think is appropriate in dispensing your homebrew.

There are different types of regulators that you can use in building your kegerator, and one of them is the primary regulator. The primary regulator is a standard regulator that all homebrewers should use. It is used to regulate Carbon dioxide or nitrogen. It has at least one gauge that features the pressure output of between 0 to 60 pounds or PSI. (more info below)

The primary regulator is connected to the gas tank directly. They also come with a safety relief valve and shut-off valve regardless of the brand or model. These shut-off valves are necessary to immediately stop the gas flow before it gets dangerously high. Having too much pressure within the regulator may cause the regulator to burst, thus the need for safety features.

Primary regulators are for one keg; however, you can still use it to dispense two kegs by using a 2-product primary regulator. This type of primary regulator includes two hose nipples so that two kegs can dispense beer using one gas source. You can also use triple gauge options to three kegs. However, if you plan on connecting more multiple kegs with one source, then using a secondary regulator is your best option.

If you aim to build an average draft beer system, then go ahead and install a primary regulator. Happy kegging!
