Carbon Dioxide + Nitrogen = Beer Gas
There are only two types of gas that are used in beverage systems – carbon dioxide (CO2) and nitrogen (N2). Some might argue that there is a third called beer gas – a blend of carbon dioxide and nitrogen.
The most used gas – carbon dioxide. From carbonating soda to sparkling water to pushing beer for draught systems, CO2 does it all and it’s always used in beer systems when serving draught beer
All beer is carbonated. CO2 provides two purposes:
- it helps push the beer out of the keg and,
- in the headspace of the keg or the serving tank, it helps maintain proper carbonation levels.
Just keep in mind that carbon dioxide is very soluble in liquid. That whatever beverage you serve under carbon dioxide pressure, it will eventually carbonate and you will get a sparkling water, soda, tea, coffee. The purity level of the carbon dioxide is also very important. Tri-State Carbonation Service only sells beverage grade CO2. This ensures that with properly balanced equipment, the beverage you serve is how it was intended.
Now for Nitrogen (N2). Nitrogen is a gas that is very insoluble compared to carbon dioxide. That means it is hard to get a liquid to absorb the Nitrogen. Typically, you use nitrogen for one of three purposes:
- to allow high pressure when dispensing the beverage through something that’s restricted like a beer tap;
- to allow enough gas pressure or a high pressure to push the liquid over a very long length of beer line; or
- to serve nitrogenated beverages like Guinness.
Sometimes beer lines run up to 120 feet from the keg room to the bar. This is where nitrogen would be used in combination with carbon dioxide to push the beer. To do that without losing carbonation or over carbonating the beer, nitrogen is generally mixed or blended with carbon dioxide. This is considered beer gas, you’re third gas. The carbon dioxide-nitrogen blend or mix is what allows the beer to travel over great lengths. This “beer gas” also allows kegs to be connected to a draught system under higher pressure without over carbonating.
The correct blend (or mix) keeps the beer at the correct carbonation level throughout the whole keg, no matter how long it is on tap.
Blended or Mixed Gas will:
- Keep a “nitro” beer properly carbonated and nitrogenated
- Keep beers properly carbonated, no matter how long they are on tap
- Prevent beers from going flat
- Reduce foaming problems due to temperature fluctuations.
Blended or Mixed Gas will not:
- Give your beer the creamy head of a “Guinness”
- Fix Beer that is already over-carbonated
- Eliminate all foaming in poorly designed, balanced or maintained dispense systems
Nitrogenated beers like Guinness require 25% CO2 / 75% Nitrogen whereas all other regularly carbonated beers will require 60% CO2 / 40% Nitrogen and in some cases 70/30 CO2 to nitrogen. These last 2 blends cannot be achieved stable over any period of time pre-mixed in a cylinder which is why blending the gases on-site as they are delivered to the keg is more effective and reduces waste.
You can also get more out of your nitrogen with a nitrogen generator. Nitrogen generators basically just take the ambient air and produce highly purified Nitrogen. They can also be used for your draught system but also a nitro-coffee station.
All beers have CO2 dissolved into them. Nitrogenated beer has N2 dissolved into it also. To properly serve nitrogenated (nitro) beers mixed gas must be used.

Controlling your pool’s pH with Carbon Dioxide (CO2)
There’s nothing quite like having a swimming pool in your back yard on a hot summer day. Kids laughing and splashing the afternoon away. Kicking back after work on a float letting your cares disappear.
That is until you decide to test the water! Sometimes it’s like being a mad scientist trying to balance your pool water. pH is too high, chlorine is too low, total alkalinity out of whack – where does it end? Water balance is the relationship of the different pool chemical measurements combined in the water.
The causes for out of balance pool water are varied: too much rain, pollen, too many swimmers and the list goes on. One of the toughest measures to balance correctly is pH because the ideal range is so small 7.4 – 7.6.
What difference does pH make? Well, the pH scale runs from 0 – 14, 7 being considered neutral. Anything under 7 and the water is acidic. This means the water irritates your eyes and nose as well as leaving your skin dry and itchy.
High pH levels – anything above 7.8 creates an alkaline level. This means the chlorine your putting in your pool for sanitation is less effective. You typically notice cloudy water when pH rises. The most common way to lower pH is with liquid muriatic acid, also know as hydrochloric acid. You may also use powdered sodium bisulfate (dry acid).
If you’d rather not mess with acids, then the easy way to keep your pool’s pH where it should be is with a CO2 injector. Hayward makes a model for both commercial and residential use. This system complements your automatic control system by providing hands-free operation and eliminates the need for acid feed pumps. These systems can also be combined with a liquid chlorine application from Wechsler Pool.

Some relationships run deep, and it’s interesting how they can become new business opportunities. That’s how the relationship between Wallenpaupack Brewing Company and Tri-State Carbonation Service began. The owners of WBC were long time Combined Energy Services propane customers. When Becky Ryman and her brother, Christopher, decided to take a hobby to a full-scale brewing operation, they knew who to call for their carbonation needs – Tri-State Carbonation Services, sister company of CES.
Located just north of Lake Wallenpaupack on Route 6, Wallenpaupack Brewing Company has been serving craft beer since September 2017 in their 12,000 square foot brewery. In their second year of operation, they were awarded the first ever “PA Preferred® Legacy” Award (2019) for their Wet Hop Farmhouse Ale. This award is given to a beer made with predominantly Pennsylvania-sourced ingredients. The award lent itself to the success of another local business, Hop Barons. Hop Barons, of Honesdale PA, are the growers of the hops used in the award-winning ale.
Fast forward another year and Ryman along with brewmaster Logan Ackerly have set some pretty lofty goals. Looking to double their 2019 production of 2,000 barrels, they seem to be on their way. With a wide variety of traditional craft beers including IPAs, stouts, Belgiums and lagers the brewery has also moved into hard seltzer.
We’re happy to have Wallenpaupack Brewing Company as a customer and look forward to many years of service for both their CO2 and propane needs. Visit them on Facebook @wallepaupackbrewingcompany.
