Co2 and Bulk Systems – Co2 cylinders and Bulk Systems come in a variety of sizes to suit a multitude of business needs. Please speak to your One Source Gas expert to evaluate your usage-trends and help your company to determine what option will work best for you.

Nitrogen and Nitrogen Bulk Systems – N2 is a naturally occurring gas that is insoluble in beer. Nitrogen has two similar purposes for us with draft beer: (1) to allow high pressure dispensing through a heavily restrictive apparatus (causing notable frothing) as in Guinness and similar products; (2) to allow high enough gas pressures to overcome the resistance inherent in long beer lines. In both of these cases, the goal is to push the beer at high pressure, but not alter the carbonation of the beer as it sits in a keg. This is accomplished by using insoluble nitrogen mixed with the soluble Co2.

Argon – Often used by brewers to protect wort (unfermented beer) and beer from oxidation. It is also widely used in winemaking. This is an inert gas that is relatively insoluble.

Beer Gas – Beer gas is a blend of carbon dioxide and nitrogen used in draft systems. The presence of nitrogen results in smaller bubbles than carbon dioxide alone. This produces beer with a denser head and a creamier mouthfeel. Beer gas is popular with darker styles of beer such as stout. 

Helium – Our small helium tanks will fill up to 400 9″ balloons and large tanks up to 750.


One Source Gas performs beer diagnostics on any system to help ensure a perfect pour every time. The perfect pint helps to maximize profits by reducing waste and standardizing the flow rate. Each system is unique and requires careful attention to detail to ensure all variable are within the optimal limits. Call or contact us today to have a representative come out to your establishment to ensure quality draft beer.

Beer Systems are an investment, and to ensure they last as long as possible and consistently operate with the greatest efficiency takes maintenance. Our experienced professionals are capable of providing service for your type of system that will maximize both its life and the quality of its product.
