Nitrogen generators for beer systems have been gaining popularity in recent years due to their ability to provide a consistent and high-quality nitrogen gas supply for dispensing draft beer. Nitrogen generators work by extracting nitrogen gas from the air and purifying it to a high degree of purity, which is then used to pressurize beer kegs and create a smooth and creamy pour. This method is preferred over traditional beer gas and gas cylinders alone, which can be costly and require frequent replacement.
Nitrogen generators for beer systems are especially useful for nitrogenated beers such as Guinness, which require a blend of 75% nitrogen and 25% CO2 for optimal dispensing. However, nitrogen generators can also be used for most ales and lagers, with a blend of 70% nitrogen and 30% CO2 being the most common. Custom blends are also obtainable for specific beer styles or preferences. In addition to beer, nitrogen generators can also be used for dispensing wine systems, as well as coffee and other beverages.
The benefits of using a nitrogen generator for beer systems extend beyond just the quality of the pour. By using a nitrogen generator, breweries, and bars can save money on gas costs and reduce their carbon footprint by eliminating the need for frequent gas cylinder replacements.
