CO2 & Nitrogen Gas Tanks

If you own a kegerator, the one component you simply cannot do without is gas. CO2 or nitrogen are required for proper cooling, storing, and dispensing draft beer.

Therefore, a wise beer enthusiast should always have an extra CO2 tank or nitrogen tank for beer to keep it flowing continuously.

How to Choose CO2 & Nitrogen Air Tanks for Dispensing Draft Beer

Picking the right beer gas tank for your setup is not all that difficult – just follow these simple steps.

First of all, you should decide on the gas – carbon dioxide or nitrogen. Those who dispense regular types of beer should go with carbon dioxide tanks. If you’re planning to dispense Guinness beer or other stouts, nitrogen cylinders are required.

Next comes the size – CO2 cylinders and nitrogen tanks for beer come in the following varieties:

  • 2.5 lbs
  • 5 lbs
  • 10 lbs
  • 20 lbs

Most home-brewers prefer the 5-lb CO2 cylinder since it has the optimal size and weight. Plus, it’s really easy to carry around and transport if needed.

Finally, there’s a choice of material from which the tank is made – aluminum or steel. Most experts would agree that aluminum cylinders are better because they are more lightweight and resistant to corrosion.

How many kegs will a CO2 tank last? A 5-lb CO2 tank we’ve mentioned earlier typically lasts 6-8 half-barrel kegs before refilling.

What You Need to Know About CO2 & N2 Tanks For Kegerators

Both CO2 and N2 beer keg gas tanks are used to dispense beer, providing the necessary pressure to keep the keg carbonated and the beer flowing smoothly, without foaming.

These tanks come in various sizes, typically measured in pounds of CO2 or N2 they can hold. Common sizes range from 2.5 lb to 20 lb tanks (see above).

When a CO2 or nitrogen tank for a kegerator gets empty, it can be refilled or exchanged at local gas suppliers or homebrew stores. Many businesses offer this service, making it convenient for kegerator owners to keep their tanks full.

Where to buy CO2 tanks for a kegerator? Same place you refill them – at a local homebrew or gas supplies store. High-quality aluminum kegerator tanks can also be purchased online from Beverage Craft.

Homebrew CO2 Tanks

A nitrogen or CO2 tank for homebrew purposes is what people are usually after. One important thing to note here (apart from what we’ve mentioned previously) is that nitrogen tanks require a different type of regulator designed specifically for nitrogen dispensing.

Always check your kegerator specifications to ensure compatibility with the tank sizes and regulators you intend to use. Some kegerators may require specific types or sizes of tanks.
