Beer Dispensing

Mixed Gas and Beer go hand in hand

For the brewer and the seller, dispensing beer using mixed gas has proven to be a valuable tool. Especially in presenting beer perfectly and consistently. For the brewer and the seller, mixed gas helps to deliver the beer as expected and is an important part of the overall brand image.

For the consumers, receiving the product as expected and to have the exact drinking experience they have paid for is very important. You want a product that is advertised and delivered with those expectations in mind. Mixed gas helps to provide that consistency from the moment the beer is first presented to the moment it is finished. Therefore making the consumer contemplate having another.

For the seller, pub landlords and managers there are other advantages too. Using the correct mixed gas can reduce all of the waste. Wasted gas and beer in the form of excessive foaming when it is stored and then poured. By controlling the conditions around the storage and dispensing of the beer you can give the presentation required and for the perfect dispense with little waste. These conditions include; the mixed gas that is used, the temperature it is stored at and selecting the correct dispense pressure.

You will be surprised at how much money the waste elements amount to over time!

More than enough to get a quick payback on a gas mixer system.

Mixed gas is of course available in cylinder supplies. However using 100% CO2 and 100% N2 and a gas mixer is much more economic than buying mixed gas in cylinders. A BSL Beer Dispense Gas Mixer delivers the quality and repeat-ability. It is also the cheapest way to get your mixed gas even in a very short space of time.

You can have any mix you feel you need from one of our Cellar-Mix Panels. A common mix to give you an idea are 30% CO2 in N2 for lagers. It varies of course and BSL have available calculations and data to help you select your mix.


The CF5000 package has three key parts. The Gas Mixer, the Gas Analyser, and the stand itself. The first part is the Gas Mixer, which uses the BSL Mass Flow Control Valves to make the mixed gas. These are well suited for this application, not least of all because they have a low pressure drop across them to produce high flows. What this means is that they can supply high flows of mixed gas even when you have some gases coming from other than liquid gas sources.

Nitrogen is increasingly delivered from Nitrogen Generators and this tends to be at pressures less than 10 bar g. The BSL Mass Flow Control Valves are perfect for this type of application.

The Gas Analyser is an optional item to back up the adjustable gas mixer. We have several options. Starting with a simple display and alarms to a more complex display, alarm, and output signals for use with your existing Management Control Systems and software for recording and reporting.

The third part is the very robust stainless-steel stand. It is deliberately made this way so that it can be washed down with cleaning fluids that will not damage it in any way. Those that would benefit the most are therefore food and beverage factories, where everything must be cleaned down periodically. The stainless-steel stand will cope with all the usual cleaning fluids.

In one particular Brewery, this package has been used in a number of areas of the plant. It has been used to feed the Keg Racking Area. Another unit has been used for blanketing the storage vessels. And outside of the factory another unit has been used to create the mixed gas to fill gas cylinders of beverage dispense gases reliably and accurately. A very versatile package!

4 Important Tips for Beer Dispensing

The Cellar — A clean cellar is key to keeping beer from spoiling before its best before date. Cleaning once a week with the proper sanitising products will prevent bacteria from growing. This in turn will also help the air quality and again help to stop the beer from spoiling.

Regular maintenance of your cellar will help equipment to run smoothly and effectively. Dirt, dust and mould can obviously have a negative effect on equipment.

Every night after closing, it is a good idea to turn of the gas to the beer lines. This will prevent the beer from being over-carbonated which causes fobbing and foaming.

Cellar Temperature — Most cellars will use remote coolers to bring the temperature down to the correct dispensing temperature and therefore the coolers should be running constantly.

Anything above 12 ̊C and bacteria can grow in the beer, making the beer foam more during dispense. Any harsh fluctuations in temperature can effect the beer quality of course.

Beer Lines — Same as your cellar, your beer lines need regular cleaning to prevent the beer from becoming infected with bacteria and wild yeast. These will cause the beer to spoil and create carbon dioxide, leading to fobbing and foaming. If the cleaning is not thorough, mould, limescale and beer stone can build up in the lines. This will affect the beer and even your dispensing equipment.

Beer Gas for Dispensing — Just like making sure your cellar and beer lines are clean, the gas you dispense with should also be clean.

BSL Gas Technologies Ltd make and supply Gas Mixers specifically made for the Beverage Dispense. Not only are our Gas Mixers accurate and efficient but they do not need an electrical supply either.  Saving on your electric bill! This also means you are less limited to where in the cellar you put it.

Because our Gas Mixers use a pressure mechanical  system, if a supply gas is lost, no gas will pass through the Mixer. Therefore, no wasted gas being pumped into the cellar.

We can also supply Gas Filters or have systems with the Gas Filters incorporated into them. Making your whole process more protected and clean.
