The Total Cellar System

A Nitrogen Gas Generator is at the heart of the ultimate dispense gas solution. An Apex system gives you the high quality, reliable mixed-gas supply you need for faster beer dispensing, reduced fobbing and consistent pint presentation. Today's cellar systems rely on bottled gases of multiple elements and mix ratios, which can be potentially hazardous to store on-site, not to mention the high cost of renting multiple bottles. Furthermore, the headlines constantly remind us of the harm green-houses gases (like CO2) are having on the environment, it is becoming even more important to be planet-friendly. Our GasgeN2 system moves from relying on CO2 to putting nitrogen at the centre of your system. A nitrogen generator produces nitrogen which can be used in your cellar pumps or mixed with carbon dioxide on-site to provide the gas ratios required by your beers. 


We mix your gas on-site, giving you the right ratios as you need them. Mixing on-site provides you with a cost-effective method for offering a wider arrange of beers. We can also tailor the mix ratios to your cellars needs, ensuring only the very best pint from first to last. You no longer need to buy and rent bottles of expensive mixed gas that you rarely use. Limiting waste and reducing cost while maintaining the quality you are used to.

The right ratios are made to order. Allowing you to offer a wider range of beers at a lower cost to you.

Carbon Dioxide is all you need, lowering your rental costs, saving you money!

Fewer Bottles

Fewer Bottles

This system replaces the need to buy and rent a variety of gas ratios, by mixing them onsite we are able to produce the same ratios from only bottled CO2. This means you need fewer bottles, saving you money in rental fees. Not only do you simply need fewer bottles, but you will also use less bottled gas. Our system, unlike most, puts Nitrogen at its heart. We use the nitrogen generated by our machine to power the pumps. Our system uses nitrogen whenever possible to reduce waste. The final arm of our system aimed at saving you money involves moving you to a cheaper rental agreement for CO2.


For a fixed monthly cost, you have an unlimited supply of nitrogen.

A nitrogen generator does exactly what it says, our system generators nitrogen as you need it. It produces nitrogen from the air surrounding it, after being cleaned by medical-grade filters. The generator should be able to keep up with demand. For additional peace of mind, our generators come with a low-pressure tank ensuring you can deliver the perfect pint all day long. Low-pressure tanks store the nitrogen just above atmospheric pressure, making the tanks far safer than highly pressurised cylinders.  With your gas being made on-site there is no downtime and no expensively delivery charges to worry about.

Dispense Gas Suppliers make their money from you buying gas and therefore want you to be using has as much as possible, we don't take the same view. The generator is the core of our system, for the same monthly fee provides you with all the nitrogen you need, it is abundantly found in the atmosphere and causes no harm to the environment. We don't profit from your gas usage and as a result, we are actively looking to reduce your systems reliance on Carbon Dioxide both because it is beneficial to you and because it is better for the environment. The headlines constantly remind us of the damage we are causing to the planet, wasting bottled CO2 plays a part in that. Do your bit to lower your impact on the environment and partner with us. The only consequence to you is cheaper gas - not much of a downside.   

Fewer bottles equal less delivers, just one of the eco-benefits of our system.

The most expensive part of any cellar gas system is the purchase of gas, specifically the cost of expensive mixed gas. The Apex system is designed to lower those costs. Nitrogen is produced on-site and is then mixed with bottled carbon dioxide to produced the right mixed gas for your system. This brings two key benefits; 1) you only need to buy bottles of carbon dioxide which is the cheapest dispensed gas and 2) the nitrogen can be used to power your systems beer pumps meaning that CO2 is only used in your drinks making it last longer.

We are constantly working on improving the system and developing new technologies to improve the delivery of our service. If you take out a subscription package with us then improvements come included. When we do our best it allows you to do yours. 

See How the System Works

Generating nitrogen onsite allows our system to use it whenever CO2 is not required. CO2 is important for the taste and texture of a lot of beers and therefore little can be changed about the mixed gas currently used in your system. But where you previously used CO2 or mixed gas in powering beer pumps or in cleaning lines, our system can use the generated nitrogen, saving bottled gas to be used in beers only. This makes your bottled gas last longer and means you need fewer bottles in your cellar, saving on rental costs.

Don't worry about gas quality, the nitrogen is produced by a generator using medical-grade filters and tubing. The generator is tested to produce nitrogen of 99.9995% purity, you can rest assured the nitrogen produced is the best there is. To ensure your system is running at its best we will make regular visits to check the generator, change filters and ensure the generator is continuing to produce the high-grade nitrogen, its all part of the service.

It is reported that 4.2 million deaths a year are attributed to air pollution (World Health Organisation, 2020). While in quarantine due to the coronavirus the world has stopped and the impact on the environment can be seen everywhere. With airlines grounded, roads empty and factories closed there has been a massive reduction in air pollution. Since Italy went into lockdown on 9 March, pollution levels in Milan and other parts of northern Italy have fallen by about 40% (European Space Agency, 2020). Scientists believe that reducing pollution due to the lockdown has saved an estimated 77,000 lives in China alone just by reducing pollution (McMahon, J., 2020).

No one is suggesting that the coronavirus epidemic is a good thing nor is there a silver lining to them, but maybe they help us to learn about things we do in our everyday lives that could be improved. We should be trying to learn from this crisis and work to reverse the damage we have caused. Granted the biggest changes need to be made by the biggest polluters, fossil fuel burners, airlines and traffic. But that isn't to say that you are not able to make a difference.

Here at Apex, we believe we have the service which allows you to do your part, to do good by the earth and reduce climate change. That is exactly what our Cellar Gas System does. An upgrade of the inefficient and heavily polluting bottles gas model. Shifting the focus of the system onto Nitrogen allows you to be more environmentally friendly, as you limit wasting of CO2. Our system is designed to require fewer bottles of gas and use them more efficiently, this results in fewer deliveries which further reduces your carbon footprint - not to mention the financial benefit.
