How to Change a Cellar Gas?

Here are the steps to follow to change your cellar gas. Any gas cylinder, despite its capacity, the frequency of use and the power of your appliances, will be eventually exhausted. The moment dreaded by many will, therefore, arrive that of changing the cellar gas.

Although it may seem tricky, everyone is able to change their cellar gas autonomously. Although this task is easy, it does require you to take some precautions, detailed here in a few steps. The necessary materials are as follows: a regulator adapted to your bottle, your new gas bottle and a new connection joint.

Before any change of a gas cylinder, some safety rules must be observed: do not use pliers, this may damage the connection joint.

Make sure that the expiration date of your connection pipe is not exceeded. Check that your hoses are in excellent condition using a foaming product or a gas leak detector aerosol. Make sure that the gas supply valve is operable at all times and that the room has non-obstructed air vents.

The legislation requires the replacement of potentially hazardous rubber-soldered taps or hoses with flexible hoses with integrated automatic shut-off valves. Check that your hoses meet the current standards. Your gasket must be specific to the type of gas you use.

Change the seals of the connecting pipes regularly. Storage of gas cylinders in an inappropriate area is strictly forbidden, please ensure that your gas cylinders are stored appropriately.

After performing all of the above checks, you can complete your gas cylinder change safely by following these steps. The stages of the bottle change are as follows:

Remove your old bottle. Separate the connector between the regulator and the cylinder by unscrewing it. You can take this opportunity to check the expiration date of your hose connector. Close this valve if the bottle is equipped. Remove the empty bottle from its location for easier access to the gas supply valve.

Prepare your new bottle. Unscrew the carrying handle. Then remove the protective plastic end cap from the outlet valve. Your bottle is ready to be connected.

Change your seal. To avoid any risk, it is strongly advised to change the seal with each bottle replacement. To do this, unscrew your connector pipe, then screw it back once your joint has been replaced.

Connect the hose to the new bottle. Connect the hose to the appliance. Screw the regulator to the hose. Attach the regulator to the valve outlet.

Open the faucet. Open the cylinder valve. Reset the regulator. Perform a leak test on the various fittings with soapy water or a test product Replace your bottle in its compartment. Your bottle is now ready for use.

Can Beer Be Served From a Keg Without Gas?

It can happen to anyone, at any time. A delivery man sets a stack of kegs on a gas line in the basement and a ham-fisted barkeep, moving one of them, breaks a tap. Even worse, a connector shows its age by blowing a gasket during the busiest night of the week, and there you are, with a keg that’s nearly full and no beer gas to push it with when you need it the most. Is there any way to get around this problem? There are several ways to make this work in a pinch, but the optimal solution is always going to be a properly working system, with clean lines, good connectors and plenty of cellar gas to minimise the chances to gas system breakage.

If the keg was already pressurized with gas, and is already mostly used up, you can probably finish pouring some or all of the beer out of the keg without the need for more gas. This assumes there was no broken connection and that the keg is still airtight.

If the keg has never been connected to the gas, or a connection broke and released some or all of the pressurized gas before you got it disconnected, all is not lost. Remember, there is plenty of carbon dioxide in the beer itself. You could shake the keg vigorously. This will pressurize the keg with carbon dioxide that escapes the beer during the shaking process.

However, it’s only going to work for a short time, depending on how often you’re pouring, and it’s only going to work on a keg that isn’t completely full, but still has over half its contents remaining. With a full keg, there isn’t enough volume of air to pressurize the entire contents of the keg, and with less than half, there is too large a volume of air and the remaining beer gas will dissolve itself back into the beer, resulting in no usable pressure at all.

This leads us to the last and most desperate measure. You must turn to physics. Even the most luscious beer cannot escape the laws of fluid dynamics. Siphon the keg. Here are the steps involved:

1. Lie the keg on its side, possibly on a crate. Point it at a wall, drain or container to catch any remaining pressurized contents that might spew out. Raise the bottom of the keg slightly above the top with a block, and make sure the in-flow port is oriented towards the floor.

2. Attach a connector and tubing, or a hand-pumped picnic tap to the in-flow port on the keg. Make sure to block or pinch this tubing in some way so that you can use it to dispense the remaining beer.

3. Attach another connector and open-ended tubing to the beverage out-flow port, which should be oriented towards the ceiling. Make sure to keep the open end of this tubing above the keg at all times. Its purpose is to provide an air inlet so that the beer can gravity-feed out of the in-flow port to empty the keg.

These are only temporary solutions to this problem. The only true answer is to put your system in working order, make sure the lines are clean, and order some high-quality beer gas. Your kegs and your guests will both be thankful.

How to Store Co2 Cylinders

CO2, carbon dioxide, is probably best known as the gas humans breathe out and the one plants need to survive. Its application extends beyond breathing, however; carbon dioxide is used in several sorts of businesses for multiple reasons. Usually, this means storing it in a cylinder.

To further explain, carbon dioxide cylinders keep the compound contained at a specific pressure for practical uses. This can be in either liquid or gas form, depending on how a business intends to use it. Though CO2 is typically poisonous to humans when breathed in, this isn’t an issue for most businesses. Carbon dioxide stored in a cylinder with a valve for controlled use can be used for purification, medical stimulation, pH control, and more.

However, CO2’s most popular application may be in food and beverage arena. When sealed in a cylinder, it can be used for cooling and freezing food, as well as preserving flavour and reducing the need for chemical preservatives. It goes without saying that carbon dioxide is essential for carbonated drinks. For pubs, bars, and restaurants, carbon dioxide is quite the must-have “ingredient.”

Dealing with CO2 cylinders is no small matter, however. They weigh 16kg empty on average, and they’re around 20kg of metal and potentially toxic material when they’re full. In keeping them well-stored, start by picking an area that’s cool, clean, well-ventilated, and away from elevation. Don’t place them anywhere where there’s a lot of traffic, as this will increase the likelihood of cylinder damage. Be sure that they’re easy to reach, but secure where they are.

Next, keep the cylinders in positions of safety. Leave them on their base or lying on their side, their valves sealed tightly; any equipment they came with should remain nearby. Refrain from putting the cylinders in moving vehicles or near electrical circuits. Obviously, the cylinders shouldn’t come into contact with percussive force, either, lest the cylinder or people get hurt or damaged in the process.

Perhaps most important is to remember that the carbon dioxide is pressurized. Mishandling they can create leaks or bursts of such strength that all sorts of damage can take place. Move them carefully, use protective wear, and don’t lift more than you can handle. If you need a trolley or lift to move cylinders, take the precaution. Try not to have more cylinders than you need, and return used up containers to the business from which you purchased them.
Despite its many uses, carbon dioxide must be handled with care. Move the cylinders carefully, protect them from external damage, and store them somewhere away from a threat. These units are more delicate than they appear, but as long as you mind how you handle and store them, your business shouldn’t hurt for it.

How to Choose the Best London Pub Gas Supplier?

3 Tips on Finding a Good London Pub Gas Supplier for Your Pub Gas Supplies

Opening up a pub is a challenging task. You have to find all the best suppliers and the best investor. Part of this process involves finding the best London Gas Supplier for your beverages. Many of your beverages may contain gas products. In order to supply the gas in these drinks, you need an adequate cellar gas chamber to hold the product.

London Pub Supplier

All of this requires extra time and research on your London gas pub supplier. Your London Gas supplies need to be at a premium. Below you will find 3 tips on how to ensure your pub gas supplies maintain their premium status, thereby guaranteeing your loyal customer base.

1) The wholesale industry will equal about 25% of your business. You need to make sure your wholesale suppliers are top-notch. There is a big difference between doing business with your wholesaler and all other business entities. You want your relationship with your wholesaler to work out. You need to have a good relationship and complete trust with your wholesaler and all other manufacturers you are dealing with.

2) It is all about the volume. The more you buy from your wholesaler, the lower your price will be for the whole lot. This will have an impact on your sales. The more drink products you are offering, the more your sales will increase.

There may be a specific person you are interested in doing business with. Talk to those who know them. Talk to those who have done business with them. Does their brand match up their reputation? Your customers will be able to tell the difference between a cheap drink and an expensive one. Most London pubs do not like to sell cheap imitations of the real thing. It tends to reduce their customer base and loyalty. This is something you need to think about for your business.

Do not skimp out on the price of what a brand costs. You have a reputation too. Do you want your customers to keep coming back? You need to choose brands that will push your sales and reputation in the right direction. Volume has more to do with it than you think.

3) Please do your own research on the people you choose to work with. Do not leave it up to the third-parties you talk to. You also need to take a look at the agreement you map out with your wholesale dealers and manufacturing companies. Read all the fine print before you sign. They may have added something in you do not know about.

reading over the entire contract os boring and time-consuming, but it is necessary. You cannot take the person on their word. The days of the honest handshake are gone. People are much sneakier these days. Your manufacturer may want a bigger piece of the pie as your sales increase. He is not going to tell you this. He is going to sneak it in. This is just one of many examples, but it makes the point.

What Is a Cellar Gas?

One thing that makes a bar great is its selection of drinks and gas is one of the reasons that bars can serve an ice cold glass of beer that is always sparkling. If you have a business like a bar or a pub, you should know what cellar gas is and how it can be a cost-effective solution for your business. A CO2 cellar gas can be used for a variety of purposes in a safe efficient manner to enhance any drinking experience for any bar or pub.

What is Cellar Gas?

When you sit at a bar and you get served a freshly poured pint of stout that came directly from the tap, the feeling, and the mood is totally different from a server that just brings you a cold bottle of beer. This is all made possible with the use of gas. This type of gas is a mixture of carbon dioxide and nitrogen which helps enhance the drinking experience for beverages like beer or soft drinks. It is safe to handle, easy to use, and extensively tested to cover a wide range of uses and industries, particularly bars and pubs.

CO2 pub cellars gas usually comes in the form of 10-liter cylinders that are regularly maintained to British industry standards. Some cylinders are CO2 only while others are a nitrogen/CO2 mixture. Many bars and pubs are now trending towards “Nitro Beers” which uses gas that contains 70% nitrogen and 30% carbon dioxide to help create a type of rising effect that is topped with the head of every beer that is served.

An Improved Beverage Presentation

These cylinders operate at the maximum pressures used in the industry today. This means that every time you serve a beer, it will always come with a mesmerizing cascading effect and waterfall of tiny bubbles that slowly yield to a white thick head. The type of gas that is used will set the difference between the look and taste of beer when it is served.

Cellar and beer gas solutions also come with accessories that use state-of-the-art equipment that will help you save, money, time, and space. Regulators are used to maintain carbonation and pressure as well as dispense draft beer and postmix drinks. CO2 versions are regulated to the industry standard of 30% and 60%. Blenders are also installed on compact walls next to other gas equipment and this accessory helps to create the ideal dispensing conditions for your bar or pub.


With the proper installation of a pub cellar gas system, further benefits include:

How It Can Be Used

Carbon dioxide gas makes can beers and ciders taste fizzy with a prickly biting sensation on your tongue when drinking them. Nitrogen gas makes beers taste creamy and when you pour them into a beer glass it will have a beautiful swirling effect. Many pubs and bars commonly use what is called “30/70 mixed gas”.

Cream flow and smooth flow beers like Guinness or John Smith’s Extra Smooth work well using a mixed gas that has a high nitrogen content and low carbon dioxide content. These bottles are also convenient since they are ones that are commonly ordered because all mixed gas comes in one bottle. There are also different bottle mixes and sizes and choosing the right one will depend on your needs. For a business that is just starting out, a 30/70 mix is a great way to go because it works with a wide range of beers to enhance their taste and appearance.

Getting in Touch With the Right Supplier

When choosing a gas provider, there are a few things you should consider. One point you should look out for is making sure that the provider you choose is cost-effective for your business. Whether it is small, medium, or big, your business should look for the best provider for gas services to include filling their cylinders at their own depot. This service should also be able to provide its own fleet of drink dispense gas cylinders to include:

If you own a bar or pub and you are ready to take your business and the drink menu to the next level, you should introduce a new variety that customers will enjoy using cellar gas. With the right gas mixture, you can ensure your customers are getting the best product.

What Is a Co2 Cylinder

Co2 Cylinders for Bars and Pubs Explained

Bars and pubs that serve drinks such as beer and soft drinks in the London area prefer to use CO2 cylinder gas. Knowing all about a CO2 gas cylinder will enable you to make the ideal choice for commercial dispensing when it comes to beers, lagers, stouts, ciders, and carbonated drinks. Finding the right CO2 tank for your business is the first step towards taking your drink menu to the next level. Once you know how it works, you will be ready to make a new beverage design plan while always keeping safety in mind.

What is a CO2 Gas Cylinder?

Compressed gasses such as carbon dioxide, nitrous oxide, and oxygen are all gasses at room temperature. However, once these gasses get cold enough they become a liquid and this is how they are stored in gas containers. When these liquids experience a temperature increase, they also expand in volume. This is why it is a safety issue when handling these tanks because the CO2 pressure increases when the tank gets hotter. A CO2 regulator is also important to have to keep your tank from heating up drastically.

A gas cylinder is the beginning of the pressure side of your draft beer system. It is important to understand how CO2 provides the pressure to your system using a CO2 gas cylinder in order to know how your draft beer or other types of beverage delivery systems work.

A gas cylinder is usually made of aluminum so that it is lightweight and corrosion resistant and comes with a fitted valve so that it can turn on or turn off the flow of gas in the cylinder. They also come in a number of sizes and for ease of use in bars and pubs, it is a good idea to stick with 2 ½, 5, 10, 15, or 20-pound gas compression chamber depending on your setup and need. Since you will be moving, transporting, and storing the cylinders, size is a definite factor you want to consider when purchasing CO2 beer gas or any other type of CO2 tank.

At 880 pounds per square inch, the CO2 has lost enough energy and is cold enough to turn into a liquid. This liquid form is what the CO2 is when it is inside the gas cylinder and it remains in this state until the cylinder is opened. You should take note that the pressure of your cylinder should always be 880 psi and this is the pressure that is the driving force for your beverage delivery system.

You should also keep in mind that the tank is only providing storage at this pressure and once it is opened, the liquid will evaporate and become available to flow into the gas side of your beverage delivery system. The pressure is reduced by the attached regulator so that the released gas can be used at a more manageable level.

The top valve can easily be opened by turning the hand wheel or valve handle in a counterclockwise direction. Likewise, it can be closed by turning clockwise until it stops. You will also see a pressure relief valve that is built into the body of the valve. When the pressure rises above a preset level, the pressure release valve will automatically discharge the cylinder. There is also a threaded outlet that allows you to attach a regulator the valve body.

Pubs and bars usually use a filling service to refill the containers when they are empty. These services are helpful because they provide an extra cushion of safety since they regularly inspect the for damage and routinely check their last hydrostatic test date.

Any cylinder you use should have undergone a rigorous battery of hydrostatic testing. A cylinder that has not been tested within the last five years should not be used. In addition, you should never accept nor request to fill a damaged cylinder.

How It Works

CO2 expands rapidly when there is an increase in the tank’s temperature. This increase puts more and more pressure on the gas regulator which is also controlling the CO2 output. The CO2 liquid inside the tank is very cold (-57 to -78 degrees Fahrenheit). When the liquid is very cold, CO2 only puts off about 100 psi (pounds per square inch). At room temperature at around 70°F, the tank has an output of 850 psi. At hot temperatures around 110°F, the tank can have an output of up to 2000 psi.

Make a Design Plan

One thing you will need to consider in your design plan when getting a CO2 beverage delivery system is determining how much room you will need for your CO2 tank. The quality of your beer carbonation will depend on your CO2 canister and how well you can keep the beer keg cold. Keeping the keg and the canister at lower temperatures will help infuse your beer more efficiently.

Providing enough space for CO2 beer gas cylinder will ensure that your beer is not too foamy when it grows a head after pouring it into a glass. You also be able to have better control and maintenance on carbonation that is present in the beer you serve.

The size of the beer keg is also a consideration because you will need enough space for both the CO2 tank and the keg. The most basic bar and pub set up is where they use an external CO2 tank that is connected directly regular beer kegs. Sometimes the kegs will sit on ice or a kegerator (a conversion of a refrigerator for a keg) to stay at cold temperatures.

Safety Considerations

You should always remember that a CO2 cylinder is a powerful tool and must be treated with respect. It is always important to follow the proper safety guidelines when handling these tanks. You should also make sure that the regulator pressure is never turned up higher than recommended. Another tip is to make sure that cylinders are always standing upright when in use.

Finding the Right CO2 Tank for Your Business

Owning a bar or pub gets exciting when you find the right CO2 cylinder that will help you serve more outstanding drinks to your customers. Making your drink menu more exciting with CO2 may be just what you need to get an extra edge over other competitors.

What is Liquid CO2 and What Can It Be Useful For?

Liquid carbon dioxide is carbon dioxide gas that is highly compressed and cooled to a liquid form. Carbon dioxide exists as a liquid below the critical temperature of 31C and above the triple point with a temperature of-56.6 C and 4.18 bar.

Generally, CO2 gas is transported, stored and handled in liquid form, either in cylinders or non-insulated storage tanks at a pressure of 45-65 bar or refrigerated tanks at temperatures between -35 C and -15 C and pressures of 12 to 25 bar. Demand for liquid CO2 in various industries has grown tremendously. This is a reflection of the diverse applications of this gas.

Liquid CO2

Liquid carbon dioxide is widely used in the entertainment industry to achieve special effects. With liquid co2, many special effects are easier and economical to achieve. Without it, it would require expensive pyro technique equipment to produce these effects:

Haze effects: Liquid CO2 is used to create homogenous cloud effects in TV production. These clouds are used to reveal lighting beams in a music concert. The gas serves to accentuate the effect of spotlights. The cloudy effect is produced by passing compressed c02 through a reservoir of highly refined mineral oil.

Fog effects: You have seen movies with foggy scenes but they were probably filmed in a sunny desert. Liquid carbon dioxide is used together with fog machines to produce a low-lying fog effect. Liquid CO2 is used to cool theatrical fog produced by the fog machines. The fog remains close to the ground when it is cold but when it warms it disperses evenly.

Food preservation

The importance of pressurized C02 in the food industry cannot be underscored enough. The food industry largely relies on this liquid gas for refrigeration, preservation, storage and softening.

Cooling agent: Liquid co2 is used as an important cryogenic cooling agent. It is used directly as a food preserve and in cooling applications where it maintains the food at constant at temperature. Liquid carbon dioxide is also used during the transportation of ice cream. It is preferred because of its high volumetric cooling capacity.

Softening drinks: Compressed carbon dioxide gas is largely used in the production of soft drinks. Carbonation of drinks first happened by natural fermentation, but today bottled drinks are softened and preserved using pressurized co2. Liquid C02 is also used to remove caffeine from coffee because it is a versatile solvent.

Fire extinguisher

Liquid Carbon dioxide is used as a fire extinguisher because of its anti- flammable properties. The gas works by starving the flames of oxygen, which is the gas that supports burning. Fire extinguishers used to put out electrical fires are specifically filled with liquid carbon dioxide. This is because apart from putting out the fire by eliminating oxygen, the pressurized gas cools the burning surfaces preventing further damage.

Oil recovery

In oil recovery, the liquid is pumped into oil wells where it becomes miscible with the oil. It reduces the viscous nature of oil and causes it to flow easily to the point of removal.

Liquid co2 is a versatile gas with many applications. Perhaps the most prominent ways it is used today is in the food and entertainment industries.
