There are various kinds of CO2 cylinder 2kg available in the market. They vary depending on the nature of the application in which they are going to be used. Here are some common types:
Standard Steel Cylinders
Steel co2 cylinders are the traditional and most widely used types. They have been used over the years since they are very strong. Furthermore, they can be used in many applications including beverage dispensing, welding, and filling fire extinguishers. Steel cylinders are suitable for high-pressure storage. Thus, they have a threaded valve which can be used to control gas release.
Alu Cylinders
Alu CO2 cylinders are lightweight alternatives to steel cylinders. These are commonly used in portable applications where carrying the cylinder around is a necessity. Alu is less durable than steel. However, these cylinders are rust-resistant. This makes them ideal for marine environments or areas with high humidity.
Composite Cylinders
To manufacture composite cylinders, manufacturers will use a combination of materials such as fiberglass and plastic. These are lighter in weight as compared to steel cylinders. They are also designed to be used in specific applications. These include scuba diving tanks or high-performance industrial settings. They are also corrosion-resistant. This gives them a better advantage over steel in outdoor applications.
Refillable Cylinders
Cylinders 2kg that are refillable are designed for continuous use. They are often found in beverage industries, commercial greenhouses, and farms. Once the gas inside is used up, the cylinder can easily be taken back to the depot where it will be refilled. Filters are fitted on these cylinders to prevent any contaminants from getting in and damaging the cylinder.
Non-refillable or Disposable Cylinders
These are usually smaller CO2 cylinders. Most times, they carry a volume between 2 to 5 kg. They are designed to be used once and then replaced. They are mainly used in portable or low-consumption applications. Such applications include inflating devices or small aquariums.
Safety Features Cylinders
These CO2 cylinders include safety features such as pressure relief valves or burst discs. These features will help mitigate risks of explosion in cases where the pressure has suddenly increased. These are mainly used in industrial settings where high-pressure operations are carried out.
The design of the CO2 2kg cylinders will vary depending on the application in which they are going to be used. However, every cylinder has some common design elements, which are explained below.
Material Composition
Cylinders are usually made of steel, aluminum, or composite materials. Steel cylinders are forged out of a single piece of steel. Normally, they will be heavy and very durable. Alu cylinders, on the other hand, are slightly lighter. They will have similar strength but will be more resistant to rust. Composite materials include materials like fiberglass. They are preferred because they offer significantly less weight but equal strength.
Cylinder Dimensions and Size
A 2kg CO2 cylinder’s size and dimensions are normally ascertained by the pressure it is operating at. Usually, most of these cylinders will be at a standard pressure of 150 bar. This translates to around 2,200 psi. However, there are a few low-pressure variations. For example, C02 cylinders designed for fire extinguishers. They will have wider diameters but shorter heights. The typical height range of high-pressure CO2 cylinders is around 60-70 cm. Their diameter is normally around 15-20 cm.
Valve System
Cylinder valves are responsible for controlling the CO2 gas’s release. Generally, they come in different designs. The most popular types are the CGA320 and DIN valves. They are threaded. Users open or close these valves by twisting in a clock or counter-clockwise manner. Safety is also integrated into valve systems. There are pressure relief valves that will help release excess pressure when it gets too high.
Surface Treatment and Coating
To prevent corrosion, CO2 cylinders are fitted with surface treatments and coatings. For steel cylinders, the exterior surface is coated with a layer of paint. Usually, it’s a layer of anti-corrosive paint. Aluminum cylinders will either be anodized or have a layer of specialized coating. Composite cylinders don’t require any surface treatment or coating. This is because they are already corrosion-resistant.
Cylinder Markings and Certifications
Every CO2 cylinder comes with specific markings and certifications that ensure its safety. These certifications will normally include the test pressure, date of the last inspection, and the owner’s details (often a number). In such certificates, there are also warning labels about the dangers of CO2 gas and the proper usages of the cylinders.
CO2 cylinders are used in various applications in different industries. These applications require the cylinders to be portable and fillable. So, here are some common uses of 2kg CO2 cylinders:
Beverage Industry
The beverage industry will utilize CO2 to carbonate water and soft drink beverages. Therefore, they use these cylinders to supply the gas in bars, restaurants, and commercial kitchens. When users dispense drinks, the CO2 will be injected into the liquid. This creates the carbonation everyone loves. CO2 canisters are also used in brewing processes to help with the stability of the beer during production.
Agriculture and Horticulture
The agriculture and horticulture industries particularly use the 2kg CO2 cylinders in greenhouses. Here, the gas will be used to boost the photosynthesis process of plants. This will, in turn, improve crop growth, yield, and quality. Farmers who produce crops like tomatoes, cucumbers, and peppers use these cylinders to inject CO2 into their greenhouses and control the atmospheric levels. Additionally, these cylinders are used in equipment for applying carbon dioxide as a pest control method.
Fire Extinguishers
CO2 fire extinguishers are normally preferred in spaces with valuable assets. These spaces include computer servers, libraries, and archives. It is because the extinguishers don’t leave any residue behind after use. This makes 2kg CO2 cylinders a critical component of these extinguishers. They will be applied during fire suppression to eliminate oxygen around the fire and displace it.
Industrial Applications
CO2 has a plethora of uses in industrial processes. For instance, it is used for cutting and welding metals. It is also used for purging and deoxygenating storage tanks and pipelines. In packaging, it acts as a shielding gas to improve the quality of the weld. Moreover, the ideal inertial properties of this gas make it suitable to create a vacuum in glass containers.
Aquarium and Marine Systems
CO2 is essential in aquariums that are run using a system called planted tank. Here, the gas is injected into the water to enhance the growth of aquatic plants. It helps keep the plants healthy and improves the overall aesthetic appeal of the aquarium. In larger marine systems, the cylinders are used to maintain optimal CO2 levels and ensure a balanced ecosystem that supports fish and plant life.
When purchasing a CO2 2kg cylinder the buyer has to consider the following key factors to ensure they get the right product each time:
