Size options

Our gases are available in a huge range of sizes, from small individual cylinders to huge bulk tanks storing gases in cryogenic liquid form

Coregas products are available in a range of sizes from single C-size cylinders to large bulk storage tanks, which can hold multiple thousands of cubic metres of gas in liquid form and are designed to supply gas via reticulated gas lines direct into your application or throughout your site or hospital.

Typical cylinder sizes

Individual cylinders

Most gases in the Coregas range are available in individual cylinders in a range of sizes. The sizes available depend on the gas type.

With the exception of LPG, cylinder sizes are designated by letters of the alphabet: the later in the alphabet, the greater the volume of gas and the heavier the cylinder. For instance, G size cylinders are larger, heavier and contain more gas than E size cylinders, which are larger than D size and so on. The smallest size individual cylinder available from Coregas is C size and the largest is G size, but this varies depending on gas type. The most commonly used sizes are D-, E- and G-size.

LPG gas cylinders are generally designated according to their weight in kilograms, eg 45 kg. The addition of the abbreviation "FL" indicates it is suitable to be used to power forklift trucks.

*IMPORTANT: Cylinder sizes and weights vary widely from cylinder to cylinder and also depend on the gas type, volume they contain and fill pressure. It is therefore important to note that all dimensions and weights in the tables below are approximate values only. Weights are for when the cylinder is filled with gas. If filled with liquid, they will weigh more.

Cylinder packs

For gas usage that is larger in volume than single cylinders, the next size up is cylinder packs.

These consist of groups of 6 or 12 G-size cylinders housed in a specially-designed pallet and frame with the cylinders connected together with a manifold, which enables your application to draw gas from all the cylinders using only a single connection to the manifold.

Cylinder packs are a great way to reduce downtime from swapping cylinders over because you use the volume from all 6 or 12 cylinders before needing to swap to a new pack.

Be advised that there is variability across the fleet with dimensions so please confirm with your account manager of any restrictions. Please also consider height considerations if using pallet jacks or any other mechanical lifting devices, as this may require additional tolerance requirements to ensure there is height clearance.

The dimensions of both packs are roughly the same because both sizes are installed in our standard size pallets:

Bulk supply and cryogenic liquids

For large volume users, there are multiple options available which store liquefied gas at cold or cryogenic temperatures. Fourteen products are available in liquid format:

This liquid is converted to a gaseous state just prior to use and supplied in to your application or around your site via a reticulated pipeline system. If required, Coregas' experienced engineers can design, install and provide training on how to run a reticulation system customised for your application.

Available storage options include storage tanks in a range of sizes, from small vessels known as microbulk to huge 100,000 m3 bulk tanks capable of constant supply to the busiest of applications. Plus for gases such as hydrogen or carbon dioxide, we can supply mobile trailers of gas so no permanent installation is required.

Depending on your application and requirements, Coregas can deliver set volumes on a regular delivery schedule, deliver when you place an order or we can manage the complete process for you.
