In today's fast-paced business environment, ensuring a steady supply of gas—whether for industrial, medical, or commercial purposes—is crucial. Coregas Industrial Gases caters to these needs, providing reliable gas bottle and LPG refill services that keep your operations running smoothly. Regular refills are not only essential for uninterrupted service but also for maintaining safety and efficiency standards.
Types of Gas Bottle Sizes
Gas comes in various sizes, each catering to specific needs and usages. Coregas offers a variety of gas cylinder sizes, denoted by letters, with larger volumes and heavier weights associated with later letters like G size. LPG cylinders are instead labelled by weight in kilograms, such as 45 kg, with "FL" indicating suitability for forklift use. The smallest individual cylinder at Coregas is C size and the largest is G size, though this may vary depending on the gas type. Common sizes include D, E, and G. It's important to note that cylinder dimensions and weights can vary based on gas type, volume, and fill pressure, with all provided measurements being approximations.
For high-volume needs, Coregas offers cylinder packs, which consist of 6, 12, or 14 cylinders linked by a manifold, allowing continuous gas use from all packed cylinders, thus minimising downtime associated with cylinder changes.
