Gas cylinder

October 1, 2011
These 116-liter gas cylinders are slightly larger in size than the popular 58-liter gas cylinders, but hold twice the volume of gas. Larger cylinders need to be changed less frequently, which reduces costs and maintenance time. Users of existing 58-liter cylinders will not need to purchase new gas regulators, as the 116-liter cylinders use the same regulators.
