Derek Camp, Director of Engineering
“Most often, liquid cylinders are used to provide gaseous delivery in a smaller container by storing a liquid and vaporizing within the container to provide the intended gas pressure. Additionally, liquid cylinders can supply product in their liquid state. In many cases, customers utilizing high-pressure gases can graduate from liquid cylinders to MicroBulk or bulk-supplied products. Liquid cylinders allow for less cylinder change-outs on conventional cylinder and manifold configurations.”
