A 26.2-in. diameter cylinder has joined the company’s line of compressed natural gas tanks for heavy-duty trucks. First shown at the 2015 Alternative Clean Transportation Expo in Dallas, it is Worthington Industries’ largest Type III CNG cylinder and, product engineers contend, provides superior fast-fill efficiency. An inner aluminum liner dissipates heat during fast filling, affording an additional 15 to 25 percent more fuel storage compared to Type IV cylinders of similar size.
