Luxfer introduces new second generation Type 4 CNG cylinders

Luxfer Gas Cylinders will officially launch its second generation of G-Stor™ Go Type 4 carbon composite

cylinders for alternative fuel (AF) containment. Luxfer’s new GEN2 cylinders provide a 9% volume

increase of CNG in terms of diesel gallon equivalents (DGEs) and a 15% weight savings compared to the

company’s first-generation Type 4 AF cylinders. When compared to conventional competitive hybrid

carbon-fiberglass cylinders, the DGE volume improvement increases to 14% and the weight savings

grows to 30%.

Cylinder diameters from 22 inches to 27 inches are available; cylinder lengths range from 40 inches to

140 inches, the longest Type 4 fuel cylinder in the industry. GEN2 cylinders feature a new polymer liner

and patented boss design that provide the highest level of liner performance and gas retention.

Luxfer recently began shipping new GEN2 cylinders to its customers that serve the refuse truck, class-8

heavy-duty truck and medium-duty truck sectors. Mark Lawday, Luxfer’s alternative fuel business

development director, said: “We are excited that our long-term development and investment related to

our GEN2 range are complete and that we can now offer the extra volume and weight savings that our

customers need to optimize performance of their CNG systems. Feedback about these new products has

been very positive.”

GEN2 cylinders are equipped with Luxfer’s proprietary G-Flo™ valves that enable faster filling and

provide more usable gas. “The combination of our higher-volume, lighter-weight cylinders and our

unique valve technology should help relieve end-user ‘range anxiety’ about CNG-powered vehicles,”

added Lawday.
