Dynetek Buy Brings New Technology Options – Type IVs Planned
Luxfer Gas Cylinders will introduce an expanded line of aluminum-lined Type III CNG fuel cylinders at the Alternative Clean Transportation Expo in Washington, D.C. next week. Luxfer’s G-Stor Pro line takes advantage of process technology acquired with Canada’s Dynetek Industries last year.
Luxfer is also preparing a line of polymer-lined (and likewise carbon fiber wrapped) Type IV cylinders, confirms marketing manager Orion Goe.
Luxfer claims “the lightest-weight cylinders for containment of clean-burning, environmentally friendly compressed natural gas.”
The firm’s G-Stor Pro tanks range in capacity from 2.4 diesel gallon equivalents to more than 24 DGE at 3,600 psi. They are offered with outside diameters of up to 16 inches.
“These Type 3 cylinders are made with seamless, homogenous aluminum liners fully wrapped with high-strength, aerospace-grade carbon fiber,” Luxfer says. “The load-sharing liner provides an impermeable substructure for the wrapping, which creates an internal cylinder surface free from welds, joints and potential leak paths.
“Unlike permeable non-metallic, non-load-sharing liners, Luxfer aluminum liners present thermal dynamic characteristics that enable G-Stor Pro cylinders to be fast-filled – a significant productivity and cost benefit for busy vehicle fleets.
G-Stor Pro composite cylinders are 66% lighter than Type 1 all-metal steel cylinders. As such they offer fleet operators “improved fuel economy, increased range and significantly reduced vehicle maintenance costs due to lessened wear on brakes, tires and suspension systems.
“In haulage businesses, lower vehicle weights also allow higher payloads,” Luxfer says.
Dynetek Buy Brought Flow-Forming Liner Technology
Luxfer manufactures G-Stor Pro composite CNG cylinders at its main factory in Riverside, Calif., and at the facility in the Calgary formerly operated by Dynetek Industries. Besides bringing customers, the Dynetek acquisition brought a flow-forming, mandrel process for aluminum liner manufacture.
Luxfer acquired Dynetek in September 2012.
Luxfer Gas Cylinders further notes that with additional facilities in the England, France, Germany and China, it is the world’s largest manufacturer of aluminum and composite high-pressure cylinders, including its tanks for the storage and transportation of CNG, biomethane, hydrogen and industrial gases.
Luxfer composite cylinders are also used for medical oxygen, for breathing air for firefighters and other first responders, and for specialty electronic and calibration gases.
