Luxfer-GTM for New CNG Fuelers
The Luxfer-GTM Technologies joint venture has mounted the first public display of new mobile fueling units for CNG. The GTM1350-R and G-Pak both employ aluminum-lined, G-Stor Pro brand Type III cylinders from Luxfer, packaged and plumbed by San Francisco-based GTM in Tulsa.
The GTM1350-R has a CNG capacity of 46,000 standard cubic feet of fuel, approximately 335 DGE (diesel gallon equivalents). It has an onboard booster pump and dispenser, all on a compact trailer that can be towed by a standard, three-quarter-ton pickup truck.
“There is nothing on the market today that can carry this much CNG behind a pickup truck while dispensing high pressure CNG,” said GTM Technologies president Michael Koonce.
The GTM1350-R is fitted with Luxfer’s proprietary glass-bulb PRDs. It has half-inch full-flow ball valves on each cylinder. The result is fast filling and fast discharging (as much as to 75,000 scf per hour) – “unmatched,” says GTM, by traditional steel or Type IV all-composite tube trailers.
The Luxfer-GTM G-Pak uses similar technology for a package that can be carried on a pickup truck. G-Pak variants are offered for both CNG and hydrogen fuel.
The CNG capacity of the G-Pak 3 is 21 DGE at 3,600 psi. Hydrogen capacity is 6.3 kilograms at 5,000 psi.
