Through its joint venture with GTM Technologies, the company announced it will introduce the mobile GTM1350-Refueler for dispensing high-pressure CNG, plus the G-Pak system for storage and transportation of high-pressure gases, including CNG and hydrogen, at pressures up to 5,000 psig. The launching will take place this week at ACT Expo 2014.
Mounted on a compact trailer that can be towed behind a standard 3/4-ton pickup truck, the GTM1350-R has a CNG capacity of 46,000 SCF (335 DGE) and an integrated, on-board booster pump and dispenser. For CNG storage, it uses Luxfer G-Stor® Pro Type 3 carbon composite cylinders, a glass-bulb pressure-relief device (PRD) system and 1/2-inch full-flow ball valves on each cylinder. The total gross weight is only 9,150 pounds.
The pump can be powered either by outside compressed air (100 psig) or from pneumatic energy stored in an isolated group of cylinders within the trailer, providing users the ability to fill vehicles without the need for external power. It is ideal for supporting remote fleets and other applications requiring mobile CNG. Standard equipment includes both NGV1 and NGV2 filling receptacles mounted in a separate panel so that customers can easily refill the trailer at conventional CNG filling stations.
At the heart of the G-Pak system are Luxfer G-Stor® Pro Type 3 (aluminum-lined) carbon composite cylinders fitted with high-flow valves and protected by a reliable glass-bulb-based pressure/thermal safety system. It consists of an all-aluminum frame that encloses the cylinders, a regulated control panel, a high-flow regulator, easy-to-use push-pull valve actuators and built-in NGV1 receptacles that allow the G-Pak to be filled at most CNG stations. Customized control panels are also available.
An important G-Pak feature is its small footprint, which enables two or three units to be stacked in the bed of a standard pickup truck. Two units have a tare weight of only 520 pounds, so one or two G-Paks with CNG can be transported without a driver’s hazmat endorsement or truck placarding. CNG capacity is 21 dge at 3,600 psig, while hydrogen capacity is 6.3 kg at 5,000 psig.
