McNeilus, a U.S. manufacturer of refuse vehicles and ready-mixed concrete trucks, says it will exclusively use Luxfer G-Stor® Go Type 4 and G-Stor® Pro Type 3 carbon composite cylinders for its new NGEN Tailgate compressed natural gas (CNG) system for refuse trucks. “The tailgate system offers another lightweight option for refuse vehicles looking to utilize CNG for reducing fuel costs,” said Grant Wildgrube, senior project engineer at McNeilus. “It offers weight savings from the cylinders, and is easier to use and access.”
Available in 60-, 75-, 90- and 105-DGE (diesel gallon equivalent) capacities, the NGEN Tailgate system uses an exclusive, streamlined design with 50 percent fewer fitting connections and 25 percent fewer plumbing components. Two to four Luxfer cylinders are placed at the rear-end of the truck instead of on top, which reduces the overall height of the vehicle, eliminates the risk of tree branch or bridge impact to the system and offsets the weight of the front axle. A pressure-relief device (PRD) system spans the full length of the cylinders and provides continuous heat protection.
McNeilus Strike Protection, a sturdy steel covering, shields key CNG components. The system also features a unique pivoting structure that allows cylinders to be easily shifted, permitting more thorough inspections. Hydraulic tailgate props, designed for easier deployment and visibility from the cab, do not block access between the tailgate and truck body.
The 60-DGE model uses two 22- x 86-inch G-Stor Go tanks, and capacity can be easily increased up to 105-DGE—ideal when refuse collection routes change by season. McNeilus chose Luxfer cylinders because of their full range of sizes and significant weight savings to the system. “We like working with Luxfer because they’re open to co-development and always pursuing the next step in innovation,” Wildgrube said.
