Momentum Fuel Technologies introduced two roof-mount configurations specially designed for the refuse industry to its line of compressed natural gas (CNG) fuel system solutions for Class 6-8 trucks.
“Our refuse customers continue to tell us they are interested in improved natural gas options, and the roof-mount system is designed to support the unique needs of this important market segment,” said W.M. “Rusty” Rush, Chairman, CEO and President, Rush Enterprises, Inc.
The roof-mount system is available in both four-tank 70 diesel gallon equivalent (DGE) and five-tank 87DGE configurations, and is designed to be a lighter and more efficient system when compared to industry standard 60DGE/75DGE roof-mount configurations.
The system is fabricated with high-strength steel and lightweight aluminum. The tanks are made of 3MTM nanoparticle-enhanced matrix resin technology and are designed to be lighter than others in the industry.
The system’s fuel management module (FMM) houses the electronics, fuel filter and fuel-fill receptacles and is conveniently located where the driver fuels the truck.
Constructed of highly-durable aircraft aluminum with a powder-coated exterior finish and Huck-bolted access cover, the compact design incorporates Parker O-ring fittings, gauges, fill ports and valves with a simplified filter access through the bottom of the module.
The FMM works in conjunction with the RushCare telematics platform, allowing fleet managers to monitor their usage stats and better manage their fuel consumption. Momentum’s roof-mount systems provide the industry’s best capacity by using tanks which are one-inch larger in diameter than competitive systems and hold more fuel in the same amount of system space as most existing designs.
Fuel utilization is improved due in part to an efficient fuel pressure regulator with a high-capacity filter manufactured by Parker, which is also part of the FMM.
With this regulator, drivers can go further on a tank of fuel when compared to current system limitations, as the regulator enables the vehicle to operate from 3,600 pounds per square inch (PSI) when full to a minimum 230 PSI.
The regulator is designed to reduce leak points and weight, and the high-capacity filter is larger than most competitive products, so it can be serviced less frequently.
The design of the nose of the roof-mount system incorporates three separate alloy steel pieces to protect the CNG system from tree limbs and other damage. If damage to the nose does occur, it is easier, safer and less expensive to repair or replace one or more segments rather, than the entire nose. The comprehensive pressure relief device (PRD) network vents fuel in the system out through vertical vents in case of fire or other emergency.
The PRD is engineered for rugged off-road use, safety, and durability and is fitted with weatherproof caps to protect the system from environmental elements. For safety conscious fleets, the PRD lines are coated in red to indicate to service personnel that the entire system must be completely purged before servicing the PRD system.
New and replacement parts for these systems are manufactured in-house by Momentum Fuel Technologies, ensuring quality and improving speed to customers.
The 70DGE and 87DGE roof-mount systems are in production for immediate delivery. Momentum Fuel Technologies offers the industry’s first complete CNG fuel system solution for Class 6 to Class 8 trucks, with comprehensive support from design and manufacturing, to sales and ongoing service throughout the product life cycle.
This product line was developed after thousands of hours of customer interviews and is focused on innovative design, advanced safety features, installation expertise and the industry’s most comprehensive support network.
In addition to the new roof-mount 70DGE and 87DGE products, Momentum offers side-mount systems in 30DGE, 40DGE, and 45DGE (all with or without the FMM) and back-of-cab systems in 70DGE, 75DGE, 115DGE, and 150DGE.
