Momentum Fuel Technologies, Roanoke, Texas, a Rush Enterprises company, has announced the addition of two refuse industry roof-mount configurations to its line of compressed natural gas (CNG) fuel system solutions for class six to class eight 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,” says W.M. “Rusty” Rush, chairman, CEO and president of Rush Enterprises Inc.

The steel and aluminum fabricated roof-mount system is available in both four-tank 70 diesel gallon equivalent (DGE) and five-tank 87 DGE configurations and is designed to be a lighter and more efficient system than industry standard configurations, according to Momentum. The tanks are made of 3M nanoparticle-enhanced matrix resin technology, the company says, making them lighter than competitors' tanks.

The system includes a fuel management module (FMM) that houses the electronics, fuel filter and fuel-fill receptacles. This works in conjunction with the RushCare telematics platform, allowing fleet managers to monitor their usage stats and fuel consumption.

The FMM also includes a fuel pressure regulator built by the Parker Corp., Cleveland, Ohio. This is designed to reduce leak points and weight and to allow drivers to go further on a tank of fuel, Momentum says.

“With the technologies built into our system, the usable capacity of these new roof-mount systems is a game changer,” says Mike Zimmerman, general manager, Momentum Fuel Technologies. “Our customers can now have the range of five tanks in a four-tank package.”

Momentum says it will work with McNeilus Truck and other truck manufacturers to ensure the line of Momentum CNG fuel systems is integrated with refuse bodies and other truck bodies.
