Optimized Internal Diameters Make for Faster Fill Times
McNeilus Truck & Manufacturing is promoting enhancements to its compressed natural gas fuel system assemblies, citing a “portfolio of upgrades” that “improves performance and reliability through enhanced fill efficiency, plumbing optimization and best-in-class service and support.”
“McNeilus has engineered significant improvements to our already industry-leading Ngen CNG systems,” Brad Nelson, parent Oshkosh Corp senior VP and president of the firm’s commercial business segment, said in a release.
The Ngen fuel delivery system now features optimized internal diameters that offer up to 30% improved fill times. “The fill time now compares favorably to that of traditional diesel fuel,” McNeilus says.
Far Fewer Parts and Connections
Further, “Streamlining the design has reduced the number of plumbing components by 25% and the number of connections by a stunning 50%.”
Ngen systems also feature continuous protection thermal PRD/pressure relief devices throughout the length of the tank and system, increasing protection against localized thermal events. Typical PRD configurations contain more high pressure plumbing and have less thermal sensing surface, the company says.
For enhanced serviceability and reliability, McNeilus says, O-ring face seal fittings have been integrated, where possible. “ORFS fittings can be tightened to proper torque values, mitigating assembly/reassembly errors. They also offer superior rebuild ability over industry standard compression or flare fittings,” the company says.
New Vehicles or Upfits
Ngen CNG systems and services are available on new vehicles or customer-supplied vehicles as upfits through a national network of installation centers. They are backed by a two-year standard warranty. McNeilus carries a comprehensive inventory of replacement parts on hand at its regional installation centers.
“Through our national network of factory owned branches, our mobile technicians are certified to provide industry required three-year, 36,000-mile inspections,” Nelson said.
“We are in a unique position to deliver unmatched support for fleets of all types,” he said: “installation and support, with an extensive inventory of replacement parts and mobile service to deliver best-in-class value for our customers.”
