5.5-Kilowatt Genset ‘Makes CNG Ideal for Small Service Trucks’
Cummins Onan is promoting as 5.5-kilowatt generator set as an auxiliary power unit for natural gas vehicles. The compressed natural gas-fueled Series 5500 NG generator set provides single-phase 120/240-volt electric power and optional hydraulic power for utility truck fleets, food trucks and other commercial vehicles running on CNG.
“This makes CNG ideal for the small service trucks used by telecommunications companies, utilities, food trucks and other commercial operations concerned with fuel economy and sustainable business practices,” states a release.
“These service fleets need auxiliary 120/240-volt power to run power drills, fans, pumps and other equipment, power which until now was available only from gasoline-powered generator sets that required a separate fuel tank.”
Targeting the Telcoms
The new Series 5500 NG is based on a line of compact and quiet generators for recreational vehicles, says Cummins Onan applications engineer Eric Bollensen. “We modified the time-tested engine to suit the needs of natural gas fuel properties while maintaining the engine’s proven performance,” he says in the product announcement.
Cummins Onan notes that in 2014 alone, AT&T and Verizon networks deployed more than 8,000 CNG vehicles in their fleets. The new APU is suitable for food trucks too, Bollensen told F&F, and even dog groomers. It has a small, 650cc spark-ignition engine.
Optional Hydraulic PTO
The new Cummins Onan generator provides instant power and is “recognized as the quietest and lowest vibration generator set in its class,” the manufacturer says. It features an enclosed muffler and exhaust catalysts helping it meet U.S. EPA and California air quality standards. The Series 5500 NG features self-diagnosis capability to simplify troubleshooting, and digital voltage regulation for voltage and frequency stability.
An optional hydraulic power takeoff unit can operate small cranes, splicing equipment and bucket hoists, while simultaneously providing electric power.
