Mississippi Operation to Fuel Kenworth Mixers with Modular PFS
TruStar Energy – formerly Vocational Energy – has introduced its new portable fueling system for compressed natural gas in Jackson, Miss., where the unit is supporting a new fleet of a dozen Kenworth concrete mixers operated by MMC Materials.
They are MMC’s first Kenworths, and they are powered by the new 11.9-liter ISX12 G dedicated-natural gas engine from Cummins Westport. MMC and an affiliate company have a total fleet of some 320 Mississippi mixers.
“Given the price difference between natural gas and diesel, it adds up quick,” MMC central region VP Stanley Mangum says in a TruStar announcement. MMC’s entire Jackson fleet will now operate on CNG, TruStar says.
66 DGE per Hour
The portable fueling system for MMC at Jackson can dispense 66 diesel gas equivalents of CNG per hour – adequate to fuel all 12 trucks overnight.
“We designed and built the PFS for exactly these types of fleets,” said TruStar Energy VP Scott Edelbach. “We knew that some fleet owners needed a portable fueling solution that offered compressor redundancy for reliability, but also a system that was appropriately sized for smaller operations.”
Twin Quincy Compressors
The PFS unit has twin 50-horsepower, 75-scfm Quincy compressors operating off of a 480-volt, 200-amp three-phase electrical service.
It comes standard with eight integrated time-fill hoses, expandable to 20 using additional fill posts.
The PFS measures 24 feet by eight by eight and requires a 20-foot by 30-foot site area for installation. It weighs 19,000 pounds. Hook-up takes just two to four hours at existing CNG stations or one to two weeks at new sites.
Edelbach said that the mobility of the PFS also makes it “a perfect choice” for fleets (like ready mix producers) that are distributed among several locations – a situation that makes traditional brick-and-mortar installations impractical.
