A module CNG refuelling system works for small back-to-base fleets.
MMC Materials Inc., has commenced deliveries of concrete with its newly acquired fleet of 12 Kenworth compressed natural gas (CNG)-powered concrete mixer trucks. Fueled by TruStar Energy’s portable fueling system (PFS), the mixers are said to be the first in the Southeast to run on the clean-burning domestic fuel and MMC Materials is among a small handful of ready mix producers throughout the US that have begun migrating to natural gas.
“We got real interested in this from an environmental standpoint and began looking at it over a year ago,” said Stanley Mangum, MMC Central Region VP, who said they also spoke with refuse haulers who were running CNG vehicles and felt confident that MMC was moving in the right direction.
MMC Materials is introducing their first Kenworth mixers, powered by the new Cummins-Westport ISX 12-liter CNG engine. With 320 mixers operating throughout Mississippi, Mangum sees a significant benefit. The CNG trucks will make up the entire fleet running out of Jackson, Mississippi.
MMC Materials purchased the modular TruStar Energy PFS to handle the fueling at their Jackson facility, where the trucks will be refueled overnight.
“We designed and built the PFS for exactly these types of fleets,” said TruStar Energy Vice President, 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.”
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 – making traditional ‘brick and mortar’ fueling stations less practical.
