J-W Power Company Announces Patent of CNG Technology

October 03, 2017

Dallas, TX (Oct. 03, 2017)


J-W Power Company is pleased to announce the grant of U.S. Patent No. 9,765,930 B2 “CNG Fueling System” dated Sept 19, 2017.  This technology significantly improves compressed natural gas (CNG) fill time at the dispenser.

"We are proud of Rick Poorman and the rest of the CNG team for being awarded this patent.  Such an inventive yet practical solution is consistent with their work ethic and innovative nature, “stated James Barr, Vice President J-W Power Company. “If you are planning to build a CNG fueling station, J-W PowerFill Technology increases flow rates without increasing horsepower, significantly increases use of onsite storage, reduces starts and stops on equipment, and ultimately enhances the customer's fueling experience.  We designed and built a CNG compressor package that can decrease fill times significantly by maximizing your on-site fuel storage by allowing the compressor to change the number of stages dynamically to utilize high pressure from storage to yield a higher flow rate.”

This technology allows the compressor to change the number of stages dynamically to utilize high pressure from storage, which yields a higher flow rate. It is currently available in two models, J-W PowerFill and J-W PowerFill Lite. Both options are designed in a 4-stage/2-stage configuration. When filling storage, both package designs function in 4-stage mode. While a vehicle is fueling, the package automatically switches to 2-stages, increasing the flow rate up to 10x. Once the vehicle is full, the packages automatically switches back to 4-stage and fills storage.  With traditional technology, storage is typically 30% usable, with J-W PowerFill Technology, over 70% usage can be achieved!
