J-W Power Company History 

   Howard Westermans involvement with gas pipelines and fascination of mechanical equipment led to his interest in gas compressors. J-W Power Company was officially formed August 19, 1988, but was leasing compressor packages purchased from third parties as far back as October 1966 under the parent companys name of J-W Operating Company.  ​  The majority of this early equipment was slow-speed integral compressors manufactured by Ajax. When Ariel Corporation began manufacturing high-speed separable compressors, J-W Power Company was one of the early packagers with Ariel becoming the mainstay of the current lease fleet.  ​  J-W Power Company fabricated its first compressor package, an Ariel JGM/2 compressor driven by a Witte engine rated 18 BHP @ 1400 RPM, in May 1976 in a small shop in Longview, TX. Needing a place to test his ideas for improving gas compressor packages, Mr. Westerman constructed a larger plant on the outskirts of Longview, TX in January 1978 which is still in operation today.  ​  Since that time J-W Power Company has been an innovator in gas compressor package design, currently holding many patents and trademarks. J-W Power Company actually packaged some of the industrys first oil-flooded rotary screws in December 1978 and in October of 1986 patented a two-stroke stratified engine later known as the Superburn®.  ​  J-W Power Company has expanded primarily through organic growth with a few strategic acquisitions in core areas since buying that first compressor. J-W Power Company is currently considered an industry leader in leasing, service, fabrication and sales of natural gas compression equipment.     J-W Power Company is currently the largest privately-owned compression packager and is considered one of the premier manufacturers of packaged gas compressors while providing some of the best maintenance service in the industry.

Compressed Natural Gas (CNG) 

​  J-W Power Company has been involved in natural gas compression since 1966 and currently operates the largest privately-owned compression leasing fleet in the United States.  Over time, J-W built a solid reputation for manufacturing effective, durable, and reliable compression equipment.  ​  Building over 4,000 compressor packages over a forty year span naturally led J-W Power Company to be an authority in highly-engineered compressor package design, such as the equipment used in compressed natural gas (CNG) applications.       J-W Power Company built its first compressor package designed specifically for a CNG application in March 1994 and has manufactured over 73,000 horsepower of CNG packages since that time.  ​  J-W Power Company compressed natural gas packages are available for sale, with or without maintenance. We can provide our customers with station equipment installation assistance and contract maintenance services.

Horsepower Calculator â€‹

The following calculation method uses the Gas Processors Suppliers Association Engineering Data Book Eleventh Edition, FPS Version, 1998, eq 13-4 developed for large slow speed (300-450 RPM) compressors with SG = 0.65 and having CR > 2.50. Discharge temperature based on eq 13-18 assuming 130 Deg F inlet and k of 1.3  ​  Brake Horsepower = 22 * (ratio/stage) * (Number of Stages) * ( MMSCFD) * (F) where F = 1.0 for a single stage, 1.08 for a two-stage and 1.1 for a three-stage.
