In the United States alone, we use approximately 22 trillion cubic feet of natural gas per year. Just keeping up with this demand requires more than 300,000 miles of pipeline with over 40-million horsepower of compression capacity to operate. It’s a perfect environment for innovations from DDS. 

Compressor Drivers: Whether used as replacement components or as part of new infrastructure, DDS high speed electric motors provide cost-efficient, operationally superior and environmentally friendly drivers for compressor systems—less expensive in initial cost and far less expensive to maintain. The company’s driver offerings will be available in four standard ‘frame’ sizes, with operating powers ranging from 2MW to 28MW and speeds ranging from 22,500 rpm to 7,000 rpm. These offerings will be introduced to the market in stages. The first offering, a 2MW unit, the Frame 2, is already available with the Frame 8 to follow late in 2006.

Maintenance Costs: Ordinary electrical motors are mechanical systems that produce substantial friction, therefore, their bearings and oil lubrication system require ongoing maintenance. With a DDS motor, running on magnetic bearings and requiring no gearbox, these costs are avoided all together.

Life Cycle Costs: Because of the high operating efficiencies at full and partial loads, DDS motors make possible a system that can provide owners with the shortest payback period and lowest lifecycle cost—without sacrificing reliability.
