Dresser-Rand Reciprocating Compressors

Dresser-Rand process reciprocating compressors are available with up to 10 crank throws, as single-throw or balanced-opposed configurations. We custom engineer every unit by designing each cylinder and valve, and select other components to meet your specific operating requirements. Our factory experts check all critical clearances and dimensions, and perform inspections and tests to prevent installation problems. The result is a reciprocating compressor that meets or exceeds client specifications, while delivering unmatched efficiency and reliability.

With the most versatile compressor lineup on the market and a reputation for serving standard applications and the most demanding jobs (high pressure, CO2, sour and acid gases, and floating applications), Siemens covers virtually every application. This class of reciprocating compressors is designed to meet ISO 13631 with options to meet ISO 13707, or API 618 specifications. Our offering includes six different models with horsepower (HP) ranges from 200 to 7,800 HP (5,816 kW), allowable rod loads from 15,400 to 75,000 PSI, rated maximum speeds from 850 to 1,800 RPM, and pressures up to 10,000 PSIG.

Most compressors produce more capacity than needed to allow for process control. The excess capacity is typically recycled to the inlet of the compressor to meet demand. The energy required to recycle the excess capacity is wasted.

Variable capacity control systems give operators the ability to adjust compressor capacity to demand eliminating recycle. This reduces energy usage and operating costs.

Variable capacity control devices are becoming more prevalent in the process market because of increased energy costs and the desire to save energy and related expenses whenever possible.

Valve performance and reliability is key to compressor performance. By paying careful attention to reliability in every aspect of the design, we’ve created a valve that can run more than 50 percent longer than other valves before needing service. We’ve proven it in thousands of hours of tests, many at high speeds and high temperatures, with a wide range of gases. Our engineers select the most appropriate valve based on their extensive experience as well as tools such as our Dynamic Valve Analysis (DVA) program.
