Dresser-Rand engineering heritage and global compression leadership
Operating as a premier turbomachinery brand within Siemens Energy, Dresser-Rand possesses over a century of proven innovation in high-pressure rotating and reciprocating compression technology.
Their equipment represents the worldwide benchmark for critical oil and gas production, pipeline transmission, LNG liquefaction, and petrochemical processing.
Dresser-Rand machines are purpose-built for continuous unspared duty on floating production storage and offloading (FPSO) vessels, harsh desert pipeline booster stations, and heavy refinery hydrocrackers.
Utilizing advanced alloy metallurgy, titanium components, and tungsten carbide coatings, the equipment provides outstanding operating longevity in severe sour gas environments containing corrosive hydrogen sulfide and carbon dioxide.
Modular bundle architecture of DATUM centrifugal compressors
The flagship DATUM centrifugal compressor line delivers unmatched operational flexibility through its innovative cartridge bundle concept.
The complete aerodynamic flow path assembly — comprising the precision-machined rotor shaft, 3D milled impellers, stage diaphragms, balance piston, and stationary labyrinth seals — is housed in a self-contained bundle.
During planned plant turnarounds or process rerates, the entire module can be unbolted and extracted from the horizontally split DATUM C or vertically split barrel DATUM P casing in a single shift, without disturbing process gas piping.
This cuts turnaround downtime from weeks to mere days while allowing aerodynamic retrofits to match evolving field reservoir pressures.
Heavy-duty reciprocating process compressors HOS and BDC
For critical hydrogen compression, hydrotreating, and hazardous synthesis gas services up to 700 bar, Dresser-Rand supplies heavy balanced-opposed reciprocating compressors under the HOS, HHE, and BDC designations.
Engineered in full compliance with API 618, their opposing throw configurations cancel out primary and secondary reciprocating inertia forces, eliminating severe frame vibrations even under driver ratings exceeding 30,000 kW.
Cylinders feature forged stainless steel bodies, hardened piston rods with specialized surface overlays, and self-lubricating non-metallic PEEK and PTFE piston rings, ensuring clean oil-free gas delivery for sensitive downstream catalyst beds.
Industrial steam turbines and Gimpel trip and throttle safety valves
Dresser-Rand steam turbomachinery (integrating the historic Terry, Coppus, Murray, and Worthington portfolios) delivers reliable mechanical drive for refinery feed pumps, compressors, and plant generators across broad industrial power envelopes.
Complete overspeed safety is guaranteed by genuine Gimpel Trip and Throttle Valves, which execute positive steam shutoff in less than 100 milliseconds upon trip signal activation, shielding high-speed rotors from catastrophic centrifugal destruction.
We provide genuine blading, nozzle segments, tilting pad thrust bearings, and certified Gimpel repair kits to maintain turbine integrity.
