Axial Flow Compressors

High Efficiency Axial Flow Compressors for High Volume Applications

Axial flow compressors are designed for high volume, high efficiency, and high reliability applications such as —

  • FCC air blowers
  • Blast furnaces
  • Air separation
  • Sewage treatment
  • Wind tunnels
  • Compressed Air Energy Storage (CAES)

The Dresser-Rand axial flow compressor line includes six standard frame sizes that are each available with three to 15 stages. Pressure ratio is determined by the number of stages. The required flow determines the frame size selected. The flow is further refined by tailoring the flow path (e.g., blade height etc.) to the specific requirements.

Available compressor upgrades and retrofits include —

  • Reinforced variable stator drive rings
  • Replacement of the pneumatic / hydraulic actuator system with a self-contained electro / hydraulic actuator
  • Variable stator inner hardware
  • Spring links
  • Rotor blade material upgrades
  • High head blade designs
