Profile: Dresser-Rand specializes in offering turbomachinery products and control systems. Our datum C compressor is acceptable for onshore or offshore installation. Its small footprint and modular compressor bundle make installation and maintenance easier than conventional units, while minimizing the requirements for auxiliary systems and buildings. Our axial flow compressors are designed for high volume, high efficiency and high reliability applications. These applications include air separation, sewage treatment, wind tunnels and CAES. Two of our primary applications are FCC air blowers and blast furnaces. Our axial-flow compressor line includes six standard frame sizes that are each available with 3 to 15 stages. Pressure ratio is determined by the number of stages and flow is varied by changing the length of the blades.
