Compact Integral Electric Motor Driven Compressor
For clients concerned about installation costs, reliable performance, and environmental issues, the following features make the DATUM C compressor an excellent choice for pipeline service:
- Integrated, high-speed electric induction motor manufactured by Curtiss Wright EMD
- Available in single-stage overhung and multi-stage beam-style configurations
- Natural gas cooled or hydrogen cooled motor
- In-line piping flanges for single stage compressor configurations
- Variable-speed operation
- Hermetically sealed
- Magnetic bearings for compressor and motor
Easy To Install And Maintain
The 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.
Environmentally Friendly
Because of its integrated and totally enclosed configuration, the DATUM C compressor offers significant environmental benefits. One of the most significant design features of the DATUM C compressor is the use of magnetic bearings. The unique application of magnetic bearings in the DATUM C compressor uses digital – instead of analog – controls, computer-based algorithms make tuning and adjusting the bearings very simple and efficient. Because of the magnetic bearings there is no need for an oil lubrication system. Some significant environmental benefits include the following:
- Emission-free design
- Quiet operation
- Reduced footprint
- No on-site leakage from shaft seals
- Magnetic bearings that eliminate need for oil lubrication
- Unit can remain pressurized during shutdowns, reducing start-up time
