“REP Holding” produces in series EGPU rated at 4, 6.3 and 12.5 MW. These units are designed for compression of natural gas at compressor stations and its transmission via gas-main pipelines. The Holding facilities produce directdrive oil-free units mounted on an active magnetic bearing, with dry gas-dynamic seals (DGS) and variable-frequency electric drive with a possibility of remote access.
The new generation EGPU are designed to replace the out-of-date electrically driven units during the reconstruction of the compressor stations.
Technical characteristics of the EGPU
- •natural gas centrifugal compressor;
•asynchronous high speed electric motor;
•semiconductor frequency converter;
•automatic control and governing system of the unit;
•gas air–cooler with a valve electric drive;
•active magnetic bearing system (AMBS);
•electric power supply system.
