As a petrochemical company expanded to become the largest facility in the Middle East, Emotron drives were chosen for their durability, modular flexibility and service support.
Emotron high power VFDs built up with unique Power Electronic Building Blocks (PEBBs) were selected for the high pressure pumping system of the critical RO plant providing demineralised water for the plant processes, firefighting requirements and human needs.
In the first phase of the project a valve controlled membrane pressure system with pumps on fixed speed was chosen. This led to various problems:
As a result, a variable speed pumping system incorporating VFDs for motor speed control was chosen for the high pressure pumping system in the second phase of development.
Emotron high power VFDs are built up by combining power modules called PEBBs (Power Electronic Building Blocks).
Each PEBB is a complete VFD in itself comprising of input semiconductor fuses, rectifier, DC capacitors, chokes and inverter IGBTs – with only the control board missing. Multiple PEBBs are connected to a common control board and function as a single unit.
This makes it excellent for redundancy, scalability and ease of service.
The PEBB concept has been a highly valued characteristic in the petrochemical industry, securing operational efficiency at all times, due to:
