Specialty Controls for Air Compressors
A general description of this category of projects.
Matrix Engineering has designed several Modicon PLC based controls packages for FS Elliot compressors. These designs include load sharing, sequencing, and anti-surge control. These projects included both electric motor as well as steam turbine driven units. These units served foundries as well as refineries both domestic and abroad.
Matrix provides electrical engineering services in the design of systems to control and monitor Ingersoll-Rand CENTAC compressors. These systems consist of a variety of PLC manufacturers and graphical operator interfaces to provide a retrofit to their now obsolete Westinghouse MP3 controller as well as an alternative to the current proprietary controller used by Ingersoll-Rand.
Matrix Engineering provided PLC programming and HMI configuration for a Modicon based control system for two FS-Elliot compressors at a refinery upgrader for oil sands in Fort Saskatchewan, AB Canada.
Matrix Engineering completely designed a replacement control system for two existing IR CENTAC compressors. This was the main compressed air supply to their foundry. Both compressors were 4 stage 1500 HP units. This controls system utilized one main PLC with a "hot stand-by" PLC back-up. We were able to monitor the main plant compressed air flow as well as the blow-off air to economize the compressors and minimize wasted air. This is a massive energy saver and is a control feature not offered by Ingersoll-Rand and as far as we know, the only installation of its kind. This project was so successful that we have since returned and added more units to the control scheme as the compressed air system was expanded.
