CATERPILLAR COMPRESSOR CONTROLS

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.
