This document discusses Ingersoll Rand's X4I System Controller product. It can control up to four compressors to optimize their operation and reduce energy costs. It allows compressors to run only as needed to meet demand rather than keeping extra units idle. It can also minimize wasted energy from keeping air pressure higher than necessary. The document provides examples showing potential energy and cost savings of up to 32% annually from more efficient compressor control and management of artificial demand.
