Efficiency Signal helps utilities, independent power producers, and plant owners keep steam surface condensers performing between outages, cutting fuel cost, derates, and emissions. Our CondenserSentinel solution models each condenser from its design records and existing historian data using HEI standards, then reports when performance is moving, where to look, and what to act on now. Nothing connects to the plant network. Field work is delivered with American Efficiency Services. We partner with service firms, instrumentation providers, and AWS Partners serving the power sector.
