EcoPropel Variable Speed Pump

Pre-engineered and fully tested, Eco Propel integrates boiler firing rate with pump speeds improving boiler and system efficiency while reducing electrical consumption. Demand is calculated based on supply temperature, return temperature, and boiler firing rate determined from outdoor air sensor, header sensor, or set-point. A 0-10v signal is communicated to pump to harmonize this operation and ensure desired flow and constant delta T across all firing rates.
