Armstrong Limited has extended the range of Intelligent Variable Speed (IVS) and IVS Sensorless pumps with integrated controls. The IVS and IVS Sensorless offerings are now available with integrated controls to 75hp on series 4300-IVS and 4302-IVS dualARM vertical in-line pumps. Separate stand-alone controls are available for larger IVS units and for a number of commercial pumps. Adding the Sensorless option also saves building owners the cost of installing, commissioning and maintaining remote-mounted sensors. The IVS Sensorless uses patented software technology to sense changes in building load and adjusts speed to meet demand.
