The Intelligent Variable Speed Sensorless Pump - or IVS Sensorless - is comprised of a pump-mounted VFD & integrated controller that reduces mechanical room footprint and simplifies installation while it guarantees efficiency optimization without remote sensors. The IVS is piped up, electricity plugged in and it matches system demand perfectly - without remote sensors. All the benefits of variable speed pumping with unmatched energy savings at less cost and less risk.

This is what the IVS Sensorless eliminates:
• Remotely mounted DP sensor
• Wiring from the DP sensor to the VFD and/or BMS and THEN to the VFD
• Wiring from the VFD to the pump
• Floor space for the remotely mounted VFD with our integrated VFD
• Sensor positioning errors and lost energy savings
