Variable Frequency Drives & Controllers

HV 3.30 – 3.45 Hydrovar wall mounted pump controller 30-45 kW

Hydrovar; the intelligent variable speed pump controller

Hydrovar is the intelligent pump controller that matches the performance to the demand. The system consists of a variable speed drive (VSD), a control card, sensors, EMC filters and motor/system protection. There’s no need for an external control panel when using Hydrovar.

Energy savings potential

A motor running at 80% of its maximum speed uses 48% less energy. With energy savings of up to 70% on partial loads alone, the typical investment payback period is less than two years depending on energy costs and pump operating times.

Xylem offer a neat tool to calculate the potential energy savings using a VSD. Learn more about and download the Xylem Energy Savings Calculator here.
