Lowara 5th Generation Hydrovar Inverter Variable Speed Drives
Lowara 5th Generation Hydrovar Inverter Range
Frequency invertor attatched to pumps to change speed and to give constant pressure control.
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.
The Hydrovar is easily mounted directly on the motor of the pump and will fit on any standard IEC motor.
This makes the Hydrovar an excellent choice for retrofitting and upgrading of fixed speed systems.
Easy to Commission
The quick start up guide and logic menu system makes the Hydrovar easy to set up and operate.
Advanced programming features allow optimizing the Hydrovar for almost any duty condition.
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 please contact our
