产品特点 Intellgent, complete variable speed pump controller Motor- or wall mounted Easy to commission Multi pump capability from 1 - 8 pumps Main control offerings:
Constant pressure Constant flow According to system curve Via an 4-20 mA or 0-10 V external signal
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.
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.
