In fact the HYDROVAR product represents an intelligent control system which accurately adapts the demand und offers plenty of advantages for both the operator and the modular design needs no additional master control and enables virtually any configuration of pumps: up to 8 master drives or a mix of master and slave drives.

2 This is the long-awaited solution for high-level installations requiring failsafe systems with a superior range of features, while its modularity also provides a cost-effective solution for low-level, reduced feature supplyOutput to motorTypeRated outputVoltage limits48-62 HzRecommended line protectionMax. voltage outputRated currentoutputHV[kW][V][A][V][A] ,51~220-240-10%+15%203~ , ,23~380-460 15%133~3 Uin5, , ,53~380-460 15%203~3 Uin13, , ~380-460 15%403~ , Data1,5 - 4 kW5,5 - 11 kW15 - 22 kWDimensionsThe new HYDROVAR concept allows optimum flexibility and en-sures cost savings not only during operation but also in purchasing and commissioningError Log with date and time stamp and included diagnostic menu to view temperature.

4 Which are suitable for VFD adjustment of the pump performance to varying system pressure in water supply and booster stations. Possibility of control along the system curve for circulation pumps for the HVAC external panels, contactors and motor protection devices are hydraulic control functions are included in the HYDROVAR . Therefore no additional external controllers are cooling of the HYDROVAR , depending on the power and the speed of the pump, is guaranteed by the motor maintenance intervals because of less stress to the pump and the brilliant mounting method of the HYDROVAR unit allows a very simple, fastand inexpensive retrofitting on existing in the operation at partial loads of a centrifugal pump there will be significant potential of energy savings!
