Open the catalog to page 1

HYDROVAR, the modern variable speed pump drive is taking pumping to a new level of flexibility and efficiency.

Open the catalog to page 2

Motor or wall mountable More flexibility Cost savings High level hardware design Simple mounting ”clip & work” Multipump capability up to 8 pumps HYDROVAR is not only a simple to use speed control system for direct motor mounting. 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 system. Unique 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. This is the long-awaited...

RETROFITTING is possible on all existing standard asynchronous motors, which are suitable for VFD operation. Automatic adjustment of the pump performance to varying demands. Constant system pressure in water supply and booster stations. Possibility of control along the system curve for circulation pumps for the HVAC market. No external panels, contactors and motor protection devices are required. All hydraulic control functions are included in the HYDROVAR. Therefore no additional external controllers are required. Optimised cooling of the HYDROVAR, depending on the power and the speed of...

Clip & Work Especially in the operation at partial loads of a centrifugal pump there will be significant potential of energy savings! „TÜV-approved” Example: Circulation pump with nominal power in partial load operation. Power consumption as per curve Saving per 1/3 year (2.920 hours) Pump at constant speed Pump at variable speed Energy savings within 1 year (8.760 hours) Compared with the installation costs for the HYDROVAR units there will be a payback time of less than one year (depending of the energy costs).
