Description
Variable Speed DrivesHydrovar – the modern variable speed pump drive is taking pumping to a new level of flexibility and efficiency
HYDROVAR® is not only a simple to use variable speed control system for direct motor mounting, it is an intelligent control system which accurately adapts to the demand and 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 an ideal 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 demands.
APPLICATIONS
- »  Constant pressure – residential, civil and commercial buildings
- »  Constant pressure – for boosting / transfer for irrigation and turf systems
- »  Constant temperature for heating and cooling applications
- »  Control of tank or reservoir levels with input from probes or a level transducer
- »  Flow control for when a constant flow rate is required against a varying system pressure
- »  Wall mount options to control submersible borehole pumps or remote applications
- FEATURES
- Motor or wall mountable
- More flexibility
- Cost savings
- High Level Hardware Design
- Easy to Commission
- Energy Savings up to 70%
- Simple Mounting “click and work”
- Multi pump Capability – up to 8 pumps

Advantages
The HYDROVAR® concept allows optimum flexibility and ensures cost savings not only during operation but also in purchasing and commissioning
East operation and programming due to the improved menu navigation and the backlight display – even in difficult to access installations
Error Log with date and time stamp and included diagnostic menu to view temperature, current and quality of power supply, facilitates diagnostics and failure analysis
Easy to integrate into building management systems with MODBUS interface included as standard
Integrated functions to protect pump, motor and the overall system
Easy assembly of multi pump systems up to 8 pumps without any external control units or other superior control systems
Greater redundancy and additional application possibilities like zone regulation with 2 connected actual value sensors
Integrated dry-run protection to shut-off the system in case of pipe burst
Extended manual control mode with either external as well as internal set points of different speed levels
RETROFITTING
Old unregulated pump systems work inefficiently. Regardless of the demand the pumps are always running at full speed, wasting energy. As the HYDROVAR® fits to all standard asynchronous motors, nearly all existing systems can be upgraded. No hydraulic changes are usually necessary. Due to its simple installation and big energy savings, a payback time of less than one year can often be achieved.
- Possible on all existing standard asynchronous motors, which are suitable for VSD 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 the pump, is guaranteed by the motor fan
- Longer maintenance intervals because of less stress to the pump and the motor
- The brilliant mounting method of the HYDROVAR® unit allows a very simple, fast and inexpensive retrofitting on existing pumps
Energy is the largest cost of running any pump, with the biggest potential savings. The HYDROVAR® works with your system
to make it efficient. This intelligent variable speed drive controls the pump exactly according to the current requirements of the customers.
Compared to an unregulated system, the HYDROVAR® saves up to 70% of the energy consumption (as tested by TÜV Austria, vogw0312-PIR-ZR). The smooth regulation at optimal operation increases not only the efficiency but also the life of the system’s components and reduces maintenance costs.
