The specialist for pumps and fans

Pumps, fans are often controlled based on traditional and tried and tested control procedures. A decisive disadvantage: The motor is constantly running at rated speed with maximum flow rate – although this is rarely required in practice.
The result: continuous operation with a high power loss, e. g. throttle control. In variable-speed operation with a frequency drive, however, a great amount of energy can be saved.
Frequency drives saves additionally by adapting to the optimum operating point. Variable-speed drives depend on the type of driven machine. This is where optimized machines for as pumps, fans or compressors show their “economical side”.

Every task performed by a drive system involves its own specific requirements. There is therefore a demand for inverter solutions that can be easi- ly and flexibly adapted to cope with the broadest variety of challenges. It is exactly this flexibility which characterizes our modular MICROMAS- TER 430. Specially for use with pumps and fans in industry, it performs a wide variety of tasks in similar applications as well. Compared to the MICROMASTER 420, it features greater power efficiency and has more inputs and outputs as well as an optimized operator panel with switch- over between manual and automatic modes of operation.

Typical uses

Specially suitable for pumps and fans.
