Frequency converters – the optimal drive for every application
Flow rates can be controlled far more precisely with variable-speed drive systems than they can using mechanical control concepts – and can be adapted to actual demand. The advantage: a significantly higher degree of reliability and quality for water supply and disposal systems. Further, variable-speed operation opens up enormous cost-saving potential of up to 50% and, in extreme cases, even up to 70% depending on the characteristic. This is the reason that a frequency converter often has a payback time of just a few months.
With SINAMICS, Siemens is offering an innovative family of drives that sets the standard in every respect in the range from 0.12 kW to 85 MW. In addition to a simple, standardized operator control philosophy, members of the SINAMICS family use the SIZER engineering tool for selecting and dimensioning, as well as STARTER for commissioning and diagnostics.
For applications in the water industry, many SINAMICS versions are equipped with functionalities specifically tailored to pump, fan, and compressor applications, such as SINAMICS G120P.
The MICROMASTER family of frequency converters addresses drive applications in the power range from 0.12 kW to 250 kW and distinguishes itself through its extremely easy handling – from installation, through commissioning, all the way to operation.
ROBICON Perfect Harmony rounds off our portfolio in the medium-voltage range. It is the undisputed No. 1 worldwide in medium-voltage frequency converters in terms of both market share and installed power. With this unit, low-voltage cells are connected in series, thus creating a medium-voltage converter that can be scaled very precisely for a wide voltage and power range. This unit is currently considered to be the most compact medium-voltage drive converter on the market.
