The SINAMICS PERFECT HARMONY GH180 is a series of cells linked together to create the medium voltage power output of the drive system. The design features an integrated transformer and the ability to scale the drive for a wide range of voltage and output power. The drive offers increased availability due to its modular design and ability to bypass any one cell during operation. The quality of the output voltage is so close to perfect sine-wave shape that motors of literally any type – old or new, low-speed or high-speed – can be operated without any additional stress.

Commonly found on pumps, fans and compressors in the Oil & Gas industry. Capable of supporting electrical submersible pumps (ESP) and other long cable applications, as well as supporting LNG and high speed applications.
Frequently used in medium voltage pump, fan, and compressor applications. Also able to supports mixers and extruders in the chemical and petrochemical industries.
Used in numerous pump and fan applications in the power generation industry, such as ID Fans, FD Fans, coolant pumps and boiler feed pumps. Our water-cooled drive is the only converter approved for use on nuclear power plants due to its high availability and redundant operational components.
Utilized in several mining applications such as slurry pumps, uphill conveyors, crushers, vertical mills, VertiMills, select horizontal mills and standard mining pumps and fans.
Able to support applications such as vertical mills, crushers, kiln drives and standard cement fans and blowers.
Commonly supports metals applications such as basic rolling mills, sinter fans, de-dusting fans, de-scaling pumps, and other standard pumps and fans.
Within the water and wastewater industry this drive will mainly support pumps and fans in the several different types of water plants such as desalination, drinking water and wastewater, as well as assisting with water transport & pipeline networks.
Capable of supporting most medium voltage drive system retrofit projects, for applications such as pumps, fans, and compressors.
The new medium-voltage converters allow for speed-controlled operation of fans and eliminate the previously used damper for flow control.
