Breuer frequency converter system solutions are used in all heavy duty industries such as oil & gas, mining, steel and cements industries as well as test bench technologies and special transportation equipment.

Our product line ecoVert® with its modular design and high power density makes it possible to offer an individual cost-effective solution to every customer. Drive concepts with ecoVert® are available in the power range 15 kW – 2700 kW for the voltage range 400 V – 1140 V. Due to DC-link connections it is possible to use external DC-power supply or to link various frequency converters. We can also supply any ecoVert® converter with internal PSU for single unit application or with central PSU (Power supply unit) for multi-drive solutions. Modularity enables high flexibility.

Our user interface is identical for all units and does not depend on power or voltage ratings. Its user-friendliness ensures quick installation and safe operation due to diagnostic tools as well as comprehensive protection concept. EcoVert® is symbol of quality, security and intelligent system solutions.
