Applications
Midimaster Eco drives are used in pump and fan applications requiring variable speed control. This unit was pulled from a boiler fan motor application. Commonly deployed in HVAC systems, industrial ventilation, and process cooling where soft-start and speed regulation reduce energy consumption and mechanical stress.
Condition: Used
This Siemens Midimaster Eco 6SE9525-4CJ50 frequency inverter has been inspected and appears to be in good condition. It was pulled from a working environment — the front panel label identifies its prior application as a boiler fan motor frequency controller. The enclosure shows typical light surface wear consistent with industrial use; a small stain is visible on the lower right side of the front door. The interior drive chassis, capacitor bank, control board, and integrated EMC filter (B84143-A96-R38) all appear intact with no visible damage. Please view our photo set and contact us if you have any questions.
