Old design of Mecc Alte ECO40 B type


When compare with Mecc Alte ECO40 C type, the old design of the Mecc Alte ECO40 B type series, the design overview is in a closed framework, the keys are tightly welded to create rigidity and not flexible, showing strong in appearance but general model creates a weak point in the maintenance, servicing and inspection of the AVR as well as the inspection of the core copper wiring in the Mecc Alte generator.

Although the capacity and performance do not affect much, it affects a small part of the maintenance and inspection stages in the technician’s work, the opening and screwing operations take a lot of time. Even with long-term use, the smallest points are oxidized, making it difficult to open and close the inspection. More specifically, when performing maintenance, checking the AVR or the components in the player box will cause wear and tear of components, reduce protection as well as reduce the ability to stabilize the optimal maintenance performance of the device: Mecc Alte alternator.
