Electromechanical maintenance and repairs
Now more than ever, it's important that the company's mission revolves around the Client and his needs.
The main task of specialist maintenance consists in improving the components and machines and adapting them to the needs of the Customers, providing a redesign process where necessary. Moreover, we are able to offer a replacement of the components or machines if this choice is the optimal from both a technical and economical point of view.
The maintenance activity must be planned according to a preventive control plan. The purpose is to minimize any corrective actions, offering the customer a step-by-step monitoring control.
Thanks to its historical heritage, Misa has been able to develop specific skills and knowledge in the world of water pumping.
In addition, the continuous technical-engineering comparison with the Customers helps us develop products capable of optimizing the results, in the growing search for the efficiency of the plants and processes.

Maintenance of electrical substations

Maintenance of electrical substations must fully comply with current legislation.
The interventions are performed by highly qualified personnel (certified expert for work of installation and maintenance of electrical plants off voltage) in accordance with the current safety standards.
In addition to ordinary and extraordinary maintenance, our technical service is able to provide legislative and regulatory updates to the plants.

Strange encounters

During maintenance on the plants, small animals are often encountered, since they find shelter in the cabins or in the electrical panels, attracted by the heat during the winter.
Some of these (rodents, bees and reptiles) find refuge in the strangest places and sometimes fall victim to accidents, causing a blockage in the MV cabin or on LV switchboards and consequently to the plant.
Other animals have been rescued by our staff, making them return to their natural environment, or becoming the mascot of the plant.
