The materials and protections with which we equip these machines ensure the correct functioning of the motors even in very severe temperature conditions.
We support you in choosing the configuration that best meets the characteristics of the installation in which these motors will operate.
The series name identifies the combination of materials of the main mechanical components of the engine (case and endshields):
