Anti-condensation heater (per CEI EN 60034-1 / IEC 34-1)
In applications where the ambient temperature is extremely low (0°C) or where the humidity is high (> 60% R.H.), it is possible to install a special pre-heating element on the winding heads for the machine when not running.
This prevents mechanical parts such as bearings or isolations from being damaged by low temperatures.
The heating power of the heater depends on the motor size; AC supply voltages upon request.
The terminals are free or fixed to the terminal board upon request.

Power cooling
For applications with a rated torque below motor speed at 50 Hz, the appropriate power cooling must be mounted as there are too many variables involved to determine the various possible thermal duties, and thus the temperatures reached by the motors.
