Balancing factor of rotary parts
On request rigid rotary parts by Neri are dynamically balanced per the standard ISO 1940, 1st part, grade G 6.3.

Tropicalization and condensation drainage holes (per CEI EN 60034-1 / IEC 34-1)
If the motors are installed outdoors or in high-humidity areas >60% (R.H.), the windings may be tropicalized upon request by cold painting with products having high water-repellent qualities, to protect the motor from condensation penetrating into the insulating materials and thereby avoiding damage to the insulating seal.
Also upon request, condensation drainage holes may be provided, closed with caps to be removed once the motor is installed.
