W21Xec – Increased Safety MOTORS
WEGINDO / PRODUCTS / ELECTRIC MOTORS / W21Xec (Increased Safety Motors)

The WEG W21Xec (Increased Safety) motor offers safety and reliability for operation in hazardous area classified as Zone 2 – Ex ec IIC T3, when an explosive atmosphere is not likely to occur in a normal operation or persist only for a short period.
Applications:
It offers safety and reliability for diverse applications within potentially explosive environments, such as in the oil & gas industry, marine environments, and other industrial processes where hazardous areas are present.
W21Xec Benefit:
- Complete range in IEC or NEMA standard.
- Low maintenance.
- High efficiency and reliability.
- Suitable for the use with frequency inverters.

WISE® WEG Insulation System Evolution
The WEG, WISE® insulation system (WEG Insulation System Evolution) has resulted from using enhanced insulation materials during the production of the electric motor insulation.
The WISE® (WEG Insulation System Evolution) is an advanced motor insulation technology developed by WEG to enhance performance, particularly in demanding applications such as those using Variable Frequency Drives (VFDs) or Variable Speed Drives (VSDs).
