Explosion Proof Motors - EFF2 Improved Efficiency (Exd / Exde)
- Typical Applications
- The instalation of electric motors where flamable products are continuously handled, processed or storage, must comply with the most demanded safety standards in order to guarantee protection of life, machines and environment. Following to the highest safety standards WEG explosion proof motors integrate the high performance of the brakes. Perfect solution to equipments where fast safety stops are required, as well as precise positioning with safety in hazardous areas such Zone 1 and Zone 2. WEG Exd motors with brake are available in versions: Standard Efficiency (EFF2), Premium Efficiency (EFF1) and Top Premium Efficiency (Exceeds EFF1) and are certified to operate with frequency inverters.
