Over the years, TÜV has certified motors from numerous manufacturers, but this time, we managed to surprise them. We demonstrated that our motors were even better than what had already been certified:
✅ Minimal heating, even at reduced voltages, including on the rotor (which, for those unaware, heats up more than the stator!), thanks to very low power losses and a high service factor
✅ Optimal performance under inverter operation of any brand, and any Service Duty
✅ Superior IP protection rating
The result? A new ATEX certificate, bringing significant innovations:
- Still cool and safe, but now for higher ambient temperatures
- IE3 and IE4 ATEX motors, in their standard version, remain within the temperature limits for T4 gas class (135°C), but with dust surface temperatures lowered from 135°C to 120°C. Now, this is officially certified for use in environments up to +60°C.
- New T5 and T6 versions
- We introduce T5 (max 100°C) and T6 (max 85°C) versions, exceptionally cold motors, ideal for gases with extremely low ignition temperatures.
- Even lower surface temperatures
- The standard drops from 135°C to 120°C, with the option to further reduce it to 100°C and 85°C, making the motors safe even for the most hazardous dust environments.
- Maximum safety under all operating conditions
- The certification ensures that our ATEX motors maintain their safety in any duty cycle, from the classic S1 constant load to the demanding S9 service.
- Compatible with inverters from any brand
- Our motors maintain their safety not only with our inverters but also with third-party inverters, provided they meet specific technical requirements.
- Enhanced protection ratings
- Now also certified in IP66 and IP67 versions with resin-coated windings, for even greater reliability.
???? A step forward in safety, reliability, and performance in the ATEX world.
