HYDAC Oil / Air Cooler Units Motor inverter series OK-EL MI
ATEX series
- For use in potentially explosive environments
- Also certified for a frequency of 60 Hz
The approval applies to use in areas (II) where an explosive atmosphere because of mixtures of air with gases, vapours or dusts is likely (2G/2D) and occasionally occurs in normal operation (Zone1/Zone21)
Motor inverter series OK-EL MI
With continuously variable speed control depending on the oil temperature at the cooler. The fan speed is thus directly adapted to the required cooling capacity.
Advantages:
- Constant operating temperature
- Low noise level
- Low energy consumption
