Standard series OK-EL
Our standard series oil-air cooler OK-EL is used to cool industrial hydraulic systems.
Different sizes and series and a wide range of accessories allow flexible adaptation to various applications.
OK-EL product features:
- Pressure resistance: 16 bar
- Cooling capacity up to 200 kW
greater cooling capacities possible as a special versions - Modular construction
OKA-EL and OKAF-EL series for bypass flow cooling
The OKA-EL version with an integrated pump is a complete bypass flow cooling system. The OKAF-EL is also equipped with a high-quality HYDAC filter.
Advantages:
- Stable cooling and filtration performance
independent of the cycle times of the hydraulic system - Avoidance of pressure surges in the cooling element
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
