Air Cooler Mobile OK-ELH 2-7 with hydraulic motor

Viscosity 2,000 mm²/s (standard)
Temperature range ll Minimum / maximum ambient temperature:
– 20 °C bis + 40 °C (standard)
ll Minimum / maximum temperature of the medium:
+ 20 °C to + 130 °C
Please contact the technical sales department in the event
of deviating temperatures.
Notice!
Fan at max. speed (max. volume of air) must be avoided when
operating a cooler at which the temperature difference between
the medium inlet at the cooler and the ambient temperature
can be greater than 50 °C. Quick changes in the temperature of
the cooling element material can lead to a significant reduction in
service life or to direct damage of the cooling element due to
thermal shock.
Please contact the technical sales department to receive
information about controlled fan drives.

Noise levels See technical data
The noise levels are only reference values as the acoustic
properties of a room, connections and reflection have an effect
on the noise level.
