Air Cooler Industry OK-ELC 0-7

Fluids Oils (mineral oils, synthetic oils, high viscosity oils,
biological oils, phosphate ester)
Water-glycol (cooling fluid)
Viscosity 2,000 mm²/s (standard)
Temperature range ll Minimum / maximum ambient temperature:
– 20 °C to + 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.

Other versions on request.
ErP The fan unit of the OK-ELC corresponds to the minimum efficiency
levels specified in the Ecodesign directive or ErP directive
(Energy-related Products) 2009/125/EC.
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.
Accessories ll Integrated pressure bypass valve (IBP) or
integrated thermal pressure bypass valve (IBT)
(cannot be retrofitted, also see options)
ll Thermostats
ll Air filter grid or air filter mat
ll Vibration damper…
