Operation Data
Fluids Oils (mineral oils, synthetic oils, high viscosity oils,
biological oils, phosphate ester)
Water-glycol (cooling uid)
HFC pressure uids
Viscosity AC-LN: 2,000 mm²/s (standard)
ACA-LN / ACAF-LN: see technical data
Temperature range Minimum / maximum ambient temperature:
-20 °C to +40 °C (standard)
Minimum / maximum temperature of the medium: +130 °C
Please contact the technical sales department in the event of
deviating temperatures for applications with water-glycol.
Notice!
Fan switching frequency at max. fan 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 signicant
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.
Pressure resistance of the
cooling element
Dynamic operating pressure: 16 bar
Static operating pressure: 21 bar
Fan Axial fan in suction version (standard)
Axial fan in pushing version on request
(note: approx. 10 % less cooling capacity)

Other versions on request.
ErP The fan unit of the AC-LN corresponds to the minimum efciency
levels specied in the Ecodesign directive or ErP directive (Energy-
related Products) 2009/125/EC.
Pump
(only ACA-LN/ACAF-LN)
ACA-LN / ACAF-LN 2-3: screw pump
ACA-LN / ACAF-LN 4-5-6: vane pump
ACA-LN / ACAF-LN 7: screw pump with separate motor
Operating pressure:
max. 10 bar (screw pump)
max. 6 bar (vane pump)
Negative suction pressure of the pump: max. -0.4 bar
Pump motor speed: 3,000 rpm
Noise levels See technical data AC-LN and ACA-LN / ACAF-LN
The noise levels are only reference values as the acoustic properties
of a room, connections and reection have an effect on the noise
level.

General
The AC-LN 1-7 air cooler series can
be used in all areas where either oil or
water-glycol is to be cooled with air.
The coolers with an axial fan can be
used in the return line as well as in the
bypass ow.
The wide range of accessories and
optional versions mean that the coolers
can be adapted exibly to various
applications.
Product Features
The cooler can also be used in the
bypass ow by attaching a pump.
An additional lter enables continuous
ltration of the medium.
l Large product range
l Large cooling performance range
l Modular design

l Converters
l Machine tools
Options
Integrated pressure bypass valve
(IBP) / Integrated thermal pressure
bypass valve (IBT)
The bypass channel is integrated in the
cooling element. If a particular pressure
is exceeded, the IBP opens the bypass
channel, thereby protecting the cooling
element from too high a pressure.
Furthermore, the IBT only opens the
cooling element path once a particular
temperature has been reached.
ATEX
The AC-LN (without pump and lter)
is also available for operation in gas
and dust explosive areas. The ATEX
certication applies for a frequency of
50 Hz and 60 Hz.
Marine
The MAR version is for aggressive
ambient conditions, such as industrial
atmospheres, high humidity or high salt
content, which place great demands on
the corrosion resistance and robustness
of the materials used.
Cold Climate / Hot Climate
Use in extreme ambient conditions:
Cold Climate to -40 °C,
Hot Climate to +60 °C
The various versions can also be
combined. Our technical sales
department will be happy to assist
you further.

Cooling in bypass ow: ACA-LN / ACAF-LN
The ACA-LN with integrated boost pump is a complete bypass ow cooling system;
the ACAF-LN is equipped with a high-quality HYDAC lter for additional ltration.
Advantages:
l Stable cooling and ltration (independent of the cycle times of the system)
l Continuous ltration is possible, cooling as required
l Avoidance of pressure surges in the cooling element
l Design of the cooler is in accordance with the cooling capacity required
(not according to the maximum possible return ow volume)

Note:
We recommend maintaining a minimum
distance to ensure an unimpeded air
inlet and air outlet. This is half the
height of the cooling element (A/2).
Anything below the minimum distance
can inuence the cooling capacity and
the noise emissions.
