Description

Principally the air oil cooler consists of a
cooler matrix, an AC-motor, a fan, a fan
housing and a fan guard. Depending on
electric motor size, the air oil cooler is
equipped with a motor bracket.
Different motor types are used on the
LAC-series of air oil cooler. Small
cooler fans are fitted with a single phase
or three phase outer-rotor motor. The fan
on larger air oil coolers is fitted with a
standard three phase asynchronous
inner-rotor, which meets the IEC 72 and
EN 60034 requirements.
The electrical motor should be connected
to the electricity supply system
according to instructions. See "Electrical
connection". Connect the cooler matrix
to the hydraulic system using hydraulic
hoses.
If the air oil cooler is fitted with a
thermo contact, the fan will start
automatically when the preset tempera-
ture has been reached.
Acoustic pressure could reach
50-90 dB(A) at 1 m distance depending
on air oil cooler size.
For information such as capacity,
nominal voltage and protection standard
etc., see marking sign on the motor.
Temperature for the electric motor:
-20 °C - +40 °C.
Refer to Technical specification for
maximum permitted static working
pressure, maximum permitted dynamic
pressure, maximum permitted fluid
temperature in the cooler matrix, etc.
