The Professional Choice
LHC
With hydraulic motor
OLAER LHC | optimized for mobile and industrial use
The LHC air oil cooler with hydraulic motor is optimized
for use in the mobile and industrial sector. Together
with a wide range of accessories, the LHC cooler is
suitable for installation in most applications and
environments. The maximum cooling capacity is 160 kW
at ETD 40 °C. Choosing the right cooler requires precise
sizing. The most reliable way to size is with the aid
of our calculation program. This program, together
with precise evaluations from our experienced, skilled
engineers, gives you the opportunity for more cooling
per € invested.
Overheating - an expensive problem
An under-sized cooling capacity produces a temperature
balance that is too high. The consequences are poor
lubricating properties, internal leakage, a higher risk
of cavitation, damaged components, etc. Overheating
leads to a significant drop in cost-efficiency and
environmental consideration.
Temperature optimisation - a basic prerequisite
for cost-efficient operation
Temperature balance in a hydraulic system occurs when
the cooler can cool down the energy input that the
system does not consume - the system’s lost energy
(Ploss = Pcool = Pin – Pused).
Temperature optimisation means that temperature
balance occurs at the system’s ideal working
temperature – the temperature at which the oil’s
viscosity and the air content comply with recommended
values. The correct working temperature produces a
number of economic and environmental benefits:
• The hydraulic system’s useful life is extended.
• The oil’s useful life is extended.
• The hydraulic system’s availability increases –
more operating time and fewer shutdowns.
• Service and repair costs are reduced.
• High efficiency level maintained in continuous
operation – the system’s efficiency falls if the
temperature exceeds the ideal working
temperature.

Optimal sizing produces efficient cooling. Correct sizing
requires knowledge and experience. Our calculation
program, combined with our engineers’ support, gives
you access to this very knowledge and experience. The
result is more cooling per € invested.

Valuable system review into the bargain
A more wide-ranging review of the hydraulic system is
often a natural element of cooling calculations. Other
potential system improvements can then be discussed
– e.g. filtering, offline or online cooling, etc. Contact us
for further guidance and information.
OLAER’s quality and performance guarantee
insurance for your operations and systems
A constant striving towards
more cost-efficient and environ-
ment friendly hydraulic systems
requires continuous develop-
ment. Areas where we are
continuously seeking to
improve performance include
cooling capacity, noise level,
pressure drop and fatigue.
Meticulous quality and performance tests are conducted
in our laboratory. All tests and measurements take
place in accordance with standardised methods -
cooling capacity in accordance with EN1048, noise
level ISO 3743, pressure drop EN 1048 and fatigue ISO
10771-1.
For more information about our standardised tests, ask
for “OLAER’s blue book – a manual for more reliable
cooler purchasing”.

With our specialist expertise, industry knowledge and advanced technology,
we can offer a range of different solutions for coolers and accessories to meet your requirements.
Supplementing a hydraulic system with a cooler, cooler accessories and an accumulator gives you increased availability
and a longer useful life, as well as lower service and repair costs. All applications and operating environments are unique.
A well-planned choice of the following accessories can thus further improve your hydraulic system. Please contact
Olaer for guidance and information.
Take the next step
- choose the right accessories
Pressure-controlled
bypass valve Integrated
Allows the oil to bypass the cooler matrix if the
pressure drop is too high. Reduces the risk of
the cooler bursting, e.g. in connection with
cold starts and temporary peaks in pressure
or flow. Available for single-pass or two-pass
matrix design.
Temperature-controlled
bypass valve Integrated
Same function as the pressure-controlled
by–pass valve, but with a temperature-controlled
opening pressure - the hotter the oil, the
higher the opening pressure. Available for
single-pass or two-pass matrix design.
Thermo contact
Sensor with fixed set point. For temperature
warnings, and for more cost-efficient operation
and better environmental consideration through
the automatic switching on and off of the
fan motor.
Stone guard/Dust guard
Protects components and systems from
tough conditions.
Lifting eyes
For simple installation and relocation.
Temperature-controlled
3-way valve External
Same function as the temperature-controlled
bypass valve, but positioned externally.
Note: must be ordered separately.
