Engine coolant fluidspecifications
Never remove the cooling system
filler cap while the coolant fluid is
hot.
The system may be under pressure.
S l o w l y r e m o v e t h e c a p a n d o n l y
when the coolant fluid is at ambient
temperature. The sudden pressure
release, from a hot cooling system,
can make the coolant fluid splash
and harm somebody.
It is recommended the use of Atlas
Copco coolant fluids.
The use of the proper coolant fluid is very
important for a good heat transfer and protection
of engines cooled by coolant fluid. The coolant
fluids used in these engines shall be mixes of good
quality water (distilled or non ionized), special
coolant fluid additives and, if necessary, antifreeze
protection. The use of any coolant fluid that is not
recommended by the manufacturer, may cause
irreparable damages to the engine.
The coolant fluid freezing point shall be lower than
the freezing point of the area where the fluid is
used. The difference shall be at least 5°C. If the
coolant freezes, it may break the cylinder block,
the radiator or the coolant fluid pump.
Refer to the engineinstruction manual and observe
the manufacturer's instructions.
Never mix different coolant fluids
and mix the components out of the
cooling system.
PARCOOL EG specifications
PARCOOL EG is the only coolant fluid tested and
approved by all the manufacturers of engines
currently used in Atlas Copco generator sets.
The Atlas Copco long life PARCOOL EG coolant
fluid integrates the new range of organic coolant
fluids specially adapted forthe demands of modern
engines. PARCOOL EG may help to prevent
leakages caused by corrosion.PARCOOL EG is also
totally compatible with all types of seals and
gaskets developed to join the materials used inside
the engine.
PARCOOL EG is a ready-to-use coolant fluid based
on ethylene glycol pre-mixed in an excellent 50/
50 dilution rate, providing and antifreeze protection
warranty down to -40ºC.
Since PARCOOL EG prevents corrosion, the
formation of deposits is highly minimized. This
effectively eliminates the problem of an engine
coolant fluid, minimizing the risk of engine
overheatingand possible damages.
It reduces the wear of water pump seals and has an
excellent stability when subject to high running
temperatures.
PARCOOL EG does not have nitrides and amines
to protect health and environment.A longer service
reduces the engine coolantfluid amount, minimizing
the risk of engine overheating and possible damages
generated, and the need of disposal, thus minimizing
the environmental impact.
To ensure the protection against corrosion,
cavitation and formation of deposits, the additive
concentration in the coolant fluid shall be within
the limits established by the manufacturer. It is not
allowed to refill the coolant fluid only with water,
because this modifies the concentration.
The fluid cooled engine came filled from the
factory with this type of coolant fluid mix.
