Coolant specifications
The use of the correct coolant is important for proper heat
transfer and protection of liquid-cooled engines. Coolants
used in these engines must be mixtures of good quality
water (distilled or de-ionised), special coolant additives
and anti-freeze, if required. Coolant that is not to
manufacturer's specification will result in mechanical
damage of the engine.
The freezing point of the coolant must be lower than the
freezing point that can occur in the area. The difference
must be at least 5 °C (9 °F). If the coolant freezes, it may
crack the cylinder block, radiator or coolant pump.
Consult the engine's operation manual and follow the
manufacturer's directions.
PARCOOL EG
PARCOOL EG is the only coolant that has been tested
and approved by all manufacturers of engines
currently used in Atlas Copco compressors and
generators.
Atlas Copco's PARCOOL EG extended life coolant is the
new range of organic coolants purpose-designed to meet
the needs of modern engines. PARCOOL EG can help
prevent leaks caused by corrosion. PARCOOL EG is also
fully compatible with all sealants and gasket types
developed to join different materials used within an
engine.
PARCOOL EG is a ready to use Ethylene Glycol based
coolant, premixed in an optimum 50/50 dilution ratio, for
antifreeze protection guaranteed to -40°C (-40°F).
Because PARCOOL EG inhibits corrosion, deposit
formation is minimized. This effectively eliminates flow
restriction problems through the engine coolant ducts and
the radiator, minimizing the risk of engine overheating and
possible failure.
It reduces water pump seal wear and has excellent stability
when subjected to sustained high operating temperatures.
PARCOOL EG is free of nitride and amines to protect
your health and the environment. Longer service life
reduces the amount of coolant produced and needing
disposal to minimise environmental impact.
Never remove the cooling system filler cap
while coolant is hot.
The system may be under pressure. Remove
the cap slowly and only when coolant is at
ambient temperature. A sudden release of
pressure from a heated cooling system can
result in personal injury from the splash of
hot coolant.
It is strongly recommended to use Atlas
Copco branded coolant.
Never mix different coolants and mix the
coolant components outside the cooling
system
PARCOOL EG
To ensure protection against corrosion, cavitation and formation of deposits, the concentration of the additives in the
coolant must be kept to certain limits, as stated by the manufacturer's guidelines. Topping up the coolant with water only,
changes the concentration and is therefore not allowed.
Liquid-cooled engines are factory-filled with this type of coolant mixture.
