Specification of coolants
Coolant is a noxious fluid.
Protect skin and eyes.
Coolant is harmful for the environment; after use,
it should be processed as industrial waste.
The cooling system should preferably be filled with a ready-mixed
coolant containing antifreeze and corrosion-inhibiting additives.
When tap water is used, an ethylene-glycol based antifreeze must
always be added as well as corrosion-inhibiting additives if there is
a possibility of the ambient temperature falling below +5°C.
- For protection down to - 18°C, a solution containing 33%
antifreeze can be used.
- For protection down to - 37°C, a solution containing 50%
antifreeze can be used.
Both ANTIFREEZE and ANTI-CORROSION coolants must
satisfy the following specifications:
ethylene-glycerol: ASTM D-3306, BS 6580 and SAE-J-1034;
propylene-glycerol: ASTM D-5216 and BS 6580.
Ethylene-glycerol and propylene-glycerol must never be mixed
because the agents cannot tolerate each other. It is also better not
to mix one type of glycol coming from different manufacturers.
In the summer, coolant containing antifreeze can remain in the
cooling system.
The antifreeze concentration, and the protection taken, for example,
against corrosion, should then also be kept topped up.
In climates where temperatures never fall below + 5°C, it is sufficient
to add a corrosion-inhibiting agent to the coolant according to ASTM
D-3306.
Follow the manufacturer’s instructions when using coolants.
Coolant quality requirements:
- pH 5.5-9.0
- total solid matter ≤ 340 ppm
- Hardness ≤ 170 ppm (calcium and/or
magnesium carbonate).
- Chloride ≤ 40 ppm (sodium chloride)
- Sulphate ≤ 100 ppm (magnesium
and/or sodiumsulphate)
In regard to the use of additives, the cooling system should be
flushed out and filled with the new coolant every two years.
The information and data given above are based on normal
operating conditions. As the specified substances are marketed
under various brand names, consult your lubricant supplier for the
correct interpretation of these specifications.
