constructing and operating cooling systems.
⇒ Do not use any lubricants or cutting materials from
operating processes.
All information and technical data are based on water as the coolant. If
other coolants are used, these data no longer apply and must be
recalculated.
A cooling with floating water from the supply network is not
recommended. Calcareous water can cause deposits or corrosion and
damage the motor and the cooling system.
For corrosion protection and for chemical stabilization, the cooling water
must have an additional additive which is suitable for mixed-installations
with the materials acc. to Fig. 9-16.
The utilization of aggressive coolants, additives, or cooling lubricants can
cause irreparable motor damages.
⇒ Use systems with a closed circulation and a fine filter ≤ 100 µm.
⇒ Heed the environmental protection and waste disposal instructions at
the place of installation when selecting the coolant.
Aqueous solutions ensure reliable corrosion protection without significant
changes of the physical property of the water. The recommended
additives contain no materials harmful to water.
Corrosion protection oils for coolant systems contain emulsifiers which
ensure a fine distribution of the oil in the water. The oily components of
the emulsion protect the metal surfaces of the coolant duct against
corrosion and cavitation. Herewith, an oil content of 0.5 – 2 volume
percent has proved itself.
Does the corrosion protection oil compared with the corrosion protection
has also the coolant pumping lubricant, then the oil content of 5 volume
percent is necessary.
⇒ Heed the instructions of the pumping manufacturer!
