Bosch Rexroth does not make any general statement and does
not conduct any surveys regarding the suitability of device-specif‐
ic cooling media, additives or operating conditions and does not
assume any warranty for third-party products.
The performance test for the used cooling media and the design
of the liquid cooling system is the responsibility of the machine
manufacturer. The selected coolant additives have to comply with
the materials within the cooling system.
Comply with the environmental protection and waste disposal in‐
structions at the place of installation when selecting the coolant
additives.
The proper chemical treatment of the closed water systems is precondition to
prevent corrosion, to maintain thermal transmission, and to minimize the
growth of bacteria in all parts of the system.
Coolant additives of NALCO Deutschland GmbH (example):
Coolant water Nalco CCL100 is a ready-to-use, preserved cooling water for
use in closed cooling water systems. Nalco CCL100 contains corrosion inhib‐
itor protecting ferrous metal, copper, copper alloys and aluminum. The water
is free from nitrite and minimizes the micro-biological growth.
Coolant additive NALCO TRAC100 is a liquid corrosion and film inhibitor for
the use in closed cooling systems. Nalco TRAC100 is a complete inhibitor
protecting ferrous metal, copper alloys and aluminum against corrosion. It is
free from nitrite and minimizes the micro-biological growth.
Coolant additive NALCO 7330 is a non-oxidizing broad band biocide and suit‐
able for application in closed cooling circuit systems.
Coolant additive Nalco 73199 is an organic corrosion inhibitor supporting a
fast own protection layer and covering protection layer for non-ferrous metals.
9.7.4 Materials used
At MBT motors, the coolant comes into contact with the following materials:
Frame size MST Cooling jacket Housing O-ring
130 ... 531
AlSi5Mg
-
Viton
360 ... 530 AlSi5Mg
Tab. 9-5: Materials coming into contact with the coolant
For dimensioning and operation of the cooling system, the machine manufac‐
turer has to ensure that the components of the motor do not get into contact
