Coolant additives

Cooling water NALCO CCL100
NOTICE
⇒ The only liquids or materials allowed to be used for cleaning and motor
cooling are those which do not corrode the motor cooling system and do not
react aggressively to the materials used in our motors.
⇒ Observe the instructions of the manufacturers of the cleaning agent and
the cooling system.
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.
Bosch Rexroth recommends using coolant additives of NALCO Deutschland
GmbH.
Depending on the size of the cooling system, the user may use different addi‐
tives in form of "ready-to-use cooling water" and "water treatment kits".
● Use of the following chemicals is designed for closed cooling
systems and the following metallurgy: Stainless steel, alumi‐
num, copper and non-ferrous metal.
● The container size and its ingredients of a water treatment
kit are adjusted for the specified system volume and can be
poured into the coolant tank without regard to other mixture
ratios.

Nalco CCL100 is a ready-to-use, preserved cooling water for the use in
closed cooling water systems. It is supplied directly to the closed systems
and contains all reagents in the proper treatment concentration.
Nalco CCL100 contains a corrosion inhibitor protecting ferrous metal, copper,
copper alloys and aluminum against corrosion. Nalco CCL100 is free of nitrite
and minimizes the micro-biological growth.
