Orientation
For add-on equipment that cannot be cooled conventionally with cooling lubricants
or hydraulic fluid due to high temperature development, separate cooling is provided
in an independent cooling circuit. The coolant used here must be checked
continuously for its condition like other coolants.
Apart from this interval, the coolant should generally be replaced
once a year.
The system comprises a cooling circuit on the machine side and either
1. a water recooler located next to the machine or
2. an external cooling circuit provided by the machine operator/owner.
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!
For all work in connection with operating materials, the information in
the data sheets of the respective manufacturers and the information
in the document Notes on Operating Materials must be observed.
Requirement
Replenish only coolant of the same manufacturer having the same
specification. Mixing different coolants may lead to corrosion of the
cooling system, incompatibility and degradation of the coolant.
Required glycol concentration min. 34-35%.
When switching the coolant to another product or changing the
manufacturer, the cooling system must be completely flushed and
cleaned with this coolant. When preparing the coolant from
concentrate and water, be sure to use demineralized water only. Only
then the machine may be put back into operation.
Make sure that a concentration of FSK35 (35% glycol) is used in
machines 1-4. From Machine 5, a concentration of Antifrogen N (34%
glycol).
When using a water recooler, be sure to follow the manufacturer’s
instructions.
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!
