COOL-CORE FLUID is used as an anti-corrosion additive in motor spindle cooling systems. The substances it contains passivate the various materials and provide long-term protection against corrosion.

Technical details

Nice to know


  • Prevents electrochemical corrosion
  • Protects aluminium, ferrous and non-ferrous metals
  • Low-maintenance
  • Long-term protection
  • Frost-resisting to -30°C


Only drinking water is acceptable for use when preparing COOL-CORE FLUID as this water must not exceed the following limits:

- Water hardness max.3.6 mmol/l
- Chloride max.100 ppm
- Sulphate max.100 ppm

Prepare COOL CORE coolant mixture with 30% COOL CORE FLUID and 70% drinking water. Only use clean containers for preparing the mixture. Pour the mixture into the prepared cooling system immediately.
If the given water properties are not met COOL-CORE READY must be used.
If the coolant is used under optimal operating conditions while proper maintenance has been performed according to the instructions the coolant's service life may be up to 4 years.

Important: Galvanised components or similar materials must not be used either in the cooling system or in the mixing or storage containers.
An average operating temperature of 20-25°C will provide very effective long-term protection for elastomers.
