MOTOREX COOL CONCENTRATE is a fully synthetic, water-miscible coolant concentrate. Its ingredients passivate the various materials used in a closed cooling circuit and provide protection against corrosion*. Mixed COOL-CONCENTRATE is a very efficient coolant with a specific heat of 4.1 J/g-K, which is virtually the same value as for water (4.187 J/g-K).

Characteristics

• Ready to use
• Very efficient
• Heat dissipation
• Prevents electrochemical corrosion
• Effectively protects aluminum, nonferrous and ferrous metals against corrosion
• Galvanized parts are not attacked
• Low maintenance
• Compatibility with the plastics and sealing materials commonly used in mechanical engineering tested and confirmed
• Volume: 25L canister
• Also available as: 60L, 198L barrel

Application

• When preparing the mixture with COOL CONCENTRATE, use only drinking water which does not exceed the following limits:
  • Water hardness max. 20°dH / 35°f/ 350 ppm
  • Chloride max. 100 ppm
  • Sulphate max. 100 ppm
• Prepare a mixture of 11% with COOL CONCENTRATE
• Only use clean containers for preparing the mixture
• Pour the mixture into the prepared cooling system immediately
• If these water values are outside the acceptable limits, the mixture must be prepared with demineralised water or MOTOREX COOL-X ready-mix must be used! Under optimum operating conditions and in compliance with the instructions for use, the COOL CONCENTRATE mixture can remain in use for up to 1 years
• An operating temperature of 20 - 25 °C protects elastomers very effectively in the long term

NOTES: If rotary or swivel tables (i.e. slowly rotating or oscillating components) are cooled from the same coolant tank as the main spindle, we recommend the use of COOL-X AW which provides a higher lubrication capacity or the addition of the lubrication additive Lube 400 to the existing COOL-CONCENTRATE mixture.

Maintenance

• The diluted COOL-CONCENTRATE mixture must be checked periodically according to the specifications of the spindle or machine tool manufacturer
• Before each coolant change, we recommend a system cleaning of the cooling circuit by adding 3 % CS-CLEANER to the coolant to be replaced
• Continue working for 48 hours, then empty and clean the coolant tank and refill with diluted COOL-CONCENTRATE
• Generally observe the maintenance instructions of the spindle manufacturer
