MOTOREX COOL-PROTECT CONCENTRATE Spindle Coolant 20L

MOTOREX COOL-PROTECT CONCENTRATE is a water-miscible coolant concentrate for closed-loop motor spindle cooling systems and other temperature-sensitive applications. Its balanced additive technology helps protect the metals, plastics and sealing materials used in the cooling circuit against corrosion, cavitation damage and deposit formation.

• Pack size: 20 L canister
• Also available in: 5 L canister, 200 L drum
• Note: Mix with clean drinking water before use.
• Recommended standard mixture: 25 % concentrate
• In-use concentration: 25–30 %

Applications

• Closed-loop motor spindle cooling systems in machine tools
• Cooling circuits for tool and motor spindles
• Other temperature-sensitive applications with closed cooling circuits

Features

• Helps prevent electrochemical corrosion
• Protects aluminium, ferrous and non-ferrous metals
• Helps protect plastics and sealing materials in the closed cooling circuit
• Protection against cavitation damage and deposit formation
• Stable thermal conductivity for efficient heat dissipation
• Helps maintain a constant spindle temperature
• Low-maintenance and designed for long-term use
• When correctly mixed and used under optimal conditions, the coolant can remain in the system for up to 2 years

Mixing & Operation

• Mixing: Mix the concentrate with clean drinking water in a clean mixing container.
• Standard mixture: Prepare a mixture containing 25 % COOL-PROTECT CONCENTRATE when changing the coolant.
• Water quality: water hardness max. 20 °dH, chlorides max. 100 ppm, sulphates max. 100 ppm.
• Concentration check: use a refractometer – reading × factor = effective concentration.
• Routine checks: check pH and concentration monthly.
• Topping up: compensate evaporation losses with mixed coolant or ready-mixed coolant. If the concentration reaches the upper limit, adjust it back to the reference value with clean drinking water.

Technical Data

Commissioning & Maintenance

• Initial commissioning: fill the circuit with drinking water, circulate for at least 10 minutes and then drain completely.
• Routine checks: check pH and concentration monthly; observe the refractometer factor.
• Topping up: compensate evaporation losses with mixed coolant or ready-mixed coolant.
• Concentration adjustment: if frequent topping up increases the concentration to the upper limit, adjust it back to the reference value with clean drinking water.
• Coolant change: prepare a mixture containing 25 % COOL-PROTECT CONCENTRATE in a clean container and immediately fill the prepared cooling system.
