Antifreeze/Coolant Alphacool 18549 1 L Ready to use

Alphacool Eiswasser Crystal Red premixed coolant 1000ml is a ready-to-use antifreeze and coolant formulated for liquid cooling systems in PCs. This 1-litre solution combines corrosion protection, scale prevention and material compatibility while providing a vibrant red colour that helps monitor fluid level and adds visual interest in plexi coolers, tubing and reservoirs. The Crystal series has been laboratory- and field-tested to ensure long life and stable performance.

Advantages

The premixed formula requires no dilution and is safe to use in compatible water-cooling circuits, offering reliable thermal transfer, corrosion inhibition and reduced scaling. Its vivid red dye is designed for visibility in transparent cooling loops and it demonstrates good UV-reactivity when used with suitable UV light sources. The product is non-toxic and intended for long-term system use when installed according to manufacturer guidance.

Suitable for

• Custom PC liquid cooling loops with plexi reservoirs and clear tubing
• Systems requiring premixed coolant for immediate fill

How to use

Use the premixed Alphacool Eiswasser Crystal Red to fill a drained or new water-cooling loop following standard filling and bleeding procedures. Ensure all loop components are compatible with the coolant and that the system is leak-tested before powering the PC. After filling, run the pump with the system powered off as recommended by Alphacool to remove air, then inspect for leaks and verify fluid circulation and temperature stability.

Recommendations

For best results, perform a full system flush with distilled water before introducing the premixed coolant. Avoid mixing with other coolant brands or concentrates to prevent chemical incompatibility. Store the product in a cool, dark place and follow Alphacool’s maintenance intervals for replacing coolant to maintain corrosion protection and appearance.
