Computer cooling system Alphacool 18548 Transparent 1L liquid coolant

Alphacool Eiswasser Crystal UV is a transparent liquid coolant for custom PC water-cooling loops. Developed by Alphacool, this 1 L coolant combines visual clarity with material compatibility and a long service life; it has been lab-tested and validated by external testers and modders for stable performance in various loop configurations. The UV-reactive formula enhances illumination when used with UV-LEDs or UV cathodes, adding a visible effect in plexi coolers, reservoirs and tubing.

Advantages

The coolant offers clear optics and pronounced UV-reactivity for systems with ultraviolet lighting, while maintaining compatibility with common loop materials and reliable thermal performance. It is supplied in a 1 L bottle suitable for filling or topping up reservoirs and delivers long-term stability under normal operating conditions.

Suitable for

• Custom PC water-cooling loops (radiators, blocks, reservoirs)
• Systems using UV illumination (LEDs or cathodes)
• Modding projects where visible coolant effects are desired

For topping up, add small amounts while the system is running and monitor levels and clarity periodically.

Recommendations

Use only in closed-loop PC water cooling systems; avoid mixing with other coolant brands or additives to prevent compatibility issues. Store the bottle tightly closed in a cool, dark place and follow Alphacool’s guidance for maintenance intervals and material compatibility checks.
