Coolant liquid ek water blocks EK-CryoFuel Premix Space Black 1000 ml

EK-CryoFuel Premix Space Black 1000 ml is a factory-mixed coolant liquid designed for closed-loop PC liquid cooling systems. Supplied ready-to-use, the formulation delivers stable thermal transfer, protection against corrosion and scale, and long-term optical clarity suitable for transparent and dark-loop builds. The 1000 ml volume covers system fills, refills, and routine top-ups for most consumer desktop water-cooling configurations and is compatible with standard waterblocks, radiators and pumps used in PC cooling circuits.

Advantages

The premixed coolant eliminates the need for additional dilution or additive handling, providing consistent performance out of the bottle. The Space Black tint offers a neutral, low-transparency appearance that reduces visibility of tubing contents while maintaining flow characteristics. The formula includes corrosion inhibitors and biocides to prevent metal degradation and biological growth, supporting long-term system stability and reducing maintenance frequency.

Suitable for

• Desktop PC closed-loop custom water cooling systems
• System fills, refills and reservoir top-ups
• Radiators, waterblocks and pump-filled loops
• Builds where a dark or low-visibility coolant appearance is preferred

Key specifications

• Volume: 1000 ml ready-to-use liquid
• Compatibility: formulated for closed-loop PC liquid cooling components
• Color: Space Black tint for reduced transparency
• Protection: corrosion inhibitors and anti-bacterial/anti-fungal additives
• Optical property: long-term clarity resistance to rapid clouding

How to use

Use the premixed coolant directly from the bottle; no dilution required. Before filling, flush the loop with distilled water or a compatible cleaner to remove residues and ensure the system is drained. Slowly fill the reservoir while the pump circulates to expel air pockets and monitor for leaks. After initial fill, run the loop and top up as necessary until air is fully purged and flow is stable. Follow component manufacturers’ guidance for pump priming and maximum fill levels.

Recommendations

Store the coolant in a cool, dark place away from direct sunlight and extreme temperatures. For best results, pair the coolant with compatible non-reactive tubing and metals; avoid mixing with other coolant brands or unknown additives to prevent precipitation or color shifts. Inspect the loop periodically and replace the coolant according to system usage and visual clarity, typically every 6–12 months for routine maintenance unless manufacturer guidance specifies otherwise.
