Refrigerante EK Water Blocks 0,25 L

EK-CryoFuel Loop Cleaner + Superflush is a two-part concentrated kit for cleaning and flushing custom PC water-cooling loops. The kit includes EK-CryoFuel Loop Cleaner, a liquid cleaning concentrate for removing manufacturing residues, old coolant stains and impurities, and EK-CryoFuel Loop Superflush, a flushing concentrate designed to pick up and rinse any remnant chemicals after cleaning. Both concentrates must be diluted with distilled water before use and are compatible with all EK soft and hard tubing.

Advantages

The combined system provides a structured two-step procedure: first, the Loop Cleaner breaks down and dissolves deposits and contaminants; second, the Superflush removes cleaner residues and remaining impurities to leave the loop ready for new coolant. Concentrated formulas allow mixing to the required volumes for full-system circulation. The products are formulated for use in custom PC liquid cooling loops and radiators and help prepare or restore loop cleanliness without introducing additional corrosion inhibitors or biocides.

Suitable for

• Cleaning used custom PC water-cooling loops before refilling
• Preparing a new, unused loop prior to first fill
• Flushing radiators and blocks to remove manufacturing residues
• System maintenance and troubleshooting to eliminate old coolant stains

Key specifications

• Contents: EK-CryoFuel Loop Cleaner (250 ml concentrate) and EK-CryoFuel Loop Superflush (concentrate)
• Loop Cleaner dilution ratio: 1:5 (250 ml concentrate + 1250 ml distilled water)
• Loop Cleaner circulation time: 2–24 hours
• Superflush dilution ratio: ~1:11 (mix concentrate with approximately 2750 ml distilled water)
• Compatibility: all EK soft and hard tubing
• Note: neither solution functions as a long-term corrosion inhibitor or biocide

How to use

Mix the Loop Cleaner concentrate with distilled water at a 1:5 ratio (250 ml concentrate + 1250 ml distilled water). Pour the prepared solution into the emptied cooling loop and run the pump to circulate the fluid for 2 to 24 hours, then drain. Next, mix the Superflush concentrate according to the recommended dilution (approximately 1:11) and circulate the flushing solution to remove any remaining cleaner residue and contaminants. After flushing, drain the system thoroughly and rinse if needed before filling with your chosen coolant.

Recommendations

Do not leave either solution in the system significantly longer than the specified circulation time. These concentrates are cleaning and flushing agents only; they do not provide long-term corrosion inhibition or biocidal protection. Use distilled water for dilution and follow safe handling and disposal practices for used fluids.
