EK Water Blocks EK-CryoFuel Premix hűtőfolyadék – Tengerészkék, 1000 ml

The EK-CryoFuel coolant by EK Water Blocks is a chemically stable, transparent blue liquid formulated for PC liquid cooling systems. It is a non-toxic coolant with low viscosity designed to remain color-stable, prevent sediment formation and maintain thermal performance in custom loops. EK-CryoFuel includes corrosion, scale and biological inhibitors and has been tested to meet corrosion standards for copper, brass, aluminum and stainless steel (BS5117 / ASTM D1384). The product is biodegradable (90% within 10 days), has a two-year shelf life from bottling and is compatible with EK-DuraClear and EK-ZMT tubing.

Advantages

EK-CryoFuel provides long-term chemical stability and low viscosity to reduce the risk of clogging in water blocks and other loop components. Its formula contains synergistic corrosion inhibitors and anti-scale and biological agents to prevent fouling and protect metals commonly used in PC cooling loops. The coolant is biodegradable and non-toxic, and its color-stable transparent blue appearance improves loop visibility while preserving thermal efficiency.

Suitable for

• Custom PC liquid cooling loops using copper, brass, aluminum or stainless steel components
• Systems with EK-DuraClear or EK-ZMT tubing
• Enthusiast and gaming builds requiring visible, color-stable coolant

Key specifications

• Type: EK-CryoFuel premixed coolant (transparent blue)
• Compatibility: EK-DuraClear and EK-ZMT tubing; metals: copper, brass, aluminum, stainless steel
• Corrosion testing: BS5117 / ASTM D1384 compliant for listed metals
• Biodegradability: 90% within 10 days
• Shelf life: 2 years from date of bottling
• Viscosity: low (designed to minimize clogging)

How to use

Flush and clean the cooling loop thoroughly before filling to remove any residues from previous fluids. Fill the loop slowly using appropriate filling equipment; EK recommends the dedicated filling bottle to simplify the process. Run the pump with drain ports closed and monitor for leaks, then cycle the system to purge air until the loop is fully filled and stable. Follow normal maintenance intervals and inspect the loop periodically for any signs of contamination or component wear.

Recommendations

Use EK-CryoFuel as supplied (do not dilute) and avoid mixing with unknown additives or other coolants. For optimal performance and longevity, use tubing and components compatible with EK-CryoFuel (for example EK-DuraClear or EK-ZMT) and follow manufacturer cleaning and filling instructions. Store the product sealed in a cool, dry place and use within the two-year shelf life.
