Coolant EK Water Blocks

EK-CryoFuel coolant by EK Water Blocks (EAN 3831109813263) is a high-performance liquid coolant for PC liquid cooling systems. It is a chemically stable, non-toxic formula offered in a transparent red color that emphasises color stability while providing low viscosity for reliable flow through water blocks, tubing and other loop components. The formula includes corrosion, scale and biological inhibitors and has been tested to meet corrosion standards for copper, brass, aluminum and stainless steel. EK-CryoFuel is biodegradable and has a two-year shelf life from bottling.

Advantages

EK-CryoFuel delivers low viscosity for unobstructed flow and is formulated to prevent sediment formation, reducing the risk of clogging and damage in water blocks and fittings when used with compatible tubing such as EK-DuraClear or EK-ZMT. The coolant contains synergistic corrosion inhibitors and scale/biological inhibitors to protect common metals in PC loops and to limit fouling, supporting stable long-term thermal performance. It is non-toxic and biodegradable (90% in 10 days), and the product has a 2-year shelf life from the date of bottling.

Suitable for

• Custom PC liquid cooling loops using water blocks, radiators and reservoirs
• Enthusiast and gaming PCs requiring corrosion protection for copper, brass, aluminium and stainless steel
• Systems using EK-DuraClear or EK-ZMT tubing to ensure compatibility and flow

How to use

Fill the liquid cooling loop according to the system manufacturer’s instructions using the EK-CryoFuel coolant. EK recommends using the dedicated filling bottle to make the filling process easier and more controlled. Ensure the loop is flushed and clean before filling to remove any residues from previous fluids, then circulate the coolant and inspect for leaks. Run the system for a short period while checking flow and temperatures, then top up as needed and close the loop.

Recommendations

Use EK-CryoFuel with compatible tubing such as EK-DuraClear or EK-ZMT and avoid mixing with unknown coolants. Flush the loop thoroughly before switching to EK-CryoFuel and perform periodic inspections to ensure anti-corrosion and anti-fouling performance over time.
