Clear coolant looks simple, but the chemistry decides how long a loop stays healthy. The base is deionised water, kept so clean that conductivity reads under 5 µS/cm straight from the bottle. The biocide holds biological growth at zero across the full 24-month shelf life, and the anti-corrosion package protects copper, brass and nickel alike, so one fluid can run through the whole build without concerns.Conductivity is the number that matters in a sealed system. Should the loop leak, pure water shorts whatever it lands on; CryoFuel stays practically non-conductive, so a spill wipes clean instead of taking a board with it. That is also why we bottle it pre-mixed — concentrate demands precision, and one careless litre of tap water can undo the formula. Every batch is sampled before bottling and must pass the same 5 µS/cm ceiling.
