The EK-CryoFuel is a new revolutionary coolant for PC liquid cooling systems. EK-CryoFuel is the most chemically stable coolant that provides enthusiasts and gamers with the best possible level of performance and thermal efficiency with emphasis on color stability. EK-CryoFuel coolant is a pure, non-toxic coolant based on the patent pending chemical formula, which prevents the creation of any sediments in the liquid cooling loop. Liquid cooling users can rest assured that the EK-CryoFuel coolant, with its very low viscosity, will not clog or damage their water blocks and other parts of the loop when used with EK-DuraClear or EK-ZMT tubing. The 100mL concentrate is to be mixed with distilled water in ratio 1:9 to form 1L of ready-to-use coolant. Does not contain ethylene glycol or a bittering agent. EK-Cryofuel Loop Superflush is a solution made to flush out manufacturing residues, impurities, and leftover chemicals. It can be used either as a stand-alone solution or after the EK-CryoFuel Loop Cleaner. Stand-alone - prepares a new, unused loop for a new coolant and extends its life, improves stability, and reduces soft tube yellowing. The Superflush concentrate is to be mixed with approximately 2750ml of distilled water (1:11 ratio). This solution does not act as a corrosive inhibitor or biocide for coolants. Compatible with all EK soft and hard tubing. " Includes: 2x 100ml EK-CryoFuel - Clear 1x 250ml EK-Cryofuel Loop Superflush Concentrate Model: TR-701851199157
