EK-CryoFuel Solid non-transparent coolants are all based on a new patent-pending formula with vivid, long-lasting color stability. The coolant contains everything a high-end liquid cooling system requires for efficient thermal performance and providing the necessary protection for your water blocks. It carries the essential synergistic corrosion inhibitors - thus promoting long and safe operational life for your liquid cooling products and high thermal efficiency. With countless hours of in-house and third-party real-life scenario testing, EK-CryoFuel Solid is the most chemically stable coolant that provides enthusiasts with the best possible level of performance and thermal efficiency with emphasis on color stability. The key feature of the new coolant formula is that it is not sedimenting after long hours of inactivity of the cooling loop. Designed specifically for computer liquid cooling systems, the EK-CryoFuel offers a 2-year shelf life from date of bottling. This 250mL concentrate is to be mixed in 750mL distilled water to form 1L of ready-to-use coolant.
