This bundle includes EK-CryoFuel and the EK-Loop Foldable Filling Bottle. 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. EK-CryoFuel contains synergistic corrosion inhibitors to protect metals commonly found in computer liquid cooling systems. It has been tested in accordance with BS5117 (ASTM D1384) and found to meet corrosion standards for copper, brass, aluminum and stainless steel. Does not contain ethylene glycol or a bittering agent. EK-Loop Foldable Filling Bottle is designed to make your loop filling process much easier. The telescopic tube of the filling bottle can reach even the most remote and crammed fill ports. The narrow tube does not require the user to unscrew the entire reservoir cap to fill the loop with coolant, removing the fill port plug is more than enough. It can also be used to mix your EK-CryoFuel coolant precisely, as the EK-Loop Foldable Filling Bottle has clearly marked coolant volume inside. It contains up to 1000ml (1 liter) with the markers incrementing every 100ml up to that point. For easier visual determination where the coolant level currently is, the milky white bottle has a thin translucent strip that reveals the coolant level at a glance. Foldable nature of this filling bottle also makes it extremely convenient to carry with you wherever you might need it, due to small dimensions it can pack in. This newly designed bottle comes with new EK-Quantum Kits as well as the new EK-Classic D-RGB kits. Model: TR-88032-82243
