The RAIAQUA-T1 from Raijintek is a premixed and ready-to-use coolant that combines the high heat capacity of water with the corrosion, cavitation and frost protection properties of propylene glycol. This results in a very high cooling performance of the water cooling and also a long service life of the same, without the system losing performance due to corrosion, algae formation or other influences.In addition to the excellent performance of the cooling liquid, it also contributes to the appearance of the water cooling - the scope of delivery also includes three 10 ml bottles with coloring additives, which can be used either individually or mixed. This means that strong primary colors, but also many different mixed colors, are possible. Raijintek recommends replacing the coolant every two years so that the corrosion protection is optimally preserved and the cooling performance does not deteriorate.
