2. Alphacool Ultra Pure Water
Water produced especially for Alphacool directly from a high-quality reverse osmosis system. Purified by 5 special filters (one of which is a special reverse osmosis filter), the water is absolutely free of salts, metals and germs, i.e. all those components that are found in normal tap water. The process eliminates chlorine, odours, heavy metals such as lead, copper, cadmium, mercury, etc. Agricultural chemistry, hormones, antibiotics, pesticides, fungicides, herbicides, drug residues, carcinogenic organic chlorine compounds, radioactive substances, asbestos fibres, tar compounds, nitrites, nitrates, bacteria, viruses, fungal spores, cysts. This means that the water leaves no residue whatsoever during evaporation and no limescale deposits are formed. On the contrary: Due to the low PH value of 6.0 - 7.0, Ultra Pure Water even absorbs deposits (up to a certain amount), so that the cooling system remains permanently clean.
3. Aqua Computer Double Protect Ultra
DP Ultra is the result of extensive testing and contains specially coordinated active ingredients that guarantee optimal protection against corrosion and optimal cooling performance.
The production takes place under high-quality standards and using the highest quality, absolutely pure active ingredients, entirely in Germany.
DP Ultra has been specifically developed for use in PC cooling systems with copper and aluminum components and is only extremely low in electrical conductivity. The active ingredients also reduce bubble formation and optimize heat transfer at surfaces by improving the flow behavior of the coolant, resulting in optimal cooling performance in your system. DP Ultra is a clear and nearly odorless solution.
DP Ultra was developed directly by Aqua Computer in collaboration with Dr. Tobias Voigt. Compared to other available ready-made mixtures, DP Ultra achieves very good cooling performance and improves flow behavior due to its ingredients.
DP Ultra is pre-dosed and ready to use. We recommend an annual coolant replacement.
Note: Please be aware that the colored Double Protect Ultra ready-made mixtures in the canister appear visually different than in the hose. Please refer to the second image, which shows the mixture in the hose.
4. Corsair Hydro X Series XL5
Corsair Hydro X Series XL5 Performance Coolant brings your custom cooling system's color scheme to life and is available in a wide range of vibrant, translucent colors. The pre-mixed and ready-to-use XL5 Performance Coolant contains corrosion and antibacterial inhibitors that keep your custom cooling system clean and cool. It is designed to protect fittings and blocks made of copper, brass, and nickel, while adding vibrant colors and cool temperatures to your custom cooling system.
5. Alphacool Ice water
With the Alphacool Ice Water Crystal, the water cooling pioneer Alphacool fulfils the wishes of many modders and enthusiasts: crisply beautiful colours, great effects in Plexi coolers, hoses and expansion tanks as well as longevity and compatibility with the materials used. The Alphacool Ice Water Crystal series has been tested for more than 1.5 years for all possible applications in the Alphacool laboratory as well as by external testers and modders and has been found to be very good and durable. If you want to give your PC an extra portion of luminosity, you can use the Alphacool Crystal UV ice water. The UV reactivity with UV LEDs or cathodes is outstanding. With the Alphacool ice water you give your water cooling an optical highlight with best cooling performance and longevity.

6. Aqua Computer Double Protect Ultra 5l canister
DP Ultra is the result of extensive testing and contains specially coordinated active ingredients that guarantee optimal protection against corrosion and excellent cooling performance. It is produced under high-quality standards and using the highest quality, completely pure active ingredients, entirely in Germany. DP Ultra has been specifically developed for use in PC cooling systems with copper and aluminum components and is only minimally electrically conductive. The active ingredients also reduce bubble formation and optimize heat transfer at surfaces by improving the flow behavior of the coolant, leading to optimal cooling performance in your system. DP Ultra is a clear and nearly odorless solution. DP Ultra was developed directly by Aqua Computer in collaboration with Dr. Tobias Voigt. Compared to other available ready-to-use mixtures, DP Ultra achieves very good cooling performance and improves flow behavior due to its ingredients. DP Ultra is pre-measured and ready to use. We recommend an annual replacement of the coolant.

7. Aquatuning AT-Protect Crystal Blue
Ready-to-use coolant that can be added directly from the bottle into the cooling system without mixing with water. Specifically developed for closed water cooling systems, it provides effective and long-lasting corrosion protection for PC cooling systems that use different materials (e.g., copper, brass, plastics, seals). The included corrosion inhibitors work effectively and preventively, protecting the system over an extended period.
The dosing is very simple, as AT-Protect can be used undiluted to fill a water cooling system. To maintain the exact dosage, AT-Protect must not be diluted further (e.g., with water). AT-Protect is odorless, colorfast, non-flocculating, and glows in its characteristic color when exposed to UV light (LEDs, cathodes).
AT-Protect-UV-green does not contain Glysantin or glycol, and therefore does not reduce the water's heat absorption. This makes it particularly suitable for high-performance PC water cooling systems.
Warnings: Contains ethylene glycol. Keep out of reach of children, rinse immediately with water in case of contact, and seek medical attention.
Note: Since this concentrate contains dyes, it is possible that it may stain clothing or other materials upon contact. We also want to point out that dyes may fade over time, which can lead to a decrease in color intensity.
