DP Ultra is the result of extensive tests and contains specially coordinated active ingredients that guarantee you optimum protection against corrosion and optimum cooling performance. The production takes place under high quality standards and the use of high-quality, absolutely pure active ingredients completely in Germany. DP Ultra was specially developed for use in PC cooling systems with copper and aluminium components and is electrically only extremely low conductive. The active ingredients also reduce the formation of bubbles and optimise heat transfer to surfaces by improving the flow behaviour of the coolant, resulting in optimum cooling performance in your system. DP Ultra is a clear and almost odorless solution. DP Ultra was developed directly by Aqua Computer in collaboration with Dr. Tobias Voigt. DP Ultra achieves very good cooling performance compared to other ready-to-use compounds and improves the flow behaviour due to its ingredients. DP Ultra is ready dosed and directly applicable. We recommend an annual replacement of the coolant. Scope of delivery: Aquacomputer Double Protect Ultra - Red 1000ml (not UV active) Colour hint: Please note that the coloured Double Protect Ultra ready-to-use mixtures in the bottle have a different optical effect than in the tube. Note: Since this concentrate contains dyes, it cannot be ruled out that it may discolour clothing or other materials on contact. We would also like to point out that dyes fade over time and therefore the intensity of the color can decrease.
