DP Ultra is produced from high-quality absolutely pure components in Germany. It has been specifically designed for the requirements of PC watercooling systems which use often mixed materials like copper and aluminum. The electric conductivity has been reduced to an minimum. The active ingredients also reduce the appearance of bubbles in the cooling fluid and optimizes the heat transfer between the surfaces and the fluid making it ideal for use in watercooling systems. 
DP Ultra is a clear and virtually odor free water based solution.

DP Ultra is directly applicable. We recommend an annual exchange of the coolant.
DP Ultra is the result of extensive tests and contains specially selected ingredients to give you an optimum protection against corrosion and ensure an optimum cooling performance.

Advice: Please note that the colored Double Protect Ultra fluids appear different inside the canister compared to the real usage in a loop. Compare the second picture to see the difference.
