Coolant Liquid Aqua-Computer DP Ultra 5l — Orange, 5 L coolant capacity

The Aqua-Computer DP Ultra 5l — Orange is a ready-to-use coolant for PC water-cooling loops supplied in a 5 L container. Manufactured in Germany from high-purity components, the fluid is formulated for mixed-material systems that commonly include copper and aluminum. The orange color identifies this variant while the liquid itself remains clear and virtually odor-free in operation. The formula reduces electrical conductivity, offers corrosion protection, and improves heat transfer and bubble reduction within the loop.

Advantages

DP Ultra is produced from highly pure raw materials and optimized for the demands of custom desktop liquid cooling. The reduced electrical conductivity lowers the risk of galvanic effects in systems with different metals. Active ingredients are selected to minimize microbubbles and to enhance thermal contact between coolant and cooled surfaces. The coolant is directly applicable without dilution and is formulated to provide long-term corrosion protection and stable thermal performance.

Suitable for

• Custom PC water-cooling loops using mixed metals such as copper and aluminum
• Radiator, water block and pump filling during new builds
• Maintenance refills and seasonal coolant replacement
• Systems where low electrical conductivity and reduced bubble formation are required

When it may not be suitable

This coolant is intended for closed-loop PC water-cooling systems and may not be suitable for open or industrial cooling applications with unusual chemicals or extreme temperatures outside standard desktop operating ranges. If a system contains unusual or incompatible materials not common to PC watercooling, compatibility should be checked before use.

Key specifications

• Volume: 5 litres
• Color: orange (appearance in the loop is clear/transparent)
• Base: water-based solution
• Conductivity: minimized for reduced electrical conductivity
• Corrosion protection: formulated for mixed-metal systems (e.g., copper and aluminum)
• Odor: virtually odor-free in operation

How to use

Use DP Ultra directly from the container; no dilution is required. Fill the loop according to the system manufacturer’s instructions, run the pump to purge air and check for leaks. Allow the system to circulate to remove remaining bubbles, and top up as needed. It is recommended to replace the coolant approximately once per year or according to the maintenance schedule appropriate for your system and operating conditions.

What to consider before purchase

• Ensure materials in your loop are compatible with standard PC watercooling fluids (copper, aluminum, nickel-plated components)
• Plan for an annual coolant exchange as part of maintenance
• Confirm 5 L volume is appropriate for filling and future top-ups for your system
• Colored appearance in the container may differ from the appearance inside a filled loop

Usage recommendations

For best results, flush the loop when changing coolant types, run the system to purge trapped air after filling, and store unopened containers in a cool, dry place. Compare the product images for color differences between the canister and a filled loop.
