## Summary description

Aqua-Computer Double Protect Ultra is a 1 L coolant additive in blue color designed for use in PC liquid cooling and closed-loop cooling systems. It functions as a protective and conditioning agent to maintain coolant quality and system reliability. Supplied in a 1 L bottle, it is suitable for refilling and routine maintenance of water-based cooling loops.

## Long description

Aqua-Computer Double Protect Ultra is a ready-to-use, 1 L coolant additive formulated for PC liquid cooling and closed-loop cooling systems. The blue, water-based solution is engineered to maintain coolant quality, inhibit corrosion, and reduce bubble formation in multi-material loops that commonly include copper and aluminum. Produced in Germany from high-purity components and optimized for low electrical conductivity, this coolant additive supports reliable heat transfer and long-term system stability when used for refilling and routine maintenance of water cooling circuits.
Advantages
Double Protect Ultra combines corrosion inhibitors and conditioners tailored for PC water cooling, minimizing galvanic and other corrosive effects across mixed-metal systems. The formulation reduces electrical conductivity to lower the risk of electrochemical damage and contains surface-active components that reduce bubble formation and improve thermal contact between fluid and water block surfaces. The product is clear, virtually odorless, and supplied ready to use in a 1 L bottle for convenient maintenance and top-ups.
Suitable for
Custom PC water cooling loops containing copper, aluminum and common cooling materials
Closed-loop and refillable liquid cooling systems in desktop computers
Routine coolant replacement and system maintenance
Systems where low electrical conductivity and reduced bubble formation are required
Key specifications
Form: ready-to-use, water-based solution
Volume: 1 liter
Color: blue (appearance in bottle may be darker than in tubing)
Electrical conductivity: minimized for reduced electrochemical risk
Compatibility: formulated for mixed-metal PC water cooling loops (e.g., copper and aluminum)
Odor: virtually odorless
How to use
Use Double Protect Ultra as supplied without dilution. Drain the existing coolant from the loop according to the cooling system manufacturer’s instructions, flush the loop if necessary with distilled water, then refill with the product until the loop is properly filled and free of air pockets. Operate the pump and cycle the system to remove trapped air, topping up as needed. Follow safety precautions for handling liquids and avoid contact with powered components while filling.
Usage recommendations
Replace or refresh the coolant at least annually or according to system conditions. Note that color intensity appears stronger in the bottle than in tubing; compare product images to set correct expectations. Store the bottle capped in a cool, dry place and use within the manufacturer’s recommended period after opening.
