## Summary description

Aqua-Computer Double Protect Ultra is a 1-litre ready-to-use yellow coolant designed for PC and custom liquid cooling loops. It functions as a corrosion inhibitor and biocide to protect metal components and prevent biological growth. Use it to maintain thermal performance, extend component life, and keep radiators, blocks and tubing clean.

## Long description

Aqua-Computer Double Protect Ultra 1L yellow is a ready-to-use coolant formulated for PC and custom liquid cooling loops. It combines corrosion inhibition and biocidal properties in a single, pre-mixed 1-litre solution that helps protect metal components, inhibit microbial growth, and maintain consistent heat transfer across radiators, water blocks and tubing. The transparent yellow fluid is intended for direct use without dilution and is compatible with many common materials used in computer cooling systems when used according to manufacturer guidance.
Advantages
The coolant provides combined corrosion protection and biological control in one product, reducing the need for separate additives. As a ready-to-use formula it eliminates measuring or mixing, simplifying maintenance and refills. Its formulation is designed to help preserve thermal performance by keeping surfaces and coolant pathways free from corrosion deposits and biological fouling. Using a pre-mixed solution also reduces the risk of incorrect concentrations and helps maintain system stability over time.
Suitable for
Desktop PC custom liquid cooling loops with water blocks, radiators and pumps
Systems containing copper, brass, nickel-plated components and common plastics used in cooling assemblies
Maintenance and periodic coolant replacement to control corrosion and biological growth
When it may not be suitable
The product is a ready-to-use coolant formulated for computer liquid cooling systems; it may not be suitable for industrial heat-transfer applications or closed-loop HVAC systems that require different chemical specifications. It is important to verify material compatibility with uncommon alloys or sensitive plastics before use. Do not mix this coolant with other additives unless compatibility is confirmed, as mixing different chemistries can reduce protection or cause precipitation.
Key specifications
Volume: 1 litre ready-to-use coolant
Color: yellow
Main functions: corrosion inhibition and biocide for biological control
Intended use: PC and custom liquid cooling loops for thermal management
Formulation: pre-mixed, no dilution required
How to use
Drain the existing coolant from the loop according to your system’s maintenance procedure, flush the loop if necessary to remove deposits or residue, and refill with the 1-litre ready-to-use coolant. Ensure the loop is free of air pockets by properly bleeding the system and run the pump at low speed initially to check for leaks. After filling, monitor coolant level, temperatures and signs of compatibility issues during the first hours of operation. Follow any additional instructions provided by the system or component manufacturers.
What to consider before purchase
Check material compatibility with your loop components (metals, seals and plastics)
Confirm that a 1-litre volume is sufficient for your loop capacity or whether multiple bottles are required
Avoid mixing with other coolant additives unless compatibility is explicitly confirmed
Usage recommendations
For reliable protection, replace coolant periodically and inspect radiators, blocks and tubing for deposits or growth. When refilling, use the ready-to-use solution as supplied and follow standard leak-testing and bleeding procedures to ensure stable operation.
