Coolant Aqua-Computer Double Protect Ultra 1 L — red

Aqua-Computer Double Protect Ultra 1 L — red is a concentrated coolant for custom PC water cooling loops. Formulated to protect metal and mixed-material circuits, this red coolant concentrate reduces corrosion and inhibits biofouling while maintaining thermal transfer properties. The product is intended for filling, refilling and topping up radiators, water blocks and reservoirs in liquid-cooled computer systems.

Advantages

This coolant provides corrosion protection for commonly used loop materials and includes additives that prevent microbial growth and deposits. As a concentrate, it can be diluted to the recommended ratio to obtain the required red color and performance. The formulation is compatible with typical water-cooling components and supports stable thermal performance over extended service intervals.

Suitable for

• Custom PC water cooling loops with mixed metals and plastics
• Filling or topping up radiators, water blocks and reservoirs
• Maintenance cycles where corrosion and biofouling protection is required

Key specifications

• Volume: 1 L concentrate
• Color: red (concentrate)
• Intended use: coolant concentrate for PC liquid cooling systems
• Protection: corrosion inhibition and biofouling prevention for mixed-material loops
• Compatibility: suitable for common water-cooling metals and plastics when used as directed

How to use

Dilute the concentrate according to the manufacturer’s recommended ratio before use to achieve the specified performance and color. Fill or top up the cooling loop with the prepared solution, ensuring the system is properly bled of air pockets and that all components are compatible with the coolant. After filling, run the pump and inspect the loop for leaks and for stable flow; monitor temperatures to confirm thermal performance.

Usage recommendations

Use distilled or demineralized water for dilution to avoid mineral deposits. Adhere to regular maintenance intervals: inspect the loop periodically, replace coolant according to system needs, and flush the circuit if contamination or discoloration appears. Store the product in a cool, dark place and keep the container tightly closed when not in use.
