## Summary description

Aqua-Computer Double Protect Ultra is a 1 L green coolant concentrate for liquid cooling systems in PCs and related equipment. The product is formulated to protect against corrosion and biological growth, maintain heat transfer performance, and extend component life. Supplied as a concentrate for mixing with distilled water, it is suitable for custom loops and radiator-based cooling setups.

## Long description

Aqua-Computer Double Protect Ultra 1 L (green) is a coolant concentrate designed for use in custom liquid cooling loops and radiator-based PC cooling systems. Supplied as a concentrate, it is intended to be mixed with distilled water to form a stable coolant that protects metal components from corrosion while inhibiting biological growth. The formulation preserves heat transfer efficiency and helps maintain long-term performance of pumps, radiators and water blocks when used according to manufacturer dilution instructions.
Advantages
This coolant concentrate provides multi-metal corrosion protection suitable for mixed-material loops, includes additives to reduce formation of algae and bacterial growth, and is formulated to maintain thermal conductivity when diluted correctly. As a concentrate, it allows precise mixing ratios to meet system requirements and reduces the risk of contamination compared with pre-mixed liquids. The green tint aids visual inspection of coolant flow and system leaks without affecting coolant performance when diluted to recommended levels.
Suitable for
 Custom PC liquid cooling loops with radiators, pumps and water blocks
 Mixed-metal cooling systems combining copper, brass, nickel-plated and aluminium components
 Maintenance or refill of existing closed-loop water cooling systems after proper flushing
Key specifications
 Form: concentrated liquid to be diluted with distilled water
 Volume: 1 litre container of concentrate
 Colour: green (tint for visual inspection)
 Function: corrosion inhibition and biological growth prevention
 Compatibility: designed for PC liquid cooling systems and radiator-based setups
How to use
Before adding the coolant concentrate, flush the cooling loop thoroughly with distilled water or an appropriate cleaner to remove residues from previous fluids. Mix the concentrate with distilled water according to the manufacturer's recommended dilution ratio to achieve the intended protection and flow characteristics. Fill the loop slowly, bleed trapped air from radiators and blocks, and operate the pump at low speed initially to check for leaks. After filling, run the system and recheck fluid level and tightness of fittings, topping up with the same diluted mixture if necessary.
Usage recommendations
Use only distilled or demineralised water for dilution, avoid mixing with other brands or unknown additives, and perform regular inspections for sediment, colour change or microbial growth. Replace or refresh the coolant according to system maintenance intervals and the manufacturer's guidance to ensure continued corrosion protection and heat transfer performance.
