XSPC coolant concentrate 150 ml – yellow UV-reactive liquid for PC water cooling systems

XSPC coolant concentrate 150 ml is a yellow UV-reactive liquid formulated for custom PC water cooling systems. Supplied as a concentrated solution, the product is intended to be mixed with distilled water to produce a fluorescent coolant that enhances visibility in illuminated loops while delivering corrosion inhibition for metallic and non-metallic components. The compact 150 ml bottle is suitable for preparing small volumes for initial fill, top-ups, and maintenance tasks in closed-loop liquid cooling setups.

Advantages

The concentrate provides bright yellow UV fluorescence when exposed to UV or RGB lighting, improving visual monitoring of flow and leak detection. Its formulation targets corrosion protection for common loop materials, helping to extend the life of radiators, water blocks and fittings. Concentrated packaging reduces shipping weight and storage space compared with ready-to-use liquids and allows users to control final coolant strength by adjusting mixing ratios with distilled water.

Suitable for

• Preparation of fluorescent yellow coolant for custom PC water cooling loops
• Small top-ups and maintenance of closed-loop systems
• Mixing with distilled water to achieve desired concentrate ratio for RGB/UV lighting effects

Key specifications

• Volume: 150 ml concentrate intended for dilution
• Colour: yellow, UV-reactive for fluorescence under UV/RGB lighting
• Application: designed for use in closed-loop PC water cooling systems
• Compatibility: suitable for common loop materials including copper, brass, aluminium, plastics and rubber when mixed as directed

How to use

Determine the required final volume of coolant for your loop and calculate the appropriate amount of concentrate to mix with distilled water according to manufacturer guidance. Add the measured concentrate to a clean container, then pour in distilled water and mix thoroughly until homogeneous. Fill the cooling loop following the system manufacturer’s recommended filling and bleeding procedure, operate the pump to circulate the mixture and inspect for leaks. After initial circulation, drain and refill if manufacturer instructions advise flushing before the first use.

Usage recommendations

Always dilute the concentrate with distilled water; do not use tap water. Use gloves and avoid contact with skin and eyes. Store the bottle upright in a cool, dark place away from direct sunlight and sources of heat. Perform routine visual inspections of the loop and replace coolant at intervals recommended by the cooling system or component manufacturers.
