Coolant XSPC Pure Coolant 1 L (red UV) for PC liquid cooling systems

XSPC Pure Coolant 1 L (red UV) is a concentrated coolant formulated for custom PC liquid cooling systems. Supplied as a one-litre concentrate, it is designed to mix with distilled water to form a stable, visually distinctive red UV fluid suitable for radiators, water blocks and tubing used in desktop or workstation cooling loops. The formula provides corrosion inhibition and helps maintain thermal performance and component longevity when used in compatible metal and plastic loop components.

Advantages

The coolant offers clear visual identification with a red UV-active tint that enhances loop aesthetics under UV lighting while remaining chemically balanced for long-term use. Its concentrated form reduces shipping volume and allows users to prepare the desired fill ratio with distilled water. The formulation includes corrosion inhibitors and additives to limit scale and deposit formation, supporting steady flow and heat transfer in closed-loop PC cooling systems.

Suitable for

• Filling or refilling custom PC water-cooling loops
• Topping up coolant in desktop or workstation liquid cooling systems
• Changing coolant during maintenance or upgrades of radiators, pumps and blocks
• Systems using copper, brass, aluminium (when compatible), nickel-plated blocks and common plastic tubing

Key specifications

• Volume: 1 litre concentrated coolant
• Color: red UV-active tint for visibility under UV lighting
• Formulation: concentrate to be mixed with distilled water
• Main functions: corrosion inhibition, deposit control and flow stability
• Intended use: closed-loop PC liquid cooling systems (radiators, blocks, tubing, pumps)

How to use

Prepare the coolant by diluting the concentrate with distilled water according to the manufacturer’s recommended ratio. Flush the loop with distilled water or an appropriate cleaner before adding the prepared mixture. Fill the reservoir slowly while running the pump at low speed to remove air bubbles; continue cycling and topping up until no air remains. After filling, check all connections and run the system for a short period while monitoring for leaks and verifying stable flow and temperatures.

Recommendations

Use distilled water only when mixing to avoid mineral deposits. Perform periodic visual inspections and replace or top up coolant as part of regular maintenance; if discoloration, cloudiness or reduced flow appears, drain and flush the loop before refilling. Avoid mixing with incompatible additives or other proprietary coolants unless explicitly stated as compatible by the manufacturer.
