## Summary description

Alphacool 18653 is a blue coolant designed for computer cooling systems. It has a capacity of 1 liter and weighs 1.1 kg. This coolant is essential for maintaining optimal temperatures in your system, ensuring efficient performance and longevity of components.

## Long description

Alphacool 18653 Blue 1L (1.1 kg) is a ready-to-use blue coolant formulated for custom PC water cooling loops. The fluid is supplied in a 1‑liter bottle and combines visual color effects with protection and lubrication properties designed for circulating cooling systems. It is intended for use in visible components such as Plexi reservoirs, transparent tubing and distribution blocks where a coloured coolant enhances the system's appearance while providing corrosion and contamination protection.
Advantages
The coolant contains additives that inhibit corrosion, reduce scaling and limit particulate contamination, while lowering surface tension to promote faster bubble dissolution in the loop. Pump lubrication properties help reduce wear on moving parts and can extend pump service life. The formulation avoids aggressive or hazardous ingredients and is designed to be ecologically safe for disposal when handled correctly.
Suitable for
 Custom PC water cooling loops with visible reservoirs and tubing
 Systems using metals and plastics commonly found in cooling loops (see specifications)
 Showcase builds and modded PCs where visual effect is desired
Key specifications
 Color: Blue
 Form: Ready-mix, ready to use from the bottle
 Volume: 1 litre
 Mass: 1.1 kg (bottle full)
 Properties: Corrosion inhibition, anti-scaling additives, reduced surface tension, pump lubrication
 Compatibility: Suitable for common cooling loop materials such as copper, brass, nickel, chrome plated surfaces, aluminium, POM, PPS-GF40, PETG, acrylic, PVC and EPDM/PP
How to use
Use the coolant directly from the bottle; no dilution is required. Fill the drained and clean cooling loop according to the manufacturer’s instructions for your cooling components, ensuring all fittings and seals are correctly installed. After filling, run the pump and bleed the loop to remove trapped air and bubbles, and check for leaks before normal operation. Follow recommended maintenance intervals and inspect the loop regularly for sediment or dye buildup.
Usage recommendations
Avoid mixing this coolant with other biocides, anti-corrosion fluids or distilled water, as mixing or dilution will alter the balanced properties of the product. Due to the dyes, clean the loop more frequently to prevent clogging or reduced cooling performance. The coloured formulation is especially suitable for display and show systems; for continuous heavy-duty or long-term performance-critical workstations consider maintenance frequency when choosing a coloured coolant.
