Kølemiddel Alphacool 18599 blå 1L

Alphacool ES Liquid GL50 (Coolant Alphacool 18599 Blue 1L) is an industrial-grade blue cooling liquid formulated for high-performance computer and server cooling systems. It is designed for reliable thermal transfer in closed-loop liquid cooling setups and is suitable for use in servers, workstations and custom PC loops where long-term stability and low maintenance are required.

Advantages

ES Liquid GL50 provides stable thermal conductivity across a wide temperature range from -40°C to 90°C and resists foam formation. Its silicate-based composition avoids nitrates, phosphates and amines, which prevents attack on rubber and plastic parts and reduces deposit formation. The fluid is formulated to flow easily through various rubber and plastic components, offering sustained protection and lower maintenance needs for cooling systems.

Suitable for

• Server liquid cooling loops
• Workstation cooling systems
• Custom PC water-cooling loops
• Closed-loop industrial cooling applications within specified temperature range

How to use

Fill the cooling loop or reservoir with the Alphacool ES Liquid GL50 according to the system manufacturer’s instructions. Ensure the system is clean and free of other coolants before filling to avoid mixing. After filling, run the pump and bleed the loop to remove air pockets, then check for leaks and verify flow. Maintain regular visual inspections and top up only with the same product if necessary.

Recommendations

Do not mix ES Liquid GL50 with other coolants. Mixing may void the warranty and negatively affect fluid properties. Use only in compatible closed cooling systems and follow component manufacturers’ guidelines for materials compatibility and maintenance.
