Kühlmittel Alphacool 18671 modrá 5L

Alphacool ES Liquid GL50 (Coolant Alphacool 18671 Blue 5L) is an industrial-grade blue coolant formulated for high-performance computer cooling systems, servers, and workstations. It is suitable for temperatures from -40°C to 90°C and provides reliable thermal conductivity while minimizing maintenance by protecting systems against deposits and corrosion.

Advantages

ES Liquid GL50 flows easily through rubber and plastic components without causing damage, contains no nitrates, phosphates, or amines, and resists foam formation even under high stress. Its formulation provides stable thermal performance across a wide temperature range and helps maintain system cleanliness and longevity. The product is supplied in a 5 L container and is compatible with typical PC and industrial cooling loop materials when used alone.

Suitable for

• Computer liquid-cooling loops (PC cooling systems)
• Server cooling systems
• Workstation cooling setups
• Industrial closed-loop liquid cooling applications within the specified temperature range

How to use

Drain and flush the existing loop according to your system manufacturer's instructions before filling. Do not mix ES Liquid GL50 with other coolants or additives. Fill the loop with ES Liquid GL50, purge air from the system until circulation is stable, then top up to the required level. Check for leaks and allow the system to run briefly to ensure proper flow and temperature stability.

Recommendations

Use ES Liquid GL50 only in single-product fills—mixing with other liquids voids warranty and can alter protective properties. Follow regular inspection and maintenance schedules for fittings, hoses, and radiators to ensure long-term performance.
