What it is for
Alphacool offers the GL50 as an industrial coolant for powerful cooling. Thanks to its composition it protects against deposits, flows easily through all types of rubber and plastic parts and requires little maintenance. Servers and workstations in particular benefit from these properties, Alphacool says.
Top Performance
Alphacool states that the thermal conductivity is reliable and at the highest level even at extreme temperatures. Foam formation is also not a problem: the heavy-duty coolant effectively prevents this. Despite the blue color, there are no deposits. According to Alphacool the coolant protects the system sustainably and thus ensures low maintenance and a long service life.
Protection
The specially formulated liquid provides reliable protection for the metals and alloys used in water cooling systems, and Alphacool says it effectively prevents high-temperature corrosion on aluminum surfaces. Avoid a mix of pure copper and aluminum in the same cooling loop all the same. Plastic and rubber components, such as tubes, do not react with the liquid. As a silicate liquid it is free of nitrates, phosphates and amines, so it can be used neutrally in any system.
