AFC02-AZ(10)

AFC02-AZ(10) is Bitmain's antifreeze coolant for liquid-cooled mining equipment; Bitmain lists it as version V1.0 of the AFC02-AZ, and its support centre publishes the same data as ANTSPACE AZ. It is a glycol solution at 53% by volume with a freezing point of -40 °C, and Bitmain describes it as suitable for all of its hydro-cooling products.

Compatibility

• ANTSPACE hydro-cooling containers
