The scope of use

Ambient temperature: -40—85℃

Liquid temperature: -40—85℃

Liquid type: Commercial coolants can be used with water pumps, but mixing different coolants is not allowed. The mixing ratio of water and antifreeze is selected in a range of 50/50 to 40/60.

In order for the cooling system to be completely filled with media, the cooling system must be completely drained to a vacuum.

Installation: Vibration and noise requirements must be taken into account in the definition of the installation location and specific fixing elements/fasteners in the application, and the installation position must avoid water accumulation on the surface/inside the connection system.

Typical applications: Energy storage thermal management system, liquid-cooled charging cabinet, data center system
