The uprights should be designed to provide a cooling air pathway
of at least 140cm2 area. Hitco Carbon/Carbon requires good face
cooling. It is worth monitoring airflow / temperature on both
inside and outside disc faces during testing.
It may be found that a larger face-cooling gap is required for the inside face to equalize the face temperatures. This is due to the tendency of the airflow to bypass this outlet when exiting the upright and flowing mainly up the outside face. The resultant temperature differential can lead to uneven wear, especially if temperature / wear is high.
