Liquid to Liquid CDU Test Methodology and Performance Rating, Revision 1.0
Store CDU capacity in the catalogue using this rating basis (kW at 5 C ATD, 1.5 LPM/kW, head and FWS impedance) so units from different vendors can be compared, and derate when the design ATD or flow differs.
- In-row CDU rating: as in-rack, but TCS head at least 40 psi at X x 1.5 LPM.
