Cooling performance is rated at 43 ˚F EWT. MCS with Expansion Rack capacity/airflow is pooled and does

not have to be evenly split between racks. For example, the HP Modular Cooling System 200/100 with 3

fans, provides at total of 2,800 CFM. One rack can use 2,000 CFM and the other can use 800 CFM.

A minimum heat load is necessary for operating the MCS-200/100 properly. This minimum depends on the

water supply temperature as shown in the following table.
