HP Modular Cooling System or MCS is designed for high density server and blade deployments. It recirculates and cools the hot server exhaust air through heat exchangers residing in the MCS unit. The air is then expelled in front of the enclosed rack at a much lower temperature providing sufficient cool air for a load of 35kW of servers or blades.

The MCS unit contains three fans and three heat exchangers deployed along the full height of the rack to ensure that all the equipment installed receives sufficient cooled air. All fans and heat exchangers are swappable while the unit is online, providing great servicing flexibility. Redundant power is ensured through a failover power switch that can be connected to two power sources. The environmental monitor controls the air temperature to the servers and adjusts automatically to meet the pre-established air temperature goal.
