Why is Liebert XD called Supplemental High Heat Density Cooling?
The Liebert XD system is doing sensible cooling (the temperature of the cooling fluid supplied to the cooling modules is always above the actual dew point in the room so no condensation can occur on the coils in the modules or on the piping) to match the high heat density load. It supplements the precision cooling equipment which typically still is required for humidity control and air filtration.
