We are cooling 15KW/rack for high performance computing using the Trox 
CO2 system:

Obviously this is a very new technology for the moment but I think our 
experiences have been favourable. I'm not an expert but I think we 
reject heat directly outside (300KW plant) but they also have systems 
designed to exchanged directly into building chilled water.
