As we mentioned before CoolIT presented the prototype of a water cooler system for rack-mount servers. Data centers use powerful air-conditioning systems to cool down the room temperature and thus indirectly control the temperature of the servers. The idea of using water cooling system is to cool down the server temperature to a level that the need or air-conditioning is drastically reduced, making data centers to save on the power bill. CoolIT estimates between 20% to 30% power reductions on data centers if water cooling solution is used.
In Figure 18, you can see the rack prototype closed. The system provides controlling and monitoring through a standard Ethernet port, so you can monitor and control the water-cooling system from anywhere inside your network (the laptop on the prototype is doing this).

With the rack opened (Figure 19) you can see that its door is in fact a huge radiator with two huge fans.

In Figure 21, you can see the rear side of the rack. The hoses and connectors used are industrial grade, used for years on standard hydraulic applications.
