CDR High IT power density chilled water CRAC units with underfloor fans

CDRs are the brand new range of chilled-water air conditioners for high density computer rooms. In-depth fluid dynamic analysis has resulted in the meticulous design of every last constructive detail to minimize air pressure drops and, therefore, minimize fan power consumption, the only power input in the unit. The base module allows for wider air through-flow while the “E-Wing” profile separates the airflows coming from each fan. This reduces contact/impact between the two flows and, therefore, any possible fan air pressure drops . Using fans with electronic EC motors allows for precise, efficient air flow adjustment, while the higher power density (dual chilled-water coil) also makes the range suitable for applications which are more critical in terms of the heat loads to be dispersed.

The FCDR range is suitable for systems that make use of Free-Cooling. Ultra-low thermal approaches between chilled water and air increase the scope for using indirect Free-Cooling, with further reductions in system PUE levels and running costs.
