Water at this temperature can be produced by the external dry cooler with ambient temperatures of up to 7°C. The same data center operating at a part load of 60% also only requires 60% cooling capacity. Designed for 100% front service access, STULZ Compact Chilled Water (CWE) Systems can be tucked into a corner, placed side-by-side, or between cabinetry. Compact-CWE units are especially adaptable to raised floors and are available in a down-flow air pattern configuration.
