WOPR-ER 0015÷0030

HIGH PERFORMING CHILLED WATER IN RACK ENCLOSURE + REDUNDANCY CONDITIONING UNITS

It is also possible to achieve a fully redundant system WOPR-ER by coupling the rack with two chilled water cooling modules. These systems are flexible, easy to be implemented and they are the perfect solution for different applications such as micro data centers, high density servers, EDGE computing, IOT applications, 5G devices. The two modules can operate in a Master/Slave configuration with one unit working and one unit in stand-by with rotation of the stand-by unit on time basis.
These units are equipped with EC Inverter Plug-Fans with backward curved blades and a cooling coil optimised to operate with high inlet water temperature and a large ∆T. Variations in heat load are controlled by the simultaneous action of a 2-way or 3-way modulation valve and automatic fan speed control by means of microprocessor-controlled control logic and an advanced user interface.
