Martin In-Row Chilled Water Heat Exchange Cooling (HXU)

Martin In-Row Chilled Water Heat Exchange Cooling (HXU):

In-Row Chilled Water Heat Exchange Cooling is the latest addition to the Martin Enclosures In-Row Solution product offering. As with the PDE, the HXU is enclosed in the same extruded style frame design as the Server Enclosures, and the height and depth are always the same. The width is 12" (half a tile width). Chilled water is delivered to each HXU where the heated air from the rear (hot aisle) is drawn thru the coil and exhausted into the front (cold aisle) of the server racks. The heated water is then returned to the remotely located chiller, removing the heat entirely from the room. Complete monitoring and control are provided both locally using a color touchscreen display, and remotely via Ethernet.
