Low noise 3U Heat Extraction Units are designed to be fitted into the front or back of a 19-inch rack to suck hot air out of an enclosure. As hot air rises, the best results will be achieved by mounting them at the top of the cabinet.
A DC-DC link socket is provided, so two or more units can be linked together; a higher power PSU must be used.
Each extractor can also be controlled by a CRC-TEMP thermal sensor.
