Standard units operate without regulation, running constantly at full speed, even in reduced temperatures. Rittal’s units feature a sensor which measures the temperature within the enclosure and controls the fan speed as required. The units, which shutdown at below 20°C, are claimed to be up to 30% more efficient than standard AC fan-and-filter units.
