Manufacturing automation systems are delicate and very expensive pieces of kit, which perform vital functions for the businesses they serve.
Unlike speed-controlled cooling devices such as the new Rittal Blue e+ cooling units, conventional enclosure cooling units begin with the two-point regulation of the cooling operation when a temperature inside the enclosure gets above of 35°C and finishes when the shutdown temperature of 30°C is achieved (at a typical hysteresis of 5K). If a cooling device does not reach the shutdown temperature, a conventional cooling unit will therefore continue to operate.
If this happens, it’s a good indication that the cooling unit has an insufficient output and suggests there is likely to be a deficiency in suitable cooling air to the components inside the enclosure.
