How to check if cooling output inside enclosures is sufficient
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.
