Temperature, moisture and contaminants
Home and office electronics operate in climate-controlled rooms, but industrial devices are often subject to temperature extremes. Many industrial devices are installed outdoors in unventilated sealed enclosures, which freeze in winter and heat to extremely high temperatures in summer. Industrial devices and their power supplies are expected to perform over a wide temperature range. Typically they are rated so you can select one appropriate to your environment. Temperature tolerances from -25 to +60° C are common and you can even find devices rated for extremes to -40 to +75° C. Because industrial components are sealed against contaminants and also because they are often installed inside enclosures, they rely on air convection rather than fans for cooling.
