Rittal's Thermal Management Solutions white paper outlines the impact of increasing temp-eratures on the lifespan of electronics housed in enclosures.
The average lifespan of semiconductors is reduced by roughly 50% every time the operating temperature rises 20°F. / 10°C. over its maximum operating temperature. The failure of a single electronic component may lead to the complete shutdown of an entire production line. Resulting costs add up quickly.
Unfortunately high temperatures in enclosures can be difficult to control because electronic equipment such as transformers, power distribution components, drives, PLCs, and PCs all generate heat.
Air conditioners currently are the only practical stand-alone device in the market that can cool an environment below ambient temperature.
This white paper provides useful tips and techniques on sizing an air conditioning unit for a specific enclosure application, guidance on how to interpret an air conditioner's performance chart, tips on comparing specifications, and insights into the impact of humidity.
Rittal's TopTherm roof-mounted and wall-mounted unit options are described, as are various mounting options and controllers.
A feature/benefit comparison chart makes it easy to evaluate the latest TopTherm units in contrast with earlier Rittal offerings and competitive A/C units.
