For those of us in the Northern Hemisphere it can be easy to be overrun by static elimination problems during these winter months. But, colder outside temperatures don’t always mean cooler temperatures for the electronics used in production processes.
I received an email from one of our distributors this week describing two applications with failing electronics (shown above and below). The root cause of failure for both applications was excessive heat inside the enclosures which house electronic devices, even though the ambient air temperatures weren’t abnormally high. So, we used the Cabinet Cooler Sizing Guide to determine the heat load of each application and make recommendations for proper Cabinet Cooler model numbers.
What we found was that the heat load in both cases was rather low, but in each case it was enough to cause the electronics to overheat. When the temperature of the electronic devices exceeds their specified temperature range, they cease to operate, causing downtime of every device tied to the processes they control. By installing a Cabinet Cooler onto each enclosure, the overheating problem will be quickly and easily solved. And, because of the relatively low heat load in this application, a small NEMA 12 type Cabinet Cooler was the perfect solution.
If you have an overheating electrical enclosure, whether during the Winter, Spring, Summer, or Fall, contact an EXAIR Application Engineer. We’ll be happy to help.
