Cabinet Cooler Systems Prevent Heat from Causing Control Panel Problems

No matter the time of year, we routinely help customers solve overheating problems with electrical enclosures.  Sometimes these problems are ongoing and not dependent on the external environment.  Other times, seasonal temperature rises cause enclosure temperatures to creep higher and higher until thermal runaway takes hold and/or components fail.

To prevent an overheating condition, and to keep electronics operational, we help countless customers calculate their heat load and recommend Cabinet Cooler Systems accordingly.

Such was the case for an OEM which contacted me recently with the enclosure below.

Our customer manufactures and installs electrical enclosures for use in industrial environments.  This particular enclosure has been in use for several months, and recently encountered an overheating condition on a hot summer day.  I’ve had the pleasure of working with this particular OEM on multiple occasions, so along with the photos above, they supplied all relevant information from our Cabinet Cooler Sizing Guide, and even the sketch below.

Gathering details like the sketch above allow us to recommend the best possible solution for the problem at hand.  For example, knowing that the cabinet is composed of two sections and completely sealed from each other allowed for installation of (2) separate systems for each side.  This allows for separate temperature controls, tailored to the specific devices inside each side of the cabinet halves.

If you have an application similar to the one above, or need assistance with your application, contact an EXAIR Application Engineer.
