Temperatures are heating up across the US, when this happens it can wreak havoc on the sensitive electronics in your facility. If you’re a follower of the EXAIR Blog, you’ve noticed that we’ve spent a great deal of time recently discussing the Cabinet Coolers. From a description of how they work, specific applications, as well as how to determine what size you’ll need, we’ve covered quite a range of topics. Equally important, though, is the NEMA rating of the Cabinet Cooler. I’d like to take a moment to discuss the different NEMA ratings for the Cabinet Coolers that EXAIR has to offer and where each should fit.
NEMA 12 – The NEMA 12 rating is for enclosures that are indoor and provide a degree of protection to personnel against access to hazardous parts as well as prevent any materials from entering the enclosure such as dust, debris, or moisture from light splashing. This standard duty style of Cabinet Cooler is best served indoors on the shop floor where there aren’t any wash-down areas or excessive moisture.
NEMA 4 – A NEMA 4 rated cabinet cooler is designed for either indoor or outdoor use. It, too, provides protection to personnel against access to hazardous parts and prevents dust, dirt, or debris from entering the cabinet. In addition to providing the same levels of protection as the NEMA 12, the NEMA 4 rating also means that the equipment will be protected from water such as rain, sleet, snow, splashing water, and even hose directed water.
NEMA 4X – The NEMA 4X carries the same levels of protection as the NEMA 4, but also adds an additional level of protection against corrosion. EXAIR’s NEMA 4X Cabinet Coolers are constructed of either 303 or 316 Stainless Steel.
