Summer has not officially arrived in the Northern Hemisphere, according to the calendar, but temperatures have started to push 90 degrees Fahrenheit here in Cincinnati. As the temperatures increase, your electronics may start to feel the heat. High temperatures can cause circuits breakers to trip, controllers to shutdown, and connectors to be very sensitive. We have seen electronics lose machine control, report bad readings, or if the heat is not managed promptly, damage circuitry. EXAIR Cabinet Coolers Systems are a simple, quickly installed and effective solution to heat related problems. Beside being installed in minutes and shipping from stock, they have additional benefits over fans, air conditioners and heat exchangers.
During the heat of the summer, fans, air conditioners, and heat exchangers may fail when you need them most. For instance, a fan and a heat exchanger work because the temperature differential between the ambient temperature and the inside of a cabinet is large. As the temperature rises, the ambient temperature goes up and a fan or heat exchanger lose their ability to remove heat from the cabinet. In a climate controlled environment this works great, in a hot plant floor without air conditioning, it is a recipe for failure.
So if fans aren’t a good solution you may turn to air conditioners in the summer because they can still produce very cold air at much higher ambient temperatures. You will need hours to install them, cross your fingers that they arrive undamaged, hope the condenser and other moving parts don’t fail and provide a drain for the condensate. If you are in a dusty environment, the filters will clog more often in the summer and require more maintenance. As the temperature rises the air conditioning systems run more often which means they pull in more air and particulate that will clog the filters and lead to reliability problems in the compressor. This compressor is subjected to more of a work load in the summer and more airflow restriction, if the filters are not changed often. This may lead to more air condition filters during the summer months.
EXAIR compressed air operated Cabinet Coolers System are a great solution for cooling enclosures. They operated via vortex cooling which requires no moving parts or filters from the outside air. They drop your compressed air temperature 50 degrees Fahrenheit. Mounting requires a compressed air supply, a standard electrical knockout, and the locknut that comes with the Cabinet Cooler System. The cooling is produced immediately with no lag time. A Electronic temperature controller is a available to maintain a temperature of your choosing.
Cabinet Cooler Systems are maintenance free with a clean dry supply of compressed air. Recently, we tested a cabinet cooler that was over twenty years old that still tested to our production standard. The customer was delighted to hear that is was working so well they wanted it returned. Cabinet Cooler Systems are available for NEMA 12, NEMA 4 and NEMA 4X enclosures. Kits include compressed air filtration to keep water, dirt and oil out of your enclosure. If you see an open panel door this summer, look into a Cabinet Cooler Systems. We can help you beat the heat.
EXAIR’s Cabinet Coolers are in stock and ready to ship to you same day if ordered by 3:00 pm EDT. You can have it tomorrow if you like.
