Happy New Year, everyone! I hope your 2009 is starting off well.
Unfortunately, some of the customers I have talked to this week are not having the best start to 2009. So, they contacted us for help. Believe it or not, even in the dead of winter, electrical control panel overheating is still a problem. Leaving doors open, using dust-clogged small cooling fans, or using ineffective, always breaking down AC units just aren’t cutting it. The heat being produced by the equipment inside is still too much, and failure or shutdown is just a matter of time. But, that’s where we come in.
Our Cabinet Coolers run on compressed air, and can replace the above mentioned inferior methods. All our units are rated at least Nema 12, so when you close the doors, they will keep airborne dust and debris out of the cabinet, while also providing cooling.
You can also throw away that barely-working, dust-coated small fan and seal up the opening it was in. When used on a sealed cabinet, our units will maintain about 45% relative humidity inside the enclosure, and will thus prevent condensation issues that can be caused by the fan bringing in warmer, more humid ambient air.
If your cabinet currently has a functioning AC unit, you may ask, why would I switch now? The short answer is, you certainly don’t have to. The longer answer explains why you will be better off in the long run if you do. Our Cabinet Coolers are quieter, smaller, and much less cumbersome, to start with. They also have no moving parts, which leads to a much longer useful life, and zero maintenance down time. The only care the Cabinet Cooler needs is to be sure that it is supplied with clean, dry, oil free air.
Although the Cabinet Cooler does not require electricity to function properly, if you are worried about compressed air consumption, you may consider incorporating a thermostat and solenoid valve so that air is only being used when needed. You can “set it and forget it”, as a famous infomercialist once said. The air will turn on and off as the internal temperature changes. If you are one of those lucky folks who only has an intermittent heat problem in the summer, then this would certainly be the way to go for you. You could set the unit up now, before the heat problems begin, and you may not hear the unit kick on until May or June.
If any of these above situations rings true for you, now is the time to start thinking of a better way of cooling your electrical equipment, before the heat problems rear their ugly heads yet again. If you want to explore the compressed air Cabinet Cooler option further, please contact us.
