This past Monday, we kicked off the start to the new Spring season, which means warmer temperatures are in the forecast. Here in Cincinnati, we are expecting temps in the low 40’s up to the high 60’s. We’ve written a couple blogs in the past few weeks about the changes in temps and weather and the proverbial “spring cleaning” and the use of our Vacuum Systems for industrial cleanup.
Another area of concern relating to the increased temps is the overheating and contamination of electrical control panels in industrial environments. As the temperatures go up, many companies are looking for a fast solution and will open the doors on the panel and use a fan to blow air across the sensitive controls. While this method does provide some cooling and seems like a quick fix, you are also introducing dirty, potentially humid air into the enclosure which can result in failures and lost production. Not to mention, this is an OSHA violation which can lead to potential injury to operators and/or costly fines.
EXAIR’s Cabinet Coolers are a reliable, maintenance free way to keep electrical enclosures cool, dry and clean. The Cabinet Coolers are compressed air operated, with cooling capacities ranging from 275 Btu/hr. up to our largest Dual System of 5,600 Btu/hr. The units discharge the cold air into the cabinet at a slight positive pressure which expels the hot, dirty air, leaving only the cool, clean, dry air from the system. Systems are available for continuous operation, maintaining a 45% relative humidity on a completely sealed cabinet, ensuring no condensation develops inside the cabinet. Our Thermostat Controlled Systems are available in 120VAC, 240VAC or 24VDC, providing a more economical operation by only using compressed air when needed to reach the desired temperature set point. Our thermostats are preset at the factory to 95°F but are adjustable to meet your specific temperature requirement.
In order to properly recommend a unit, we need to know the internal heat load of the cabinet or watt loss of the controls inside. We realize this information is sometimes not readily available, so to help simplify the process, we have a Sizing Guide available, which provides the pertinent information requited to calculate the current load. Of course, you can always give us a call and an application engineer can help you over the phone as well.
