Warmer temperatures are quickly approaching, which may seem like a welcome change for personal reasons, but in a processing line, the increased temperatures can wreak havoc on sensitive components found in an electrical control panel.
EXAIR Corporation will be hosting a FREE webinar titled “Intelligent Solutions for Electrical Enclosure Cooling” on May 23, 2018 at 2:00 PM EDT.
By attending this interactive session, you will learn the difference between the 3 most common NEMA ratings for electrical control panels found in an industrial setting, NEMA Type 12, 4 and 4X. We’ll provide examples of traditional, yet unreliable, methods of cooling and the concerns associated with using these types of devices.
Next we will explain how ignoring heat related issues can cause machines to shut down due to failed electrical components, resulting in lost production and increased maintenance costs, negatively affecting a company’s bottom line.
In closing, we’ll show how using an engineered, compressed air operated solution can reduce downtime by providing a low cost, maintenance-free way to cool and purge control panels with no moving parts.
There are many, many ways to cool something down. Which method works best will depend on a number of factors, but the biggies are:
*How hot is it? *How cool do you need it?
If you call EXAIR to discuss a cooling application, these are most likely the first questions that’ll be asked. And the answers will determine which product line we start talking about. In the title of this blog, I promised you two tales…here’s the first:
A caller from a metal fabricating shop needed to cool down metal cylinders after they were heated to 400F, and was curious to know if this was a good application for one of our products. Now, he had already answered one of our questions, so the answer to the second would tell the rest of the tale.
When I showed this to the caller, that was all the convincing it took…their goal was to reach 120F in about a minute and a half. Which, as you can see, will be no problem for the Super Air Knife.
Tale #2 is a bit different. This was from a firearms manufacturer who needed to cool small, but hot, parts quickly, and they needed to reach room temperature. Looking at the graph above, we know that blowing room temperature air on a hot part will cool it rapidly, until the temperature of the part begins to approach room temperature. The solution? Colder air, of course!
Enter the EXAIR Vortex Tube…after some discussion of the part size, shape, and their compressed air capacity, we determined the Model 3215 Medium Vortex Tube should be suitable for their operation. By generating a cold air flow of about 20F, this replicated the higher temperature differential we see in the left-hand side of the cooling graph above…where the cooling rate was the highest.
If you’d like to talk about how “cool” an EXAIR product can make your application, give me a call.
