With the stretch of hot weather we are having and the rain we got last week my garden at home is absolutely out of control. At least it was until I spent a good two to three hours picking weeds and grass out of the garden. This year we doubled the size of our garden from last year. When I did the garden last year I dug out most of the sod and it really helped cut down on the grass in the garden. When we expanded this year though I was just a little too busy to get the sod dug out and when a good friend tilled the garden for me he churned all the grass into the area. This was fine as he did it for free and I didn’t have to do it; but now I am paying for it. The grass that was in that area is now growing faster than anything else in my garden and was actually choking out all of the onions I had planted.
First I tried to quick fix problem by throwing more dirt over top of the grass to smother it. That worked for about a day. So I did what I had to do, I got in on my hands and knees and picked every little bit of grass out, roots and all. By the end of the next day the onions had all perked up, the tomatoes continued blooming and the zucchini look to be the first vegetable we will enjoy eating.
The fact of the matter is that I didn’t take time to make sure everything was in order before expanding the garden. I didn’t remove the sod, communicate that I preferred the sod out, or mention to my friend that if not removing the sod please chop it up well (a hard thing to state when your friend is doing you such a big favor). Because of that I had to dedicated a good part of my day at home working on a problem I could have prevented. The fact of the matter is a quick fix is just a temporary fix and it is only a matter of time before the real problem reappears and demands your attention.
The same can be said when you band aid an electrical cabinet that is overheating by opening the door and putting a fan in it. That doesn’t solve the problem, it may go away for a short moment, but then it will come back even worse. A fan will provide some temporary cooling but it will also deposit dirt and debris on to the electrical components (all that grime on the fan blades and guard is the same stuff being blown into your cabinet) which causes them to run hotter, short out, or burn. So instead of using a quick fix give us a call and let us help you determine the correct Cabinet Cooler System to cool your cabinet and get the problem solved the right way. The reality of installing a Cabinet Cooler is it takes a short amount of time and effort to install. If compared to other cooling alternatives it may be considered a quick fix – but one that lasts years, is low maintenance, and reliable.
From time to time we have customers call in and say “We have one of your products and need another. But we installed it so long ago that we no longer have the paperwork to know which model we bought.” That’s a great thing to hear in a way. Our products have outlasted their filing system, and not only that, but now we have potential to solve another problem for the same customer.
When this happens, we can sift through our files to find out which model was purchased, or if the original purchase was made through a third party, we can determine the model number in other ways. We can use the dimensions, material of construction, description over the phone, or a photo emailed to an Application Engineer such as the one below.
But, the needs of the application don’t end there. We may be able to pinpoint the model number of the device currently in use, but we also need to confirm that this model will be suitable for the new application. For the end user that sent in the photo above, this meant the completion of a Cabinet Cooler Sizing Guide for new heat load calculation.
What we determine in many cases is that the new application has specific needs which dictate the use of a product with different attributes (in this case a different Btu/Hr rating on a Cabinet Cooler). Whether it is because of heat load, ambient temperature concerns, required material, or any other variable, we are sure to provide the most suitable solution.
As spring gains momentum and warmer months are to come, it may be time to consider an EXAIR Cabinet Cooler solution for an overheating electrical panel in your facility. Contact an EXAIR Application Engineer for help calculating heat load and choosing the right system.
I recently spoke with one of my colleagues at our Finland distribution partner, Projecta Oy. He had an application for static elimination on a large paper producing machine. He has applied our Ion Bar to paper machines in the past to eliminate static. In this case though, the line speed was more than double that of his previous application at about 1450 meters per minute. He was not sure if he could apply EXAIR Static Eliminator to the affected machine or not, simply due to the line speed.
Actually, use of a Super Ion Air Knife, or rather a few of them (due to machine width) is right in line with what is recommended. When the application involves a high-speed, moving web there is the issue of a boundary layer of air that moves along adjacent to the web which can affect the static elimination result if not approached properly. The boundary layer can prevent static eliminating ions from reaching the surface of the statically charged web and must be overcome to be effective.
A Super Ion Air Knife, with it’s powerful laminar air flow, is the right choice on a web-based application like this one. Setting the unit up so that it blows parallel to the web but in the direction opposite the web travel creates a counter airflow which disrupts the boundary layer and allows the static eliminating ions to come into contact with the moving web to neutralize the charges present.
There is also a secondary benefit in that the Super Ion Air Knife, by being mounted in such a way, enables a much longer time in contact between the ions and the charged surface. This has the net effect of being able to reduce the static charge down to a much lower level before the web passes this area. Since slowing the web speed down is not an option in these cases, the only way you can effectively create dwell time within the ionized airflow is to extend the distance over which the web is treated and using the Super Ion Air Knives in this way allows the user to do that.
