Last week, a customer called in to talk about their application. After aluminum and steel machining operations, parts are run through a washer system. The drying portion utilized a Super Air Amplifier to dry the sides and a Super Air Knife to dry off the top. The wash temperature was running at 185°F. The customer wanted to review the application and make sure the EXAIR products utilized in the process were rated to this temperature and to check on high the products could go, since the maximum possible temperature for the washer was listed as 250 °F.
The Super Air Amplifier is rated to 275°, above the maximum possible condition. The Super Air Knife was pre-installed with a stainless steel shim, enabling a maximum temperature rating of 400 °F. Both of the components are rated for temperatures in excess of the maximum possible washer temperature condition, and the customer felt confident with the system design.
EXAIR has several options in the Air Amplifier and Super Air Knife product families to allow for operation in high temperature applications. For the Air Amplifier, the Super Air Amplifier and Aluminum Adjustable Air Amplifier have a maximum temperature rating of 275°F. The Stainless Steel Adjustable Air Amplifier is rated to 400°F, and for the hottest of conditions, the High Temperature Air Amplifier is rated to 700°F.
Relating to Super Air Knife, the aluminum Super Air Knife is rated to 180°F. With a stainless steel shim installed, the maximum increases to 400°F. The PVDF Super Air Knife, used in applications where chemical resistance is needed, can withstand temperatures up to 275°F. And for the most extreme temperature environments, the Type 303 and Type 316 Stainless Steel Super Air Knives are rated up to 800°F.
To discuss your application and how an Air Amplifier and Super Air Knife or any EXAIR Intelligent Compressed Air Product can help your process, feel free to contact EXAIR and one of our Application Engineers can help you determine the best solution.
I recently had a customer call in that was trying to boost an exhaust on a hot operation that he had in his facility. We discussed what kind of fumes he was trying to evacuate and it appeared at face value that a High Temp Air Amplifier would be the perfect solution for his application.
Then the words that strike fear into some manufacturers came out. The customer asks, do you have any way to put a 4 bolt flange onto the unit so I can mount it straight into my piping system? My response, “All I need are the dimensions of the flange you need and we will see what is possible.” After a few further questions and verification, we had a drawing with dimensions of a Flanged High Temp Air Amplifier. We sent the drawing to the customer for approval, and once approved, we began to manufacture the custom product and provided it to the customer. This unit will allow the customer to easily boost the exhaust on his operation and will bolt straight into his piping so there are no worries on his end about exhaust gas escaping. His 500°F air temperature of the gases are of no concern to this special as it carries with it the high temperature rating of 700°F. The pictures below show the Special – Flanged High Temp Air Amplifier.
If you think there is no way we can find a product that will fit your compressed air application, or adapt a product to fit then give us a call, you might just be surprised at what we can offer in a quick turn around.
As the weather starts to warm up we have already started getting calls about customers that are preparing for Summer time by installing Cabinet Cooler Systems on their enclosures. This is not a lengthy process, in fact, we can hold races in the office to see who can do the calculations the fastest. If we have a few simple pieces of information, we can even do the calculations and have a recommendation for the correct Cabinet Cooler System for your cabinet while you are on the phone with us. What kind of information might we need you ask, just take a look at the Cabinet Cooler Sizing Guide below. The only tools you will need are a tape measure and a thermometer.
So what happens if your ambient external air temperature is above 125°F? For EXAIR, that is not a problem. We offer a full line of High Temperature Cabinet Cooler Systems. These are ideal for those really hot environments that may be near a furnace, boiler, or other hot process. The best part is, we will know whether this is needed without you even having to ask for it. All we need is the information on the Sizing Guide.
Whether your enclosure is in an everyday machine shop, out building with pumps and sensors, or right next to a steel mill, EXAIR will provide the best possible solution to keep the internals safe. Don’t let the summertime heat sneak up on you and cause you problems all you have to do is contact myself, or any one of my team members and we will help as quickly as possible.
As I scanned through my emails this morning in search for a Cabinet Cooler Sizing Guide sent to me back in June (some changes were made by the end user and I wanted to reference the original heat load), I noticed the large number of sizing requests typical of summer months. When I clicked back to my inbox I saw four more Cabinet Cooler sizing requests awaiting me from different corners of the globe.
One that stood out to me was in a particularly hot environment (Approximately 180 degrees Fahrenheit), and needed NEMA 4X protection. The end user was kind enough to send a sketch of the enclosure they plan to use, and needed to know if an EXAIR NEMA 4X Cabinet Cooler could work for their application.
Fortunately for the end user, our Cabinet Coolers are suitable for many types of enclosures, and we have a staff of Application Engineers on hand to sort through any abnormalities or questions which may arise. So, we are able to say with certainty that our Cabinet Cooler can work in their application.
Another fortunate feature for this end user is that EXAIR manufactures High Temperature Cabinet Coolers available from stock, and suitable for temperatures up to 200 degrees F. These high temp systems are perfect for metallurgical plants, use near ovens or furnaces, and for applications with higher than normal compressed air temperature.
If the specifics of your application raise any doubt about integrating an EXAIR Cabinet Cooler, contact an EXAIR Application Engineer.
I was working with a customer recently who had a fairly interesting application that I’d like to share with you. The customer operates a steel furnace and they have an automatic, liquid steel temperature probe that does not have sufficient time to cool down before they take another temperature measurement which should be a minimum of 5 minutes.
The probe consists of a 6 foot long, ¾” pipe, attached to the end of a 12 foot long beam. The beam lowers the pipe with the probe attached into the steel bath to take the temperature (see sketch below). The pipe is covered with a consumable, cardboard type of tube (pictured above) which is the thermocouple. A contact block with wiring inside the pipe connects to the thermocouple. This contact block becomes heat damaged because the pipe does not have enough time to cool between temperature measurements.
The customer was originally thinking about using a Super Air Knife to cool the probe and pipe between temperature measurements. After discussing options, the customer took our advice and went with (2) of our 2” Stainless Steel Adjustable Air Amplifiers (model 6042) instead. The Air Amplifiers are able to be mounted at the “parked” position of the pipe / probe and actuated to blow down the pipe and thermocouple length-wise during this time.
The high velocity airflow was able to carry enough heat out of the assembly between temperature measurements that the contact block was no longer becoming overheated and damaged as it was before. We decided to suggest this option to the customer because the air usage for this option was less than that of a 60” long Air Knife and the Stainless Adjustable Air Amplifier has temperature rating of 400°F which was easily able to withstand the heat in the application.
