What’s So Great About The New EXAIR Catalog #35?

This may seem biased, but my answer is, “EVERYTHING!” Now, that may SEEM biased, but consider the fact that, as an Application Engineer, I have a front row seat for the “Innovation Show” that is EXAIR. The attention to detail that gets paid to the design, testing, verification, and manufacturing of new products constantly reminds me that it’s a level of excellence that EXAIR’s founder, Roy Sweeney, instilled and promoted in our culture from when he started this business in 1983, until his passing in 2016. It’s a testament to his legacy that, not only does it continue; it shows no signs of slowing down. It’s that level of excellence that’s always made it easy for me to speak with confidence about the quality, performance, durability, and effectiveness of all of EXAIR’s engineered compressed air products.

Our Marketing folks proudly passed out copies of the new EXAIR Catalog #35 the other day, and I immediately started immersing myself in that pride as I thumbed through. I thought of 12 years (for me) worth of success stories in helping customers get the most out of their compressed air systems through the use of our products, and our expertise in not only those products’ implementation, but how they can best fit into those customers’ air systems, overall. I wasn’t too far in to my thumbing through, when the “new stuff” really started making an impression on me:

Ultrasonic Leak Detector: Model 9207 is the first new product you’ll see if you start at the beginning. It has the same functionality and tools (parabolic disc for finding out you have leaks in a particular area, and a tubular extension so you can track the leak to its exact location), and some nice upgrades: it’s powered by four AA batteries (instead of a 9V) and comes with a set of earbuds (which I personally prefer over the previous model’s earphones, which I always considered a compromise between headphone & earbuds, with the benefits of neither). It’s never been easier to find those costly leaks in your air system, and fix them.


1/2 NPT HollowStream Liquid Atomizing Spray Nozzles: We’ve had these in 1/4 and 3/8 NPT sizes for a while now, with the ability to spray up to 7.28 gallons per minute. The 1/2 NPT models almost double that capacity to a flow rate of 14 gallons per minute. These spray a ring of liquid, so their flow rates are lower than a comparably sized Full Stream Liquid Atomizing Spray Nozzle, which spray a full, filled-in circle.


Line Vac Conveyance Chart: Remember what I said above about the ability to speak confidently about our products? This new chart compiles decades of controlled in-house testing and details that some customers have shared with us on the performance of different Line Vac models with different materials they’ve been used to convey. While we can’t guarantee EXACT conveyance performance for any specific application, this is a VERY handy tool to get us “in the ballpark” and further increases our great ability to specify the right Air Operated Conveyor for your application.


ATEX Cabinet Cooler Systems: It was a pretty big deal when we introduced our HazLoc Cabinet Cooler Systems that are UL Classified for Class I Div 1, Class II Div 1, and Class III environments. And it WAS a big deal, in the United States & Canada. Now, we can offer the certification of hazardous location requirements, globally, for ATEX Zones 2 & 22. That’s ANOTHER big deal.


Speaking of big deals, come October, EXAIR will have been providing quiet, safe, and efficient compressed air products to industry for 40 years. Catalog 35 has all the products that we’ve been making since then, and everything we’ve added over the years. Click here to get one mailed out to you right away. If you’ve got questions about anything in our catalog, or how EXAIR can help you get the most out of your compressed air system, give me a call.

Class III Hazardous Locations Defined

The National Electrical Code (NEC) has a system for classifying areas deemed hazardous due to flammable or combustible materials. When an area is considered classified, extreme caution needs to be taken to ensure nothing within that area provides a possible ignition source. In the US, Underwriter’s Laboratory (UL) provides third-party certification for products that can safely be used in these areas. EXAIR’s newest addition to the longstanding line of Cabinet Coolers was our Hazardous Location Cabinet Cooler. Designed and built with these types of applications in mind, the Hazardous Location Cabinet Cooler has been independently certified by UL for use in Hazardous Locations in Class I Div 1, Groups A, B, C, and D; for use in Class II Div 1, Groups E, F, and G; and also in Class III areas.

Class III areas can often be overlooked as the materials that generally create a Class III area may not always be considered “explosive” by nature. In Class III areas, the risk of combustion occurs due to the presence of ignitable fibers or materials that produce or process combustible flyings. According to the International Electrotechnical Commission (IEC), combustible flyings are defined as solid particles, including fibers, where one dimension is greater than 500µ in size, which can form an explosive mixture with air at standard atmospheric pressure and temperature. These areas are most commonly found within the textile and woodworking industries. The video below, posted to YouTube by News Center Maine, shows just how violent an explosion due to wood fibers can be:

When using a Hazardous Location Cabinet Cooler in a Class III area, it’s important to keep the Cabinet Cooler and immediately surrounding area free of settling debris. Implement a regular inspection, and cleaning procedure if necessary, to ensure that the flyings/textiles don’t accumulate on the Cabinet Cooler.

If you have control panels installed in a hazardous location and are sick of the nonstop maintenance associated with an A/C type system, the Hazardous Location Cabinet Cooler is the right tool for you.

Hazardous Location Cabinet Coolers

Last year was a big year for EXAIR’s Cabinet Cooling product line, in November  we launched our first Hazardous Location Cabinet CoolersEXAIR has always been a leading supplier in compressed air-based Cabinet Coolers, now we have expanded on that to work in the most high-risk conditions.

When a Hazardous Location Cabinet Cooler is used in conjunction with a purge system, they will keep electrical equipment at the desired operating temperature to protect and lengthen the lifetime of pricey controls and power supplies.

Hazardous Location Cabinet Cooler

 

Electrical equipment can cause explosions in certain atmospheres. Equipment used in areas where explosive concentrations of dusts or vapors may exist must be equipped with special wiring and other electrical components for safety purposes. Hazardous (classified) locations such as these might exist in aircraft hangars, gasoline stations, paint-finishing locations or grain bins. EXAIR’s Hazardous Location Cabinet Coolers have been approved and tested by UL for use in the following areas:

classified_cULus_360x283
UL Approved and Tested

Class I Div 1&2 – Groups A, B, C, and D

  • Class I Areas refer to the presence of flammable gases or vapors in quantities sufficient to produce explosive or ignitable mixtures. Class I Div 1 will have ignitable concentrations of flammable gases present during the course of normal operations. This is level of approval is one that differentiates the EXAIR Hazardous Location Cabinet Coolers from much of the competition. Class 1 Div 2 areas will have flammable gasses or vapors present only in the event of an accident or during unusual operating conditions.

Class II Div 1&2 – Groups E, F, and G

  • Class II areas are locations in which combustible dust may exist. The end user shall avoid installation of the device in a Class II environment where dust may be readily disturbed from the exhausts of the Hazardous Location Cabinet Cooler. Any dust formed in the vicinity of the cooler must be cleaned regularly.

Class III

  • Class III areas are locations that will have ignitable fibers or flyings present. This is common within the textile industry.

The Cabinet Cooler also carries a temperature rating of T3C, meaning it cannot be installed near any materials that could auto-ignite at temperatures in excess of 320°F.

The Hazardous Location Cabinet Cooler is available in (8) different cooling capacities ranging from 1,000 Btu/hr – 5,600 Btu/hr. The Cabinet Cooler is the best solution for protecting your sensitive electronics from heat, dirt, and moisture. With Nema 4/4X systems available, the Hazardous Location Cabinet Coolers will keep the cabinet cool without compromising the integrity of the enclosure.

If you’ve got an electrical cabinet installed within a hazardous location, fill out the Cabinet Cooler Sizing Guide and allow an EXAIR Application Engineer to determine the most suitable model for you.
