New Press Release: Aluminum ATEX Cabinet Cooler Systems

Published on by Russ BowmanLeave a comment

EXAIR Cabinet Cooler Systems have been providing durable and reliable heat protection for electrical & electronic panels for decades. With no moving parts to wear or electrical components to burn out, as long as you supply them with clean, moisture-free compressed air, they’ll operate darn near indefinitely, maintenance free.

Among the options we’ve offered with our Cabinet Cooler Systems are:

  • Three levels of NEMA integrity to suit the environment it’ll be installed in:
    • NEMA 12 (dust tight, oil tight, indoor duty)-for general industrial environments where no liquids or corrosives are present.
    • NEMA 4 (dust-tight, oil-tight, splash-resistant, indoor/outdoor duty)-for wash down areas, outdoor installations, etc. Basically, anywhere the panel could get wet.
    • NEMA 4X (dust-tight, oil-tight, splash-resistant, corrosion-resistant, indoor/outdoor duty)-for NEMA 4 environments where the panel is also exposed to corrosive elements. These are also popular (and oftentimes specified) in food and pharmaceutical uses. We offer them in either 303SS or 316SS.
  • Thermostat Control:
    • Our standard offering is a bimetallic probe thermostat, preset to 95°F (35°C) that gets wired in to the ‘hot’ lead of the Solenoid Valve, which gets plumbed to the compressed air supply line. We have 120VAC, 240VAC, and 24VDC Solenoid Valves.
    • ETC Electronic Temperature Control is a digital system with an LED readout for continuous display of the panel’s internal temperature, and the ability to change the temperature setpoint via push button control. ETC systems come in 120VAC and 240VAC configurations.
  • High Temperature Cabinet Cooler Systems. These are rated for use at ambient temperatures from 125°F to 200°F (52°C to 93°C).
  • Non-Hazardous Purge (NHP) Systems. These are Thermostat controlled, but they provide a slight positive pressure in the enclosure even when the Solenoid Valve is closed. They’re particularly well-suited for dirty environments where contamination could enter through small holes, conduits, etc. that cannot be positively sealed.

Over the last few years, we’ve also offered the NEMA 4 & 4X Cabinet Cooler Systems for UL Classified areas. Our HazLoc Cabinet Cooler Systems are rated for Class I Div 1, Class II Div 1, and Class III areas, and they meet the safety standards published by UL in the United States and Canada.

Our latest offering for hazardous locations is our ATEX Cabinet Cooler Systems. ATEX (an initialization of the French term “ATmosphères EXplosives” (explosive atmospheres) refers to a directive by the European Union aimed at safety in such environments. This month’s EXAIR Press Release details our Aluminum ATEX Cabinet Cooler Systems:

NEMA 4 ATEX Cabinet Cooler System safely cools a panel in a Zone 2 (explosive vapor) area of a battery plant.

Hazardous Location Classifications Explained: HazLoc Cabinet Cooler

Published on by Tyler DanielLeave a comment

As we approach the hot, humid summer temperatures across much of the USA, it’s important to begin considering a solution for your control panels. This is even more critical in facilities that handle hazardous or combustible materials or chemicals. A common solution for panel cooling is to simply install a couple of fans: one to draw in fresh ambient air and a second to exhaust warm air from the panel.

While this might work in some cases, it is most definitely unsuitable for use in an area where there’s exposure to anything flammable or combustible. The fan would simply draw those vapors in and pass them into the panel where it’ll create a quick ignition source.

EXAIR’s Hazardous Location Cabinet Coolers are engineered for use with purged (not included) electrical enclosures. The HazLoc Cabinet Coolers are not purged and pressurized control systems and should not be relied upon nor used in place of a purged and pressurized controller. They are a cooling solution meant to be used in conjunction with a purged and pressurized control system. These systems have been approved and tested by UL for use in the following areas:

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. For a comprehensive list and description of all the various Classified areas, check out the UL website.

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 in a hazardous location, fill out the Cabinet Cooler Sizing Guide and allow an EXAIR Application Engineer to determine the most suitable model for you. Don’t let the heat get the best of you this summer!

Please Wait For The Automated Attendant….

Published on by Brian FarnoLeave a comment

When you call a company to look for help, do you really want to have to dial a person’s name like you are on your old Nokia phone using the T9 keyboard, or do you want to hear a real person’s voice? (It’s okay if you are googling T9, I did it for you, and the best results are shown in the image below.)

Google results for T9 texting. My favorite part is the Reddit link on the right. r/dumbphones.

My answer is to speak to a real person. This is something I have always appreciated whenever I contact a company, whether it be to try and get information from them or to give information to them about EXAIR products. I understand that in some companies it helps with efficiencies and keeps cold-calling salespeople at bay (at least the ones that take no as the first answer). Yeah, automated systems may help reduce distractions for those who answer the phone, but at the same time, they may hinder someone who is trying to get a quick answer and wants to place an order.

Well, here at EXAIR, you don’t need to know how to spell names on your Nokia phone that you just racked up a high-scoring game of Snake on. Instead, you get a person who is a member of our Order Entry Team. They can actually help you submit orders, give chip estimates, product pricing, and even some lead times on stock products. Then, if you have technical questions or need something outside of that, they can bounce you over to us, the Application Engineering team. There’s a good chance you will hear less of our hold music than a full song or advertisement.

We will help you from there on out, even if it means placing an order. We not only try to be your one-stop shop for industrial compressed air products, but we also strive to be easy to do business with and get you the answers you need when you need them, not suspend you in a loop with our automated phone attendant until you discover the secret code to get to a real human.

If you have questions about EXAIR products or industrial compressed air processes, please contact an Application Engineer today.
