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.

From right to left: Small NEMA 12, Large NEMA 12, Large NEMA 4X

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.

NEW PRODUCT:  Protect Sensitive Electronics in Explosive Environments with New Aluminum ATEX Cabinet Cooler Systems

            EXAIR’s ATEX Cabinet Cooler® Systems deliver a powerful and affordable solution for keeping electrical enclosures cool in hazardous ATEX classified areas—and they’re now available in durable aluminum construction. Engineered for use in Zones 2 and 22, these coolers are UL-tested, CE compliant, and meet stringent ATEX standards for purged and pressurized enclosures.

            With cooling capacities of up to 5,600 Btu/Hr., ATEX Cabinet Coolers are ideal for preventing overheating in electrical cabinets exposed to explosive atmospheres. Whether you’re dealing with industrial control panels, application-specific electrical boxes, or simply sensitive electronics in hazardous locations, these systems ensure your equipment stays cool, safe and operational. Designed for quick and easy installation, the ATEX Cabinet Cooler mounts through a standard electrical knockout and maintains NEMA 4 integrity even in demanding environments. Optional thermostat controls reduce compressed air usage, while cold air distribution kits ensure even cooling throughout the cabinet.

            EXAIR offers a comprehensive lineup of Cabinet Cooler Systems for NEMA 12, 4, 4X, hazardous location and ATEX applications. Built with no moving parts, every system is CE compliant, UL-listed, and designed for long-term reliability in the most challenging conditions.

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!

From the Optimization product line, EXAIR’s Electronic Flow Control and the Electronic Temperature Control meet the low voltage standards of EU Low Voltage Directive (2006/95/EC). A CE label is placed on all products that comply with applicable directives.

A more recent edition to the EXAIR line of Cabinet Coolers has been our UL HazLoc and ATEX lines for maintaining safe operating temperatures for control panels in hazardous areas or ATEX Zones. In these spaces, it’s critical to have a product that’s designed for safe operation to alleviate any risks for fire or explosion due to combustible materials or vapors that may be in the atmosphere.

In the assembly of electrical products there can be hazardous materials used during production. The Restriction of Hazardous Substances, also known as RoHS or (2002/95/EC), restricts the use of materials such as: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates. The electrical portions of EXAIR’s Static Eliminators, Electronic Flow Control, Electronic Temperature Control, Digital Flowmeter, solenoid valves, and thermostats all comply with the amendment outlined in the European Commission decision L 214/65.

EXAIR is also committed to providing products that are conflict mineral free. In support of Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, EXAIR complies with the conflict minerals rule to curb illicit trade of tin, tantalum, tungsten and gold in the DRC region. Using the CMRT 4.20 template, we’re able to document our supply chain to ensure our materials are not being sourced from places that could finance conflict in the DRC and surrounding countries.

According to regulation (EC) No 1907/2006 Title I, Article 3, paragraph 3, the European Union enacted legislation requiring substances and chemicals imported into the EU to be registered to ensure a high level of protection for human health and the environment. Per Title II, Article 7, paragraph 1, articles must be registered when a substance is intended to be released during normal conditions of use that would exceed 1 metric ton per producer per year. Since EXAIR products do not contain substances that are intentionally released, registration is not required.

If you’re looking to maintain compliance in your industry, EXAIR products have you covered. If you have any questions about these standards of compliance feel free to reach out to us. Our team of Application Engineers have years of experience in industry and are waiting to take your call.
