EXAIR’s Cabinet Coolers Meet Specific Environmental Needs

I wrote recently about a “textbook” application for EXAIR Cabinet Cooler Systems…overheating control cabinets on a factory floor, solved quickly & easily with stock product, off the shelf, installed in minutes.

“Well, la-di-da, Russ,” some may say, “You sure knocked that whiffleball out of the park, didn’t you? What about those of us with more complex requirements than a plain Jane electric box on a typical production floor?”

To them, I would say:

1. Yes we did, and thank you for noticing!
And
2. Read on.

EXAIR manufactures, and stocks, a number of special Cabinet Cooler Systems to meet most any need:

Food and pharmaceutical processing areas often call for specific materials of construction. Something that doesn’t corrode, something that isn’t susceptible to surface wear or pitting in a washdown environment…something like Type 316 Stainless Steel. For these cases, we also offer our complete line of NEMA 4X Cabinet Cooler Systems in optional 316SS construction, from 275 Btu/hr (69 Kcal/hr) to 5,600 Btu/hr (1,411 Kcal/hr.) And they’re all in stock.

Of course, other harsh environments, like this outdoor installation at a wastewater treatment plant, also require the highly corrosion resistant properties of 316SS.

EXAIR Cabinet Cooler Systems work best on a sealed enclosure, but sometimes it’s not feasible to completely seal an enclosure – there may be a cable bundle coming through a common penetration, or perhaps the door isn’t fitted with a gasket.  In cases where such equipment still needs to be protected from dust, fumes, or other environmental contaminants, you could always use a Continuous Operation Cabinet Cooler System.  But, if you want to control operating costs with Thermostat Control, our Non-Hazardous Purge option provides a continuous positive flow, even when the internal temperature is below the Thermostat setpoint, to prevent these contaminants from entering.  These are all in stock as well.

Non-Hazardous Purge option is available for any EXAIR Cabinet Cooler System.

When we calculate heat load, we use your Sizing Guide data to determine both internal heat load (generated by the components in the enclosure) and external heat load (generated by the ambient temperature in the area.)  Regardless of the internal heat load, enclosures in extremely hot locations need protection too.  When the ambient temperature will exceed 125°F, a High Temperature Cabinet Cooler System is specified…performance is identical, but they’re outfitted to withstand the higher temperatures for durability and long lasting operation.  This option is offered for all of our Cabinet Cooler Systems 1,000 Btu/hr and higher, and they are also all in stock.

This Dual Cabinet Cooler System protects a critical equipment panel on a hot roll steel line.

No matter the challenges of your facility’s environment, we can help.  Again…all of the above options are in stock, ready for immediate shipment.  What could be better?

Well, actually, we ARE giving away free stuff with Cabinet Cooler System orders through the end of July 2018:

This applies to our standard Cabinet Cooler Systems, as well as those with options for various environmental considerations detailed above.

So…don’t overheat your electronics from the inside, or out, wherever they’re located.  If you’d like to find out more, give me a call.

EXAIR’s Cabinet Coolers Solve Your Overheating Problems

We here at EXAIR always know when summer is approaching, as phone calls and orders for the Cabinet Cooler Systems start to kick into high gear.  After those first few hot days in late spring, it is common for panels and electrical enclosures to overheat due to faulty air conditioning units, fans that are not working, or lack of a cooling system in general.

Time for us to sharpen our pencils and be ready to help! Our Cabinet Coolers are in stock and ready to solve your overheating problems with same day shipping on orders we receive by 3pm. If you need assistance choosing your Cabinet Cooler Solution, Contact an Application Engineer today!

The Cabinet Cooler System is a low cost, reliable way to cool and purge electronic control panels.  We recently hosted a Webinar on the systems, and it is available for review (click picture below)  webinar-on-demand

EXAIR Cabinet Coolers incorporate the vortex tube technology to produce cold air from compressed air, all with no moving parts.

Below shows the basics of how the Cabinet Cooler is able to provide cooling to an enclosure.  Compressed air enters the vortex tube based system, and (2) streams of air are created, one hot and one cold. The hot air is muffled and exhausted through the vortex tube exhaust.  The cold air is discharged into the cabinet through the Cold Air Distribution Kit and routed throughout the enclosure. The cold air absorbs heat from the cabinet, and the hotter air rises to the top of the cabinet where it exits to atmosphere under a slight pressure. Only the cool, clean, dry air enters the cabinet – no dirty, hot humid outside air is ever allowed into the cabinet!

HowCCWorks
How the EXAIR Cabinet Cooler System Works

EXAIR offers Cabinet Cooler Systems for cabinets and enclosures to maintain a NEMA rating of NEMA 12 (dust tight, oil-tight), NEMA 4 (dust tight, oil-tight, splash resistant, indoor/outdoor service) and NEMA 4X (same as NEMA 4, but constructed of stainless steel for food service and corrosive environments.

Cabinet Cooler Systems can be configured to run in a Continuous Operation or with Thermostat control. Thermostat control is the most efficient way to operate a Cabinet Cooler.  They save air by activating the cooler only when the internal temperature reaches the preset level, and are the best option when fluctuating heat loads are caused by environmental or seasonal changes. The thermostat is preset at 95°F (35°C) and is easily adjusted.

Another option is the ETC Electronic Temperature Control, a digital temperature control unit for precise setting and monitoring of enclosure conditions. An LED readout displays the internal temperature, and the use of quick response thermocouple provides real time, accurate measurements. The controller has easy to use buttons to raise or lower the desired cabinet temperature set-point.

Other Special Cabinet Cooler considerations are:

  • High Temperature –  for ambient temperatures of 125°F to 200 °F – for use near furnaces, ovens, etc.
  • Non-Hazardous Purge – ideal for dirty areas where contaminants might normally pass through small holes or conduits. A small amount of air (1 SCFM) is passed through the cooler when the solenoid is in the closed position, providing a slight positive pressure within the cabinet.
  • Type 316 Stainless Steel – suitable for food service, pharmaceutical, and harsh and corrosive environments.

If you have any questions about Cabinet Coolers or any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

EXAIR’s Cabinet Coolers Eliminates Worry of Shutdowns

316SS Electrical Panels

A food and beverage company had 316SS NEMA 4X (IP66) electrical panels inside their facility.  The reason for the stainless-steel construction and NEMA 4X or IP66 rating was for the periodic washdowns with an aggressive cleaner.

This particular company had a bottling process and inside each panel, sensitive electrical components would control the operation of the system.  The panels were fitted with Freon type air conditioners to keep the electrical components cool.  One day, they had an A/C unit that failed, and it shut down their system for half a day.  For a bottling company, a shutdown for this long stopped many bottles from being processed which costed much money from loss of production.

They had four panels that were setup similar right next to each other.  They were fitted with 1,700 BTU/hr freon system on each panel.  In this situation, one of the refrigerant compressors failed.  They had to hire a mechanical serviceman with a license to work on Freon systems.  Because of the length of time to get their system restarted, they were losing money every minute.  This emergency call really hindered the entire bottling process.  In fear of another shutdown, they contacted EXAIR to see if we could help them.

Even with constant maintenance, the life span of a Freon system is only around five years.  (It can be even shorter if preventative maintenance is not scheduled regularly). Any mechanical system with moving parts will wear out and fail.  EXAIR Cabinet Coolers use the power of a Vortex Tube which only needs compressed air to generate cold air.  With no moving parts to wear or unsafe Freon to leak, they are designed to keep your electrical components cool and operating for a very long time.  Trying to predict failures with refrigerant systems is very difficult to determine; but, with the EXAIR Cabinet Cooler Systems, it takes that worry away.

EXAIR NEMA Type 4X Cabinet Cooler System

EXAIR Cabinet Cooler Systems are manufactured in a variety of options and types to meet different application requirements.  For the food and beverage company above, I recommended the model 4830SS-316 Cabinet Cooler System to replace each of the A/C refrigeration systems.  The model 4830SS-316 would meet the cooling requirement with 2,000 BTU/hr capacity, the NEMA 4X (IP66) rating of the panel, and the 316SS construction to withstand washdowns.  The complete system includes the Cabinet Cooler, a filter, cold air distribution kit, a thermostat and a solenoid valve.  The thermostat is preset at 95 deg. F (35 deg. C), and it operates a solenoid valve to only turn on when cooling is needed.  EXAIR has this model in stock as well as many others for quick delivery, reducing any downtime.  After the installation of the Cabinet Coolers onto the panels, the worry of production stoppage due to a failure with an A/C system was alleviated.

Maintenance departments have many concerns in keeping a system running smoothly and uninterrupted.  Why add additional worries with coolant based panel coolers?  If you have electrical panels that can stop your operation like the bottling company above, an EXAIR Cabinet Cooler will be a reliable solution.  You can fill out the Cabinet Cooler Sizing Guide and an Application Engineer can determine the best model for you.

EXAIR’s Cabinet Coolers Provide Heat Protection 24/7

I had the pleasure of speaking with the Maintenance Manager at a manufacturing plant for a global automotive supplier earlier this week. They have a whole factory floor full of machinery that operates from PLC controls. The space is not climate controlled, and the temperature broke 100°F the day before. This triggered some high temperature warnings on several control panels, but that was the worst thing that happened…luckily.

It should go without saying that the automotive industry is a big deal in the United States…maybe even a bigger deal here in the Middle Atlantic region, and a HUGE deal for those of us within a few hour’s drive of Detroit, Michigan…the home of the Big Three.  Disruptions in their supply chains can affect not only the final production of automobiles, but also other suppliers, vendors, and service providers in separate “links” of that chain.  So, if my caller has a breakdown and can’t ship parts, many other suppliers’ lines may be slowed or stopped, because if Detroit can’t make cars without one supplier’s parts right now, they won’t need the others’ parts right now either.  That means reliability is paramount.

Even in extremely aggressive environments, an EXAIR Cabinet Cooler System is a durable, reliable heat protection solution for your sensitive electronics and controls.

This is a “textbook” situation for EXAIR Cabinet Cooler Systems.  They’re installed in minutes, have no moving parts, and require only a supply of compressed air for operation.  If that air is clean & dry, they’ll operate darn near indefinitely, maintenance free.  Thermostat Control turns them off & on as needed.  I’ve talked to more than a few users who were (pleasantly) surprised when a Cabinet Cooler System activated on the first hot day in the spring, after not seeing it come on at all, after that last hot day near the end of the previous summer.

Back to the situation at hand – the Maintenance Manager had gathered Sizing Guide data for a couple of enclosures.  You can submit it through our website, or email it in, but it only takes a minute; we do it over the phone all the time.  So I did, and quoted the appropriate Cabinet Cooler Systems, which were ordered soon after.  They were installed the next day, with a promise of more to come.

EXAIR Cabinet Cooler Systems are widely recognized as an ideal solution for electrical & electronic panel heat protection.

As if quick, easy, and reliable heat protection for sensitive and critical electronics isn’t enough, we’re sweetening the pot this summer:  order any EXAIR CAbinet Cooler System by July 31, 2018, and we will include a FREE AC Sensor, suitable for testing breakers, receptacles, switches, fuses, junction boxes, power cords – if it’s got (or should) have AC voltage going through it, the AC Sensor will light up and sound off (or not) to let you know for sure.

EXAIR’s Cabinet Cooler System is Durable and Reliable

Any realtor will tell you that the three most important factors in selecting a property are location, location, and location. This simply means that houses with similar features – number of bedrooms, yard size, structure, garage (or not,) basement or not,) etc. – can be found in a lot of very different neighborhoods. Whether you want to live somewhere that’s convenient to the highway, close to (or not so close to) work, near your favorite activities, etc., odds are you can find a house that meets your material needs & wants within those geographical confines. Hence, location is your #1 consideration. And your #2 and your #3 as well…my lovely bride is a real estate professional, so I have this on good authority. And, so you know, #4 is price, and #5 is condition.

Electrical and electronics controls professionals will tell you that three of the most important things to protect their equipment from are heat, moisture, and dust. If you’re looking for a durable, reliable, and low cost method for that, we’ve got the solution: the EXAIR Cabinet Cooler System. Selection of the right system comes down to determining your heat load, and…the reason for today’s blog…the LOCATION in which it will be installed.

Let’s say it’s a control panel for one of the machines on a factory production line…indoors & dry.  Our NEMA 12 Cabinet Cooler Systems provide protection against dust and oil from entering the enclosure.

NEMA 12 Cabinet Cooler Systems are oil tight, dust tight, and rated for indoor duty. They can also be installed to the wall of an enclosure (instead of the top) with a Side Mount Kit.

If the enclosure is outdoors, or indoors but subject to water spray (like in a wash-down area,) our NEMA 4 Cabinet Cooler Systems are oil tight, dust tight, AND splash resistant.  They ensure the inside of the enclosure stays dry through the use of a low pressure relief valve that seals when the cooler is not operating, maintaining NEMA 4 integrity at all times.

EXAIR NEMA Cabinet Cooler Systems provide additional protection to keep the enclosure dry inside.

Our NEMA 4X Cabinet Cooler Systems are made of stainless steel, and are commonly specified for food service area installations, and in corrosive environments.  They’re also oil tight, dust tight, and splash resistant.  These are also available in Type 316 Stainless Steel construction, for especially harsh conditions, or when this is otherwise specified due to the nature of the installation, such as critical food grade or pharmaceutical areas.

EXAIR NEMA 4X Cabinet Cooler Systems are made of corrosion resistant stainless steel for corrosive environments, and are also available with Side Mount Kits.

Regardless of the NEMA rating called for by the location, all EXAIR Cabinet Cooler Systems are available with a Non-Hazardous Purge option, which provides a slight positive pressure through a low (1 SCFM) air flow when internal temperature is below the thermostat setpoint and the solenoid valve is closed.  This provides constant and reliable protection, even if the enclosure is not perfectly sealed, even in especially dirty or dusty environments.

All EXAIR Cabinet Cooler Systems are available with Non Hazardous Purge for constant, reliable protection from environmental contaminants.

High Temperature Cabinet Cooler Systems are also available when ambient temperatures can exceed 125F.  These are popular in foundries, glass production facilities, and even non-air conditioned spaces in particularly warm climates.

High Temperature Cabinet Cooler Systems provide reliable heat protection in areas where ambient temperatures reach 125-200F (52-93C)

If you’ve got sensitive, mission-critical electrical or electronic enclosures that need reliable heat protection, EXAIR has the solution you’re looking for.  If you know the required cooling capacity for your enclosure, you can select the right system directly from our website.  If you’d like help in calculating your heat load, you can use our Cabinet Cooler System Sizing Guide…just fill in the blanks and click “submit” – your request will be forwarded to an Application Engineer for immediate attention.  Or, if you’d rather, just give me a call.  We calculate heat loads over the phone all the time; it only takes a minute.
