Cabinet Cooler Systems For Specific Environmental Requirements

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 Cabinet Cooler Systems = Reliability

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.

If you have electrical or electronic equipment enclosures that need heat protection, EXAIR has the solution.  Call me.

Flat Super Air Nozzle: Build Your Own System Overview

Flat Nozzle Blow-off Kit

EXAIR manufactures a variety of nozzles that are OSHA safe, high quality, and very efficient.  In this blog, I would like to discuss the features and benefits of the EXAIR Flat Super Air Nozzles and how to build a system to fit your application.

The EXAIR Flat Super Air Nozzles are manufactured to blow a wide forceful stream of air.  Their patented design creates a high velocity, laminar air stream with minimal air consumption and low noise.  They come in two sizes; 1” (25mm) and 2” (51mm), and EXAIR stocks them in two different materials, zinc-aluminum alloy and 316 stainless steel.  With a metal construction, breakage is not a concern and performance is not sacrificed even in the harshest of environments.  I have seen many plastic flat nozzles that were broken in applications.  The noise level was loud, and compressed air was wasted.  The unique patented shims inside the EXAIR Flat Super Air Nozzles give three improvements to the design and function.   First, they come in different thicknesses to create a wide range of forces.  In conjunction with a regulator, you can “dial” in the correct amount of force from a breeze to a hurricane without overusing your air compressor.  The patented design also allows an even force across the entire width of the air nozzle.  Lastly, they help to entrain the free ambient air; so that less compressed air is required.  The high efficiency design will save you money.  The EXAIR Flat Super Air Nozzles are effective in uniform blowing; efficient; and superior in quality and durability.  You can watch a video blog on the importance of using our patented shim.

(Click on photo to go to blog)

To show the different types and styles of Flat Super Air Nozzles that EXAIR stocks, you can correspond to the model number make-up sheet below.

To give force adjustments to the individual Flat Super Air Nozzles, EXAIR offers a way to change the thickness of the shim to better suit your application.  You can increase or decrease the force of the nozzle by just removing two screws and changing the shim inside.  This is a unique feature as most competitive flat nozzles do not allow you to do this.  EXAIR offers different thicknesses of the patented shims in our Shim Sets.  The chart below corresponds the appropriate Shim Set to the Flat Super Air Nozzle.

Flat Super Air Nozzle to Shim Set Chart

What can make the Flat Super Air Nozzles even better?  More flexibility.  The Stay Set Hoses can add that flexibility to the Flat Super Air Nozzles.  They are designed to manually position the Flat Super Air Nozzle to accurately target the air stream.  They allow maneuverability to locate the nozzle at different heights or angles; and once positioned, the Stay Set Hose will hold the nozzle in place.  They come in different lengths from 6” (152mm) to 36” (914mm).  We carry two different styles of connections to adapt to any of the Flat Super Air Nozzles.  You can select the different lengths of Stay Set Hoses (SSH) to the Flat Super Air Nozzle by the model number make-up sheet below.

To build your system even further, EXAIR also can offer a Magnetic Base to your Stay Set Hoses and Flat Super Air Nozzles.  The Magnetic Base has a powerful magnet on the bottom to securely attach the blow-off nozzles vertically or horizontally.  This feature is great if you need to move the nozzles to different areas in your application.  EXAIR manufactures a one-outlet and a two-outlet design.  Each outlet has a ¼ turn valve to manually turn on or off the nozzle and only require one air supply inlet.  To add this product to the Flat Super Air Nozzle with the Stay Set Hose, you can use the model number make-up sheet below.

With the EXAIR Flat Super Air Nozzles, you can take advantage of the durability, safety, and efficiency for your blow-off device.  In addition, you can build a system that will best suit your requirements.  You can add different lengths of Stay Set Hoses and/or different Magnetic Bases.  With these combinations grouped into one model number and in stock for quick shipments, it makes it simple to purchase from EXAIR.  Just to let you know, they also come with a 30-day unconditional guarantee to try them out.  If you need any help in building your optimum blow-off system, you can speak to an Application Engineer at EXAIR.  They will be happy to assist you.

NEMA Ratings and Enclosure Locations

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.

Finding and Fixing Leaks in Your Compressed Air System

I had to find and fix some leaks this week – in my yard. See, my underground storm sewer pipe, that carries my basement sump pump discharge and my house’s gutter drains to the street, was leaking.

The evidence was clear…swampy puddles were developing in my neighbor’s yard.

The location was clear…several patches of grass in MY yard were WAY more green and vibrant than the rest.

The cause was NOT clear…until I dug up those patches of the best looking grass my lawn has ever seen. Turns out, my maple tree’s (the showpiece of my front yard) root system found a way to penetrate one of the couplings in the sewer pipe, where it prospered into this:

That’s about 8ft worth of root growth that was clogging my drain pipe, and causing leaks upstream. My maple tree is not shown in the picture because my maple tree is a real jerk.

Two days worth of digging up and reinstalling pipe later, and all is well.  I mean, except for filling the trench, sowing some new grass seed, watching the birds eat it, sowing some more, etc.  Ah, the joys of home ownership…

I tell you all this, dear reader, so you know that I. Don’t. Like. Leaks…whether they be in my storm sewer pipe or in your compressed air system…which brings me to the (real) subject of my blog today.

Unlike the visual indications of my yard leak, compressed air system leaks don’t really draw much attention to themselves.  Unless they grow quite large, they’re typically invisible and very quiet…much too quiet to be heard in a typical industrial environment, anyway.  Good news is, they’re not all that hard to find.

One way is to use a soap-and-water solution.  You just need a spray bottle, some dish soap, and water.  Spray it on the piping joints, and all but the smallest, most minute, of leaks will create soap bubbles…instant indication of air leakage.  This method is inexpensive and simple, but it does tend to leave little puddles all over.  Plus, if your header runs along the ceiling, you’re going to have to get up there to do it.  And unless you can easily maneuver all the way around the pipe, you can miss a leak on the other side of the joint. If you have a small and relatively simple compressed air system, and all your piping is accessible though, this method is tried and true.

For many industrial compressed air systems, though, the limitations of the soap bubble method make it impractical.  But I’ve got more good news: those silent (to us) air leaks are making a real racket, ultrasonically speaking.  And we’ve got something for that:

EXAIR Model 9061 Ultrasonic Leak Detector discovers and pinpoints leaks, quickly and easily.

See, when a pressurized gas finds its way through the narrow (and usually torturous) path out of a slightly loosened fitting, worn packing on a valve, etc., it creates sound waves.  Some of those ARE in audible frequencies, but they’re often so low as to be drowned out by everything else that’s happening in a typical industrial environment.  Those leaks, however, also create sound waves in ultrasonic frequencies…and EXAIR’s Ultrasonic Leak Detector takes advantage of that ultrasonic racket to show you where those leaks are, as well as give you a qualitative indication of their magnitude.  Here’s how it works:

Find leaks and fix them.  This is Step #2 of our Six Steps To Optimizing Your Compressed Air System.  If you’d like to find out more, give me a call.

1″ Flat Super Air Nozzle Makes Clean Sweep Of Greasy Chain

A manufacturer of lubrication equipment had a messy problem to solve with a customized system they were designing, to apply grease to a drive chain.  They wanted to clean excess grease off the chain and deposit it into a reclaiming chamber, both to keep the area clean, and to prevent waste.  And because of the corrosive nature of the environment, it had to be stainless steel.  This was a “textbook” application for our Model 1126SS 1″ 316SS Flat Super Air Nozzle.

 

EXAIR’s 1″ Flat Super Air Nozzle is available in Zinc Aluminum or 316SS Construction. The replaceable shim makes it one of our most versatile products.

They also needed to lock it into position, once the exact angle of the air flow was determined, so they incorporated a Model 9052 1/8 NPT SS Swivel Fitting into their design.

When supplied with a Swivel Fitting, the 1″ Flat Super Air Nozzle can be precisely aimed for the most exacting applications.

Now the chain is clean, the grease is reclaimed, and the simplicity of the operation drew a lot of positive attention from the client.

I’ve written about this before, but it bears repeating…EXAIR Corporation’s plan for success is centered on being easy to do business with.  This was a situation where every facet of the project was impacted by our commitment to that goal:

*The customer and I determined the correct product to try in just a few minutes on the phone.

*The order shipped out, same day.

*The attention to detail that Engineering and Production put into the development of this product became evident in the ease of installation and operation.

From the moment you contact EXAIR, to the moment you achieve success in your application, it’s our job to make sure you get the most out of our products. If you have a job that you think one of our products might be a good fit for, give me a call.

Liquid Handling With Compressed Air: An Overview

There are some very good reasons to consider an EXAIR compressed air operated Industrial Housekeeping Product for liquid applications:

*Durability. No moving parts means nothing to wear or get damaged.
*Safety. No electricity means no dragging an energized cord through a wet area.
*Convenience. All you need is a supply of compressed air.
*Reliability. If you supply it with clean, dry air, it’ll run darn near indefinitely, maintenance free.

Depending on the needs of the application, we have different models to choose from:

Reversible Drum Vacs

If you’ve got a closed top steel drum that’s in good condition, look no further than the Reversible Drum Vac System.  It comes with everything you need to turn that drum into a powerful, 2-way liquid pumping system.  This is great if you just need to park the drum in one spot and suction out a sump or tank on a regular basis, using its 10 foot Vacuum Hose & Suction Wand.  They’re in stock for your existing 30, 55, and 110 gallon drums.  A 5 Gallon Mini Reversible Drum Vac System is also available; it includes the drum as well.

Reversible Drum Vac Systems come in sizes from 5 to 110 gallons.

If you’d like a little mobility, and a way to clean up floor spills, then the Deluxe Reversible Drum Vac System might be what you’re looking for.  It adds a Drum Dolly and our Spill Recovery Kit…it consists of a floor-length wand and a dual squeegee tool.  It also comes with a set of plastic tools (crevice tool, small skimmer, and two 20″ extensions) and a Tool Holder with clips for the tools, and magnets to attach to the drum.  We keep them in stock for your existing 30 and 55 gallon drums.  It also comes in the 5 Gallon Deluxe Mini Reversible Drum Vac System (drum included.)

 

Deluxe Systems add a Spill Recovery Kit, and a Dolly for your drum.

For a complete system, the Premium Reversible Drum Vac Systems have everything you need for most any liquid drum transfer job: they add a drum, lid & latch ring, as well as a compressed air supply hose & shutoff valve, and an upgrade to Heavy Duty Aluminum Tools.  They’re available with 30, 55, or 110 gallon drums; in stock.

Premium Reversible Drum Vac Systems come with everything you need, right out of the box.

Any of the 30, 55, or 110 Gallon systems are also available with our High Lift Reversible Drum Vac.  These provide for increased performance with more viscous liquids, and/or when the liquid needs to pumped from a depth of up to 15 feet.  They are outfitted identically to the standard Reversible Drum Vac Systems, except they come with a 20 foot Vacuum Hose.

The High Lift Reversible Drum Vac System converts a drum and dolly into a mobile pumping system.

As versatile as the Reversible Drum Vacs are, we also incorporate them into another 2-way pumping system, designed to help you get maximum life and performance from machine tool coolant and cutting oils:  The award-winning Chip Trapper Systems.

The vacuum hose (1) is attached to the barbed connection of the Chip Trapper (2). The directional flow control valve on the top of the drum (3) and knob on the pump (4) are set to the “fill” position. The air supply valve is opened to permit compressed air at 80-100 psig (5.5-6.9 BAR) to flow through the pump which pulls the liquid through the hose, then into the reusable filter bag (5). When all liquid is in the drum, the air supply is turned off. The filtered liquid can then be pumped out by setting the directional flow control valve on top of the drum and the knob on the pump to the “empty” position. Once the air supply valve is opened, the air pushes the liquid back through the hose while all solids remain in the reusable filter bag.

Powered by the Reversible Drum Vac, the Chip Trapper System draws the incoming liquid into the drum through a Filter Bag, which retains (or “traps”) any particulate as the drum fills with liquid.  Then, the freshly filtered liquid can be immediately pumped back out, while the particulate remains in the bag.  Once the bag is full, simply remove the drum lid, unhook the bag, empty it out, and return it to service.  The Chip Trapper System comes with two Filter Bags, in fact, so you can clean one while you use the other.  They are available, from stock, in 30, 55, and 110 gallon sizes.  They are all three available in High Lift configuration as well, with a 20 foot Vacuum Hose.

If you’d like to find out more about safe, reliable and effective liquid handling with EXAIR’s compressed air operated Industrial Housekeeping Productsgive me a call.
