Compressed Air Uses In Industry

From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.

Compressed air is used in virtually every industry!

 

Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.

Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

EXAIR has been providing engineered solutions since 1983.

EXAIR Cabinet Coolers, Solve Your Overheating Issues Today!

EXAIR NEMA 4X Cabinet Coolers

Industrial facilities incorporate a variety of processes and procedures to meet customer demands.  The ability to convert incoming resources into the desired output hinges upon proper up-time inside of the facility.  Whether producing raw materials, performing value-adding services, or manufacturing consumer goods, downtime and failed systems inside of an industrial facility mean lost throughput, lost profit, and increased cost.

As temperatures begin to rise across the US, heat related equipment failures become more prevalent.  Industrial facilities need a way to alleviate the problems caused by these increased temperatures and to mitigate the risk of failing electrical devices due to heat.

EXAIR Cabinet Coolers provide this solution using nothing but compressed air.

EXAIR Cabinet Coolers convert a source of compressed air into a very cold stream of air, capable of cooling a sealed enclosure.  They are mounted directly to the enclosure, feeding in air as low as 18°F (-8°C) to bring the internal temperature of the cabinet down to acceptable levels.  While the cold air generated by the Cabinet Cooler is fed into the enclosure, hot air is simultaneously removed, maintaining relative humidity inside the enclosure at 45%.

Rated for use in NEMA 12 (IP54), NEMA 4, and NEMA 4X (IP66) environments, EXAIR Cabinet Coolers are available in aluminum, 303 stainless steel, and 316 stainless steel.  No matter the material of construction, EXAIR Cabinet Coolers can provide 275 – 5,600 BTU/hr. of cooling capacity in industrial applications with ambient temperatures up to 125°F (52°C).  For hotter environments up to 200°F (93°C), High Temperature Cabinet Coolers are available.

In extremely dirty environments, Non-Hazardous Purge systems provide a continuous stream of air (1 CFM) into the enclosure, maintaining a positive pressure and preventing any dust intrusion.

Each system type and material are available to ship from stock*, allowing fast delivery to your facility and quickly solving an overheating condition of your devices.

Never do this! This setup forces dust and contaminants into the control panel, compromising the electrical components inside.

Fans and traditional air conditioners can effectively remove heat, but they provide no separation between the sensitive components inside of an enclosure and the dirty industrial environment outside.  Simply installing a fan or AC unit can allow dust, oil, and other ambient contaminants into the enclosure, leading the failure of the expensive equipment inside.  And, these solutions degrade over a finite lifespan (the Cabinet Cooler does not), they require routine maintenance (the Cabinet Cooler does not), and they need more time to install (Cabinet Cooler installation is fast and simple).  Curious how easy it is to install an EXAIR Cabinet Cooler?  Check out this video and see just how easy it really is.

For those applications without enough spacing to mount a Cabinet Cooler on top of the enclosure, Side Mount Kits are available.  These kits are also available from stock and are just as easy to install:

All EXAIR Cabinet Coolers are available with thermostat controls to regulate internal cabinet temperatures and compressed air consumption.  EXAIR thermostats feature a bimetallic contact strip to open and close the electrical circuit in response to air temperatures.  These thermostats quickly respond to changes in air temperature and are specifically suited for their intended use.  Preset for 95°F (35°C), a suitable temperature for most electronic devices, these thermostats are fully adjustable for specific application needs.

In the event a more sophisticated thermostat control is needed, Electronic Temperature Control units can be implemented.  These standalone units utilize a thermocouple to determine internal cabinet temperatures which display onto a digital readout.  Push-button controls on the digital readout board allow for easy modification of the internal cabinet temperature set-point.  When the desired internal temperature is reached, the Cabinet Cooler will turn off automatically.

Is it really that easy?  Can a Cabinet Cooler provide real cooling for sensitive devices and last for years without any maintenance?  Well, here’s an example:

(Click for larger view) The image on top shows year one of the Cabinet Cooler’s life, and the image on the bottom shows year six.

An automotive radiator manufacturer experienced a problem with an overheated motor drive, causing one of their production lines to come to a stop.  The root cause of the failure was a leaking refrigerant-based air conditioner, which failed and allowed water into the enclosure housing the motor controls.  When the water entered the enclosure, it shorted the motor drive and caused the production line stoppage. The new drive cost over $20,000 and a month of down time to purchase, receive, and install.

Following this failure, the customer searched for a more suitable cooling solution and installed an EXAIR model 4330 NEMA 12 2,000 BTU/hr. Cabinet Cooler System.  With an included thermostat control, this system provided proper cooling for the application without any need for required maintenance or potential to leak water into the enclosure.

Fast forward six years and this same customer reached out to EXAIR for another application.  During the conversation they mentioned the Cabinet Cooler they purchased many years before was still in operation, still providing proper cooling for the enclosure, and that no maintenance had been performed (Cabinet Coolers do not require routine maintenance).  Even in the dirty industrial environment of this manufacturing facility, the EXAIR Cabinet Cooler continued to function flawlessly.

When exploring industrial solutions, required routine maintenance is a common concern.  The cost of replacement components and time required to perform necessary maintenance weigh heavily on decision makers.  Fortunately, EXAIR Cabinet Coolers do not require any maintenance, and with clean, dry compressed air their lifespan can be 20 years or more.  There are no moving parts to wear out or routine maintenance services to be performed.

If you’re in need of a suitable cooling solution for an industrial enclosure, consider an EXAIR Cabinet Cooler.  They’re smaller than traditional AC units, faster to install, and require little-to-no-maintenance.  Feel free to contact an EXAIR Application Engineer with any questions, or fill out our online Cabinet Cooler Sizing Guide to have an Application Engineer contact you.

Cabinet Cooler Systems Save The Day, Every Day

Summertime temperatures get hot. Protect your electronics with an EXAIR Cabinet Cooler System.

As you may have seen in our most recent E-NEWS Special Bulletin, or experienced in real life (depending on where you’re located,) most of the eastern United States is seeing a pretty significant heat wave for early summer…or, as we call it at EXAIR, “Cabinet Cooler Season.”  And this year is kicking it off with a bang, for sure.

On Tuesday, when the E-NEWS email went out, I was on the phone, processing an order for a Model 4340 NEMA 12, 2,800 Btu/hr, Thermostat Controlled Cabinet Cooler System, to ship overnight to a user who wanted to protect the new drive they were replacing because theirs overheated.  They were up and running before noon on Wednesday.

On Wednesday, four local customers placed “will call” orders for Cabinet Cooler Systems.  I had the pleasure of talking with one of them, who was installing one for the very first time.  As he was looking over the Installation & Operation Guide before he left our building, he just wanted to make sure that hooking it up was as simple as it sounded…and it is.  We pulled the parts from the box and went over exactly how each step is performed, and he left feeling confident that he’d have it installed pretty quickly.  Just in case, I also got his email address and sent him a link to our NEMA 4 Cabinet Cooler System Installation Video Blog:

I don’t know what the rest of the summer holds in store, but I know this: if you have concerns about protecting sensitive, critical, and/or expensive electrical & electronic enclosures, EXAIR Cabinet Cooler Systems are the solution you’re looking for.  Easy to install.  Maintenance free operation.  Durable, UL Listed, and CE Compliant.  If you’d like to discuss your application and get one for yourself, call me; let’s talk.

Non Hazardous Purge Cabinet Cooler System Keeps Enclosure Dust Free

A mining company has processing machinery operating in a poorly ventilated, dusty environment (actually, it’s a mine…as you might have guessed.) This machine’s control panel was supplied with filtered vents and fans to cool the electronic components inside. The filters clog regularly, and even though they checked them frequently, it’s not always frequently enough to prevent the drive from overheating.

Based on a referral they got from another one of their facilities, they called to get more information on a Cabinet Cooler System. For total dust exclusion, our Non-Hazardous Purge systems are ideal…they’re thermostatically controlled, so compressed air consumption is responsible and efficient, but they also provide a small, continuous flow, even when the thermostat set point temperature is attained, and the solenoid valve is shut. This keeps a low positive purge volume of clean, dry air in the enclosure.

EXAIR Non Hazardous Purge Cabinet Cooler Systems provide reliable and efficient cooling in the most aggressive environments.

The caller already had the data from our Cabinet Cooler Sizing Guide, so specification was quick & easy. A Model NHP4340 NEMA 12 Non-Hazardous Purge Cabinet Cooler System – 2,800 Btu/hr – w/Thermostat Control was ordered and installed the next day. We keep them in stock for situations just like this.

If you have heat issues with electrical & electronic equipment enclosures, give me a call.

Beat the Heat with EXAIR Cabinet Coolers!

As we begin to approach the heat of summer in the northern hemisphere, we begin to break out the flip-flops, swimsuits, and warm weather attire. If you’re not a fan of the warmer temperatures, this may not be your favorite time of year. For me, I can’t wait to spend some time outdoors and enjoy all of the activities that summer has to offer. Whether you like the heat or not one thing is certain, the electrical enclosures within your facility most certainly do not.

CC_Actionshot

EXAIR’s Cabinet Cooler Systems were designed specifically to rectify these issues within your facility. Utilizing Vortex Tube technology, the Cabinet Cooler produces cold air from an ordinary supply of compressed air. This cold air keeps the enclosure free of debris and moisture and is easily installed in minutes through a standard electrical knockout. Here is a short video that shows just how simple it really is. The Cabinet Cooler Systems are available with Nema 12 (IP54) ratings and are also available in Aluminum, 303 Stainless Steel, and 316 Stainless Steel construction for Nema 4 (IP66) rated enclosures. For systems that are not able to be mounted on top of the cabinet, we also have Side Mount Kits available in Aluminum, 303 Stainless, and 316 Stainless.

These systems are available with cooling capacities of anywhere from 275-5,600 Btu/hr. To make things much easier for you, we offer a Cabinet Cooler Sizing Guide that will allow us to recommend the most suitable model for your cabinet. With a few quick measurements, we’ll be able to determine the exact heat load that we’ll need to dissipate and offer you a quick and easy solution. If you’re experiencing heat related issues somewhere within your facility or remember the troubles that they caused you last year, contact an Application Engineer today and we’ll see to it that this summer your cabinets remain cool!

Keeping Sensitive Equipment Cool with an EXAIR Cabinet Cooler

The image above shows a sophisticated microscope used in a highly controlled environment to monitor living cells.  The end user of this microscope recently contacted the Application Engineering department at EXAIR in search of a method to cool the internal temperature of the microscope chamber from 22°C (72°F) to 14°C (57°F).

The small space of this application made the use of a typical refrigerant based air conditioner an impossibility.  But, near to this microscope is a source of very dry, clean, oil free compressed air – perfect for operating a Cabinet Cooler.

The internal heat load of this application was known by the end user, but the effects of external heat load on the application were still unclear.  In order to determine the full heat load of the application a Cabinet Cooler Sizing Guide must be used to perform heat load calculations.  This document, once complete, allows EXAIR to determine both internal and external heat loads, which in turn allows us to determine the required Cabinet Cooler model number.

This application was served by the model 4325 Cabinet Cooler, which allowed for a cooling solution in tight spacing where a traditional air conditioning unit wouldn’t work.  The small and compact design of the Cabinet Cooler was the perfect fit for this customer and application need.  If you have an application in need of a cooling solution, contact an EXAIR Application Engineer.  We’ll be happy to help.
