EXAIR Cabinet Cooler in Bahrain Still Operating Years Later, In Harsh Conditions

img-20170110-wa0010

This small NEMA 12 type Cabinet Cooler has been in operation for years. Now, two additional units are needed for new applications.

A few weeks ago I was contacted by a mechanical contractor in Bahrain about a needed Cabinet Cooler.  Their customer had an existing unit in place and needed two more for similar applications.  As with any Cabinet Cooler need, we needed to start with an accurate understanding of the heat load involved, to make sure we recommend the proper model number.

So, we used the Cabinet Cooler Sizing Guide to gather the required information and calculate the heat load of the application.  After using this information to calculate a heat load of 426 BTU/hr. (~125W), we confirmed that the existing model 4308-240 will be the correct fit for the additional cabinets as well.

Even in this dirty environment the Cabinet Cooler continues to function.

The existing Cabinet Cooler has been in operation for several years without any required maintenance or upkeep.  Clean compressed air, achieved with a simple 5 micron water/dirt filter separator,  is supplied to the unit and nothing but clean cold air is fed into the cabinet.  Relative humidity is regulated by the Cabinet Cooler to 45% resulting in stable temperatures and humidity for the electronics inside the enclosure.

The dirt and debris are prevented from entering the enclosure due to the design of the Cabinet Cooler. Only clean, cold air enters the cabinet. Hot air is vented away.

This application is an excellent example of the durability of EXAIR products.  With proper compressed air supply our products will operate uninterrupted and at proper performance for years.  If you’re in need of a durable solution for an electrical enclosure, contact an EXAIR Application Engineer.

You Might be Freezing, but Your Electronics Can Still Overheat

For those of us in the Northern Hemisphere it can be easy to be overrun by static elimination problems during these winter months.  But, colder outside temperatures don’t always mean cooler temperatures for the electronics used in production processes.

This cabinet was facing unaddressed overheating issues before exploring a Cabinet Cooler solution

I received an email from one of our distributors this week describing two applications with failing electronics (shown above and below).  The root cause of failure for both applications was excessive heat inside the enclosures which house electronic devices, even though the ambient air temperatures weren’t abnormally high.  So, we used the Cabinet Cooler Sizing Guide to determine the heat load of each application and make recommendations for proper Cabinet Cooler model numbers.

This cabinet was also overheating, causing problems in the processes controlled by the components inside the cabinet.

What we found was that the heat load in both cases was rather low, but in each case it was enough to cause the electronics to overheat.  When the temperature of the electronic devices exceeds their specified temperature range, they cease to operate, causing downtime of every device tied to the processes they control.  By installing a Cabinet Cooler onto each enclosure, the overheating problem will be quickly and easily solved.  And, because of the relatively low heat load in this application, a small NEMA 12 type Cabinet Cooler was the perfect solution.

If you have an overheating electrical enclosure, whether during the Winter, Spring, Summer, or Fall, contact an EXAIR Application Engineer.  We’ll be happy to help.

How To Solve A Problem with Compressed Air

In my (almost) six years as an EXAIR Application Engineer, I’ve learned a great many things about the capabilities of our products.  The way we do business sure does make it easy:

  • We readily share application information, as a team.  If you ask me a question, you’re asking all of us.  It does neither of us any good if I tell you something MIGHT work if one of my team knows it WON’T – or if someone knows what else DOES work.  If we can offer a solution, we will.
  • We’ll test your product, free of charge.  This is a popular way of finding out which Line Vac is best for conveying a particular product, for example.
  • If you’re considering a quiet, safe, and efficient EXAIR product as an upgrade, we’ll test your current product in our award winning Efficiency Lab, so you can compare accurate performance data and analyze the expected benefits…which can be dramatic.  Try us on that.

  • We’ll let YOU test our product, risk-free.  All catalog products come with a 30 Day Unconditional Guarantee.  We invite you to put it through its paces for up to a month.  If it’s not working out, we’ll arrange return for full credit.
  • We’ll do the math.  But first, a disclaimer: strictly comparing the force or flow of an engineered product to an open-end blow off won’t always tell the tale.  Our Intelligent Compressed Air Products are creating a laminar flow which won’t generate as high of a force/thrust as open-end blowing (which is turbulent by nature,) but is MUCH more conducive to efficiency and noise reduction, as well as similar (if not improved) performance.  But back to the math: if you know the metrics you need to meet for spot cooling (like a Vortex Tube, Adjustable Spot Cooler, Cold Gun, etc.) or for liquid spraying (the liquid flow rate and/or pattern size & shape from an Atomizing Spray Nozzle, for instance,) or the heat load that a Cabinet Cooler System can handle, we’ll do the calculations and specify the appropriate product.

Regardless of the application, if it can be solved with compressed air, it’s very likely that we have a great solution.  Call me to find out how we can help.

A 20 Year Old Cabinet Cooler Reveals our Small World

Recently, I had dinner with some family that I hadn’t seen in a quite a while.  As part of catching up and reminiscing about old times, the discussion went to professions and ‘what are you doing now?’  I told my uncle that I was doing Application Engineering for EXAIR Corporation, and he asked about what we do. I responded that we manufacture an extensive array of Intelligent Compressed Air Products, and then gave a few specifics, like Air Knives, Line Vacs, and Cabinet Cooler Systems. Since my uncle had worked in the chemical process and research industry for many years, he was at least familiar with the products I had mentioned.  He then shared stories about the facility he works at, and because I had worked there many years ago in college (driving a forklift), he knew I would appreciate hearing about all the changes in the last quarter decade.  Eventually, the evening came to and end and we went our separate ways.

Very soon after I received a text message with the below photo attached. Sure enough, my uncle had come across an EXAIR Cabinet Cooler System installed in his facility.  Based on the photo, I identified it as a NEMA 12 model, with a cooling capacity of 275 or 550 BTU/hr. When I did an order history search, I confirmed it was a model 4208 (550 BTU/hr) and found it had shipped in August of 1995, and that my uncle’s name was listed as the order contact, since he placed the order.

Small World!

Model 4208, NEMA 12 Cabinet Cooler System, Installed in 1995 – Still Working Today

Speaking of small worlds, the model 4208 and it’s little brother model 4204, are perfect for small cabinet enclosures that have a minor amounts of internal heat generation, such as a power supply, or moderate outside heat transfer.  Capable of producing 550 BTU/hr and 275 BTU/hr of cooling while using just 8 and 4 SCFM of 100 PSIG compressed air, the EXAIR Cabinet Cooler Systems offer a great way to keep cabinets cool and worry free, as evidenced by over 20 years of operation.  Just provide clean air (a simple 5 micron water/dirt filter is recommended) and it will operate worry free for a long time.

EXAIR manufactures Cabinet Cooler Systems from 275 to 5600 BTU/hr, for NEMA 12, NEMA 4 and NEMA 4X enclosures. They are available in Continuous Operation, (2) Types of Thermostat Control, special designs for High Temperature environments, and a Non- Hazardous Purge. Materials of construction include aluminum, stainless steel, and type 316 stainless steel.

To discuss your application and how an EXAIR Cabinet Cooler System would help out, feel free to contact EXAIR and one of our Application Engineers can help you determine the best solution.

EXAIR Cabinet Cooler Systems – Reliable Protection For Vital Equipment

It’s November, and I’ve had to scrape ice from my windshield three times this week. I’m not complaining – I surrendered the right to complain about the cold when I moved from Florida to Ohio, on purpose, some 25 years ago…this month, in fact. I’m just making an observation. And noting that it’s 73 degrees & sunny in Cocoa Beach right now.

But it is a noteworthy time to be getting urgent calls about cooling applications, like the one I got just the other day.  A manufacturing facility had just suffered the loss of a VERY expensive installation of Variable Frequency Drives (VFD’s) because of a failure of the refrigerant-based cooling system that had come, pre-installed, on the panel.  This machinery, being critical to their process, needed to be brought back on line, RIGHT NOW, and they were the better part of a week away from getting a service technician to look at their current coolers.  They had much better luck with the VFD’s; thanks to a good relationship with a prompt repair service provider, they were going to be operational the next day.  But obviously, they wouldn’t be in operation for very long without proper cooling.

Enter the EXAIR Cabinet Cooler System.  Now, we LOVE to calculate the heat load from the operating conditions of an existing system, but since this one wasn’t running, we were left with estimating the heat load, based on the power requirements of the VFD’s – which did indeed line up with the capacity of the failed A/C system, so we offered a Model 4870 NEMA 4 Cabinet Cooler System – 4,800 Btu/hr – with Thermostat Control.  As a stock catalog product, it was available for same-day shipment, allowing them to resume operation just as quickly as the VFD’s could be restored. The EXAIR Cabinet Cooler product line is available in NEMA 12, 4, and 4X – and also a NEMA 4X in 316SS option for those harsher, more corrosive environments.

EXAIR Cabinet Cooler Systems offer reliable protection from heat, year-round

EXAIR Cabinet Cooler Systems offer reliable protection from heat, year-round.

No matter how cold it gets outside, there are lots of “hot spots” in many workplaces that just don’t care about the regional climate.  If you…or, more to the point, your critical electronics…are in one of those places, isn’t reliable protection a reasonable consideration?  Give me a call; let’s talk.

Adding Thermostat Controls To An Existing Cabinet Cooler Application is Easy & Intelligent

dsc00493

The image above shows a NEMA 4 Cabinet Cooler after years of use in a food production facility.  The head electrician at the facility which uses this unit, contacted me regarding the possibility of installing thermostat controls on a pre-installed Cabinet Cooler systems.  Apparently there are multiple EXAIR Cabinet Coolers in use around this facility, and as part of an improvement to compressed air efficiency, this facility wanted to explore automated regulation of the temperature in these enclosures (through thermostats). THis customer inquiry was about how to go about implementing such an upgrade.

It was refreshing for the end user to find that we have mechanical thermostat controls, solenoids, and even digital thermostatic solutions available from stock, making the upgrading process easy and pain-free.  After some conversations over the phone and emailing part numbers along with our Cabinet Cooler Installation and Maintenance Guide, which outlines how to install the thermostat for our Cabinet Cooler systems, this customer had everything required to do exactly what they needed in their facility.  (In this case, our model 9016 Solenoid Valve and Thermostat Kit met the voltage and compressed air flow requirements needed for the application.)

Providing efficient, controlled, and reliable solutions for industrial applications is all we do at EXAIR.  If you have an application in need of a complete solution, or just an upgrade, contact an EXAIR Application Engineer.  We’re happy to help.
