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.

***Order an EXAIR Cabinet Cooler System before July 31, 2017, and get a FREE AC Sensor!***

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.

Camera Lens Cooling with EXAIR Vortex Tubes in a High Temperature Environment

Connection side of camera lens housing. Dimensions shown are in cm.

A customer in Russia contacted our distributor in Moscow about an application to monitor the flow of melted glass.  In their application, the end user had installed (4) camera “eyes” with thermal insulation to instantaneously measure the melted glass flow.  But, the high ambient temperatures would cause the temperature of the camera lens to slowly increase during operation, eventually resulting in an overheating condition.  This overheating condition rendered the cameras inoperable until they were cooled below a temperature of approximately 40°C (104°F).

What this end user (and application) needed was a suitable solution to cool the lens of the camera to a temperature below 40°C (104°F).  A typical refrigerant based air conditioner wouldn’t work for this application due to space and temperature constraints, as the cameras are located close to the furnace with ambient temperatures of 50°C (122°F) or higher.

What did provide a viable solution, however, were High Temperature EXAIR Vortex Tubes.  Suitable for temperatures up to 93°C (200°F), and capable of providing cooling capacities as high as 10,200 BTU/hr., these units fit the bill for this application.

Full view of the camera lens housing. The camera lens is the portion protruding from the far left of the housing.

After determining the volume of compressed air available for each camera, and after discussing the solution options and preferences with the customer, they chose (4) model BPHT3298 Vortex Tubes, using (1) Vortex Tube for each camera.  The cold air from the Vortex Tube will feed directly onto the camera lens, keeping it cool even in the hot ambient conditions.  This removes lost productivity due to machine downtime, which in turn increases output and reliability from the application process.

High Temperature Vortex Tubes provided a solution for this customer when other options were unable to deliver.  If you have a similar application or would like to discuss how an EXAIR Vortex Tube could solve an overheating problem in your application, contact an EXAIR Application Engineer.  We’ll be happy to help.

Trouble Identifying an EXAIR part? Don’t worry, we’ve got you covered!

3240VT

EXAIR Model 3240H Vortex Tube with Hot Muffler Installed

 

Not a day goes by that we don’t receive a call from a customer that is having trouble identifying an EXAIR part. Due to the robust nature of our Vortex Tubes, they can be installed in applications for several years without any maintenance. When the time comes to expand that line, the labels may have worn off, the unit may be covered in grime or oil, or the personnel that originally ordered the product may no longer be with the company. In any case, one of the Application Engineers here at EXAIR will certainly be able to help!

I recently received an e-mail from a gentlemen in Indonesia who was suffering from that very problem. They had a Model 3240 Vortex Tube installed in a camera cooling application near a boiler. The engineer who designed the project was no longer with the company and they could not determine a Model number or when they had purchased it. They saw the EXAIR sticker, along with our contact information, and reached out for help. Vortex Tube’s come in different sizes, based on the available compressed air supply as well as the level of refrigeration needed. They’re available in (3) different sizes as well as Vortex Tubes for max refrigeration (R style generators) and Vortex Tubes for a maximum cold temperature (C style generators). In order to identify the Model number, you must look on the shoulder of the Vortex Tube generator. On it, there will be a stamp that indicates the generator style that is installed. In this case, the customer stated that there was a “40-R”, indicating to me that he had our Model 3240 Vortex Tube.

Our team of highly trained Application Engineers is here ready to assist you with any needs you may have regarding EXAIR products. With a little bit of investigative work, a quick discussion about the dimensions or a photo; we’re able to identify any of our products. If you’re considering expanding a current line into other parts of your facility, or perhaps adding a new location and need help identifying your EXAIR products; give an Application Engineer a call and we’ll be sure you get the right products on order!

Music And The Mini Cooler

Recently, EXAIR Corporation offered CPR (cardiopulmonary resuscitation) training to employees. I already carry certification, so I held down the fort while some of the other Application Engineers received this training. As a middle aged man, I have to admit that my interest in my co-workers’ abilities to respond to a matter of this nature is not entirely unselfish.

One of the key parts of CPR training is the rate of the chest compressions. While most people couldn’t accurately replicate 100 beats per minute on demand, almost everyone is familiar enough with some popular songs with a rhythm close to that.  The song they always bring up in CPR training is “Stayin’ Alive” by the Bee Gees. Depending on how you feel about disco, another option is “Another One Bites The Dust” by Queen. Pro tip: it might be considered bad form to sing that one out loud while performing CPR.

Speaking of music, while I was holding down said fort during this morning’s training session, I had the pleasure of assisting a caller in the music business: a piano restoration & tuning professional. A frequent job for them consists of resetting tuning pins, which requires drilling numerous small holes (a grand piano can have as many as 250) into a hardwood board. They’re pressed in, so it’s critical that they fit the newly-drilled hole precisely. If the drill bit gets too hot, it can expand in diameter, making the hole ever-so-slightly bigger than it should be. The heat can also cause the surface of the hole ID to glaze. Both of those things can cause problems with the pin fitting securely in the hole.

The EXAIR Model 3808 Mini Cooler System was an ideal solution – it’ll keep the drill bit cool & clean with a constant stream of cold air. It’s compact and quiet, and only uses 8 SCFM @100psig…well within the capacity of many smaller air compressors.

If you’d like to “get in tune” with a spot cooling solution, I can help…call me. Oh, and in case you wanted to know which song with about 100 beats per minute I’d use for CPR:

EXAIR Cabinet Cooler System Meets High Demands Of Sea Duty

I joined the Navy, right after high school, to get out of Ohio, see the world, and never come back. “My recruiter said” (if you are considering military service, those can be famous last words, just so you know) that I would be a good candidate for Nuclear Power School, so I took the test. As a math & science nerd scholar, I qualified for admission easily.  About halfway through Nuke School, I volunteered for submarines.  My decision was based in no small part on the sea stories of our instructors, the strong reputation of better food, and my deep appreciation for the movie “Operation Petticoat.”

Upon graduation, I was assigned to a new construction Trident submarine.  I did not see the world…I saw the Electric Boat shipyard in Groton, Connecticut, and Naval Submarine Base King’s Bay, Georgia.  Hilarity occasionally ensued, but never in the context of that movie I so adored.  I moved back to Ohio (on purpose) soon after my enlistment was up.  The food WAS good…I can unreservedly vouch for that.

In the new construction environment of the shipyard, I became quite familiar, and developed a deep respect for, the high level of attention paid to the materials and workmanship that a seagoing vessel demanded…not to mention, one with a nuclear reactor on board.  Reliability and durability are obviously key factors.

I had the pleasure recently of assisting an electrical contractor who was looking for a cooling solution for a new Variable Frequency Drive enclosure installation on a cement barge.  The ship’s engineer (a Navy veteran himself) had told the contractor that his priorities were reliability, durability, and dust exclusion.  He couldn’t have made a better case for an EXAIR Cabinet Cooling System.

Based on the specified heat load of the VFD, the size of the enclosure, and its location, a Model 4380 Thermostat Controlled NEMA 12 Cabinet Cooler System, rated at 5,600 Btu/hr, was specified.  This equipment is internal to the ship; had it been exposed to the elements, a NEMA 4X system would have been presented.

Up to 2,800 Btu/hr cooling capacity with a single Cabinet Cooler System (left) or as much as 5,600 Btu/hr with a Dual system (right.)

EXAIR Cabinet Cooler Systems have no moving parts to wear, no electric motor to burn out, and no heat transfer surfaces (like a refrigerant-based unit’s fins & tubes) to foul.  Once it’s properly installed on a sealed enclosure, the internal components never see anything but cold, clean air.

If you have a need to protect an electrical enclosure in aggressive environment, give me a call.  With a wide range of Cabinet Cooler Systems to meet a variety of needs, we’ve got the one you’re looking for, in stock and ready to ship.
