Enjoy this Summer by Avoiding Heat Related Electrical Problems with Cabinet Cooler® Systems

For many of us, summer contains some of the most enjoyable months coming up in North America. Summer typically brings more time spent outside, basking in the sunshine, lemonade, iced tea, grilling, gardening, fishing, hiking etc.

These enjoyable hot summer months coming upon us can also bring some elevated temperatures within electric control panels – but we have a simple and effective solution to avoid any heat related shutdowns and interference with electrical systems.  EXAIR can eliminate these with our Cabinet Cooler Systems, you just get on with the grilling and basking in the sun.

With freon based coolers, higher ambient conditions make them less effective; and opening the electrical panel to have a fan blow inside creates a dangerous electrical hazard.  For every 10 oC rise above the operational temperature, the life of an electrical component is cut in half.  To reduce loss in production and premature equipment failures, it is important to keep your electrical mechanisms cool.  The EXAIR Cabinet Coolers are designed to do just that.

How the EXAIR Cabinet Cooler System Works

How does the Cabinet Cooler work? 

Cabinet Coolers are powered by an EXAIR Vortex Tube which only uses compressed air to generate cold air.  They do not have any moving parts, Freon to leak, or refrigerant compressors to fail.  These simple, but effective, cooling devices can be used in the toughest of environments.  With the Vortex Tube as the “engine”, the reliability of the EXAIR Cabinet Cooler is unmatched and makes it an easy choice for cooling electrical panels.

What NEMA ratings does EXAIR offer? 

To match the same integrity as your electrical panels, EXAIR offers three different types of NEMA ratings that are UL listed and CE compliant.  NEMA 12 is dust and oil tight, and can be related to the IEC standard, IP54.  NEMA 4 is dust and oil tight as well as splash resistant for indoor and outdoor use.  The NEMA 4X is the same as the NEMA 4 except it is made of stainless steel for corrosive areas and aggressive wash-down environments.  Both the NEMA 4 and 4x corresponds to an IP66 rating.  EXAIR Cabinet Coolers are easily installed and can match your electrical panel to keep the electrical components safe inside.

What size Cabinet Cooler do I need? 

EXAIR makes it easy to get the proper cooling with the Cabinet Cooler Sizing Guide.  This guide goes over the important information to determine the external and internal heat loads.  It also indicates the proper NEMA type and electrical requirements for easy installation. The cooling power ranges from 275 BTU/hr to 5,600 BTU/hr, and with the filled-out form, we can make sure that the correct model is used.

Thermostat- Controlled System

What types of systems are offered? 

EXAIR offers a continuous operating system and a thermostat-controlled system.  The continuous operating system includes the selected Cabinet Cooler, a filter, and a cold air distribution kit.  The system will continuously cool until it is manually or automatically turned off.

The thermostat-controlled system is the most efficient way to operate a Cabinet Cooler.  This system comes with the selected Cabinet Cooler, filter, cold air distribution kit, a thermostat and an electrical solenoid valve.  The system is designed to operate only when cooling is needed.  The thermostat controls a solenoid valve, and it is preset at 95°F (35°C).  The thermostat can be easily adjusted to match other desired temperatures.  The solenoid valves come in three different voltages, 120Vac, 240Vac, and 24Vdc (which ever voltage is easily accessible).  With the thermostat-controlled system, you do not have worry about the system operating during off-peak conditions or cooler seasons.

What other options does EXAIR offer with the Cabinet Cooler Systems? 

For better temperature control, EXAIR can replace the standard thermostat and solenoid valve with the ETC, or Electronic Temperature Control.  It is a digital temperature controller with a LED screen for precision monitoring and adjusting.  The controller has easy-to-use buttons to raise or lower the desired internal cabinet temperature.  Once set, the ETC will hold the temperature to +/- 1 oF (+/- 0.5 oC).  The LED displays the internal temperature for continuous monitoring.  The ETC comes complete with the controller and a solenoid valve in two different voltages, 120Vac and 240Vac.  The ETC is a great option for real-time accurate measurements for your panel cooling.

Another option that EXAIR offers is the Side Mount Kit.  They are used to mount the Cabinet Coolers on the side of the electrical panel.  They are manufactured to match the NEMA rating of the Cabinet Cooler.  If you have limited space, don’t worry.  The Side Mount Kits gives you more areas to mount the Cabinet Cooler to your electrical panel.

What about harsh environments? 

  • With elevated ambient temperatures like near ovens, the high temperature version would be your option. The HT Cabinet Coolers work in temperatures from 125 oF to 200 oF (52 oC to 93 oC respectively).  With refrigerant coolers, the elevated temperatures make it very difficult to cool effectively.  But with the EXAIR HT Cabinet Coolers, the high temperature will not affect the ability to blow cool air.
  • If the environment is extremely dirty with lint, fibers, debris, etc., EXAIR offers an NHP, or Non-Hazardous Purge, version. The solenoid valve is designed to allow 1 SCFM of compressed air into the panel to keep a slight positive pressure. With the NHP Cabinet Coolers, the ingress of any fine particles into your electrical panels are eliminated.
  • For food and beverage, pharmaceutical, and corrosive type of applications, EXAIR can offer NEMA 4X Cabinet Coolers made from 316SS material. With the high corrosion resistance, the 316SS Cabinet Coolers will continue to operate without degrading in tough environments.
  • In Class I, Class II, and Class III hazardous areas, EXAIR has the HazLoc Cabinet Coolers. They are UL classified and can work with X-type and Z-type purge systems for the thermostat-controlled system.  The solenoid valves are also designed to be located in these areas with the same three different voltages.  The Hazloc Cabinet Coolers can be sold as a continuous operating system as well.

Happy Independence Day From EXAIR!

Please Note: EXAIR will be closed July 4th in observation of the United States Independence Day

Summer is my favorite time of year. Warm weather, hanging out by the pool, and enjoying the outdoors (weather permitting of course). It’s also the time of year when my favorite holiday occurs, Independence Day. EXAIR will be closed on July 4th in celebration of Independence Day. On this day 243 years ago the Declaration of Independence was adopted, marking the official legal separation of the Thirteen Colonies from Great Britain.

Although today we celebrate on July 4th, Congress actually voted to declare independence two days earlier on July 2nd. If it were up to John Adams, that would be the date we commemorate to this day. He wrote in a letter to his wife that this would be the most memorable day in the history of America, to be celebrated by pomp and parade, games, sports, guns, bells, bonfires, and illuminations from one end of this continent to the other. In protest of July 4th being designated a federal holiday, he was reported to turn down invitations to appear. Coincidentally, both he and Thomas Jefferson both passed away on July 4, 1829 on the 50th anniversary of the adoption of the Declaration of Independence.

I imagine the celebrations looked quite a bit different back then, but today many of us will spend time with our family and friends enjoying some BBQ. Parades and firework shows are also in abundance as we celebrate together as a country in unison.

“America was not built on fear. America was built on courage, on imagination and an unbeatable determination to do the job at hand.” – Harry S. Truman

The very same can be said of EXAIR, built on the courage, imagination and determination of our late founder Roy Sweeney. Without his willingness to take risks and build his version of the American Dream, we would have never come to be.

So while we celebrate, hot dog in hand, take a moment to reflect on what it means to be an American. Enjoy your right to life, liberty, and the pursuit of happiness. To all of my fellow Americans on behalf of EXAIR, Happy Birthday to US!

Memorial Day 2016

On Monday, Memorial Day will be celebrated across the United States. It’s a third day to a (usually) fair-weathered weekend. It also means that Brian (and I, and I’m sure we’re not the only ones) will be making some S’mores. Lee’s sister can delve into the lighter colors in her closet. And, of course, American flags are in line up & down the streets in my neighborhood.

Many of us who are military veterans receive thanks for our service from time to time. And most of us will acknowledge that it was our honor to serve. But not on Monday – we didn’t earn that. Memorial Day is when we remember those who lost their lives while serving in our nation’s defense.

I got to serve during a time of peace. I’m grateful that I never saw combat, and I’m humbled to share the distinction of “veteran” with those who did. Those who saw combat may very likely know someone they will remember on Monday.  Others will remember a friend or family member…may they know comfort and peace from the thanks of a grateful nation.

Whatever your plans are this weekend, I encourage you to spend the time…even if it’s a just a moment…to consider the price that’s been paid for the freedoms we enjoy.  And have a great Memorial Day – it’s been paid for.

Memorial Day

Taking Yourself Out Of Your Comfort Zone

During the warmer Ohio weather months, April through October, my blog posts may include information about taking my motorcycle to some road course tracks (and now even a cold month or two).  I take my bike to open track days where (mostly) amateur riders can get on a proper race course. There are people on the track for the first time and people who race professionally.   They will generally divide the riders into several groups, Novice, Intermediate or Advanced.  The control riders/coaches at the track will help you to determine what group you should ride in and then help you throughout the day.   Below is a video of a control rider that is also a professional rider at Mid Ohio Sports Car Course.  (Don’t mind the music, it’s not my cup of tea either.)

For the novice group there are classes after each session, as well as skills practiced in every session.  This is to help teach the beginning track rider that the same habits you use on the street are not meant for the track, as well as how to be as safe as possible while being on the track.  This is the most watched and controlled group due to the fact it generally has the most riders and they are all the newest to the track.

For intermediate group there are optional classes and you just run your own pace.  They step up the skill level by not enforcing you to focus on a skill during each session or requiring you to go to a class after each session of the day.  The pace is considerably faster than novice and the only ways to get instruction are to either ask a control rider for it or if they see something to help you with they will generally stop you and coach you on how to do it better.

The final group is advanced, or race class.  This has the same elements as a professional race minus the grid at start-up.   There aren’t really any passing rules and the control riders are mainly all professional racers or former racers who can still make your head spin as they fly past you.  Similar to the intermediate group the only way you will get help is to ask for it.

For the past two years I have been running in the intermediate group and it is a serious meat grinder.  You will have people in there that are fast enough to be in advanced group, but are too scared.  As well as having people who let their ego and pride tell them they don’t need to learn anything from a novice class and should really be in novice learning as much as they can.  I stayed in Novice for over the first year of track riding that I had done.   Some people choose to never leave the novice group because that is exactly where they are comfortable.  They don’t want to worry about the other classes and are perfectly fine with not even being the fastest person in Novice.  This is perfectly acceptable for some, but I had to push myself out of my comfort zone in order to really enjoy the entire experience.  Even though I have been to the track several times now I am always out of my comfort zone in intermediate because there are always new people showing up and you never know when you will running with a group that should be racing, or a group that should be getting coached in novice.

Here at EXAIR we have customers that could fit into each of these groups also.   The customer who doesn’t know what an engineered solution is and doesn’t understand the cost of compressed air.  The intermediate user who has used some of our products in the past but is encountering new issues and knows that we can help lead them in the right direction.  As well as the advanced users who know exactly what they need and sometimes even request a special unit to fit their exact needs.

No matter the case, we can help as well as coach even the most advanced users of our products on how to use compressed air better.  If you are reading this and you don’t know the difference between a Super Air Nozzle and an open pipe, then give us a call.  We will help teach you the differences as well as make sure you understand the need for engineered solutions on your compressed air system.  It may be out of your comfort zone for the first few calls but we will make sure you get to the level you want to be so you get back into your comfort zone.
