Cabinet Cooler Selection

Published on by Al WooffittLeave a comment

EXAIR‘s Cabinet Coolers are a low-cost and reliable way to cool and purge your electrical panels. They incorporate our Vortex Tubes to produce cold air from compressed air. With no moving parts, our Cabinet Coolers can run maintenance free for many years.

When selecting which Cabinet Cooler is right for your application, there are a few things for you to consider:

First, is your cabinet in a hazardous location? We have HazLoc Cabinet Cooler models that are rated for UL Classified areas, including Class I Div 1, Groups A, B, C, and D; Class II Div 1, Groups E, F, and G; and Class III; as well as ATEX rated units that are approved for use in Zones 2 and 22. All of our hazardous location Cabinet Cooler Systems need to be used in conjunction with a purged and pressurized control system.

From right to left: Small NEMA 12, Large NEMA 12, Large NEMA 4X

After this you will need to determine what NEMA integrity your enclosure requires.
We have NEMA 12(IP54) models, which are dust and oil tight. These are ideal for most industrial environments where no liquids or corrosives are present.
Our NEMA 4(IP66) options can be used inside and outside, and are splash resistant as well as dust tight and oil tight. The low-pressure relief valve will ensure the integrity of the NEMA 4 enclosure is maintained.
Finally, our NEMA 4X(IP66) option offers all the same protection as the NEMA 4X, but is constructed of stainless steel for food service and corrosive environments.

Next, you need to decide if you need continuous operation or thermostat control. The thermostat control systems are the most efficient way to operate a Cabinet Cooler. They save on compressed air by only activating the cooler only when the internal temperatures approach critical levels. The standard thermostat control systems include an adjustable thermostat factory set at 95°F. We also have our Electronic Temperature Control (ETC), which allows for precise temperature control that can be adjusted with the touch of a button.

ETC Electronic Temperature Control can be used in a wide variety of applications.

Finally, you will need to calculate the heat load to determine the cooling capacity. We have a calculator on our website that can help with this. However, if you speak to any of our Application Engineers, we can perform these calculations for you. If you would like to discuss your Cabinet Cooler application, feel free to give us a call!

Case Study: Heavy Duty Dry Vac for the Win!

Published on by Al WooffittLeave a comment

A couple of months ago, I was speaking with a customer about improving a process in their facility. They were using electric shop vacs to vacuum up fiber and dust from around their operating equipment. The shop vacs that they were using were not very powerful, meaning it was taking operators a long time to get the job done. In addition, the vacs were prone to wearing out, leading to a need for frequent replacements – they had already gone through 13 in the last 12 months alone!

I was happy to recommend an EXAIR Heavy Duty Dry Vac. With no moving parts to wear out, our steel drum vacuum system was a one-time replacement. Even with the higher initial cost, taking into account we are eliminating the need to purchase replacements every month, the EXAIR drum vac will quickly pay for itself. The better vacuum performance also meant the operators were saving about 3.5 hours per week, leading to even more savings. The ROI on this change was less than 5 months. That’s a win!

In addition to the immediate savings, we also discussed EXAIR’s Case Study program. A typical case study involves collection of “before/after” data, quantifying the benefits of using EXAIR products. This can include, but is not necessarily limited to:

  • Compressed air consumption
  • Noise level
  • Safety (OSHA compliance)
  • Performance improvements
  • Product durability/longevity

My customer was able to quantify the benefits in both product durability and performance improvements. As an added benefit, upon successful completion of a case study, I was able to provide the option of a credit on the replacement products, or a discount on a subsequent order. Now it’s a win-win!

If you would like to discuss how EXAIR products can save you money, or if your application would be suitable for a case study, then give me a call!

Utility Rebates – How EXAIR Products Can Save You Money!

Published on by Al WooffittLeave a comment

We love to talk about how our intelligent compressed air products can save you money. This has been the subject of many blogs, emails and phone calls; primarily focusing on how our products will reduce your overall air consumption. This leads to lower energy costs, which over time will save you thousands of dollars. Another way you can save money is through rebate programs.

Many electrical companies offer rebates for efficient products and programs that help reduce energy consumption. The NC Clean Energy Technology Center has created a website that consolidates this information for you on their website: www.dsireusa.org.  “DSIRE is the most comprehensive source of information on incentives and policies that support renewable and energy efficiency in the United States”. Since EXAIR’s products fall into this category, rebates can be applied to the use of our products. If there is a rebate available, you will find it on this site.

It’s easy to find what rebates are available for you by selecting your state from the map on DSIRE, and then filtering down to Technology > Energy Efficiency > Industrial Equipment > Compressed air. As an example, in Michigan there is currently a rebate from Energy Smart for using Engineered Nozzles.

Once you’ve found your rebate, give us a call! We can help you determine which of our products will allow you to take advantage of it, whether it’s one of our engineered nozzles like the above example, or any of our other intelligent compressed air products.
