November’s Promo Features Cool Products

That’s right, with the start of November this year we also start our Cold Gun promotion. This promotion runs from the start of November until December 31, 2022. The best part is that Cold Guns have a long history of providing spot cooling solutions for industry. Cold Guns have been cooling product and processes for over 35 years! Take advantage of the current promotion today!

The EXAIR Cold Gun promo is a great way to receive an additional tool to extend the use of the Cold Gun. With the purchase of a promotional Cold Gun System w/ Single Point Hose Kit or promotional High Power Cold Gun System w/ Single Point Hose Kit you will receive a Dual Point Hose Kit for free. This is a $48.00 USD value. The Cold Gun will drop your compressed air temperature by 54°F when operating at 100 psig inlet pressure. Choose the standard point tip or the 1″ fan tip to blow the cold air. The total length of the flexible discharge hose is around 11″. If more coverage is needed, the promotional Dual Point Hose Kit gives around 5-6″ of straight hose before splitting into two smaller lines that offer both point or fan tip nozzles as well. This dual point can be used to reach both sides of larger diameter cutters and components that need a blast of cool air.

The Cold Gun is easily setup in any machine that has a ferrous metal surface thanks to its integrated magnetic base that will hold the unit in place even when the machine is moving or vibrating. If you do not have ferrous metal available for the magnetic base, using rigid piping or even something like u-bolts to hold the unit into place is a common practice of customers who need the cooling and know the Cold Gun will perform.

Lastly, if you aren’t certain whether the Cold Gun is the solution, we have an entire team of Application Engineers here to discuss the application, and it is also backed by our 30-day guarantee so our US and Canadian based customers can order one, test it in their facility for 30 days. If they are not pleased with the performance for any reason, the item can be returned to EXAIR. If you want to discuss your application, contact us today!

Engineered, Intelligent Compressed Air® Products: Save Air AND Get a Rebate!

This rebate example results in FREE air nozzles – read on to learn more!

Here at EXAIR we are continuously trying to share the basic facts that engineered air nozzles save compressed air. We then connect that with the amount of money that it saves, this is generally backed with formulas, this isn’t a new concept, we blog, tweet and even have easily accessed calculators for it. The final part that we like to share is that, on top of saving throughout the life of the nozzle, there are also many energy providers and municipalities that extend a rebate program as well! That means this lowers the ROI on implementing engineered nozzles into your system.

For instance, if your facility is located in Holland, Michigan, the Holland Board of Public Works wants to offer a rather simple rebate that requires the engineered nozzle and application be installed and submitted by December 31, 2022. The program is offering up to $100 per engineered nozzle installed on an open pipe or tube. (The incentive cannot exceed 100% of customer cost.) Not sure if you have open pipes in your facility? I’m sure you will hear them if you walk near the production lines where air is used. Or, better yet, get in touch with your production maintenance team and have them go throughout the facility and perform an open tube/pipe tagging event. Then report back and contact an Application Engineer here at EXAIR. We will all be able to help you with selecting the appropriately sized engineered nozzle to convert that open pipe/tube blowoff to an efficient and safe blowoff.

The Holland program is focused on open pipe/tube blowoffs while there are countless other programs out there which focus on replacing any blowoff with an engineered nozzle that also fits certain flow criteria for select pipe sizes. These programs can be searched by using the site Dsireusa.org This is a site that is maintained by NC State University and NC Clean Energy Technology. You can easily navigate to your state and scan the list for a rebate program which will then even take you to the application and stipulations for the selected incentive.

No matter where you are located in the world, you don’t have to use a rebate to save money by installing engineered nozzles. The savings and ROI all starts as soon as they are installed. The rebates available in various parts of the US are just ways to expedite the ROI. If you want to discuss any engineered nozzle application, contact an Application Engineer today.

Take It All In – Just Filter It

The Nose – Only the Nose Knows

Take a nice deep breath as you read this. In through the nose. If you are like me right now, due to Fall allergies you’ll have a little bit of a restriction, hold it for just a second and then breathe out through the mouth. The body is an amazing thing, when we breathe in through our nose the body has some natural filtration built in that is also known as nose hair. While not the most attractive thing to most, it is important. The hairs in the nose help to filter out allergens and catch foreign debris.

Other items you interact with daily have similar air intake filtration. A car often has both an intake air filter and even an in-cabin air filter, these both protect various parts. The engine air filter is vital to prevent dust, debris and even excessive water from entering into the precision machined and assembled motor. The HVAC system in every business or home generally has an intake air filter in order to protect the coils and heater box.

There’s another system in most manufacturing facilities that should always have a filter on it, and that is the compressed air system. Properly maintaining and filtering the incoming ambient air feed before it is compressed starts the process of on the right foot to optimize performance and insure efficiency is maintained from the start of the entire process. These filters are like many others and can be part of a preventative maintenance program. The air compressor manufacturer will have a recommendation on frequency for the various types.

If these filters are left unchanged then the compressor begins to have restricted flow on the intake which then results in less air being pulled in or maybe the filter is removed and then the debris all gets pulled in and sent through to become foreign debris inside the compressor. Both of these will cause the compressor to wear or overheat and work harder to compress the air and send it into the storage tank. This results in premature maintenance needed on the compressors and or point of use devices.

Thus, always filter your incoming air. Whether for your air compressor, car engine, or house, start with a fresh intake and then keep it optimized from there. The payback will be longer lasting equipment that operates at a higher efficiency. And remember, breathe in through your nose.

If you would like to discuss your filtration setups, feel free to reach out to an Application Engineer.

Fundamental Modes of Heat Transfer

Generally I like to write about cool stuff. Whether it is a new product like our TurboBlast Safety Air Gun, an application that really helped cool down a process for a customer, or even something cool I have done like a GORUCK event or training. Well, today is not one of those days, today we are going to talk about the opposite of cool … HEAT and more importantly the methods it is transferred.

1 – Energy Transfer – Heat

The process of how heat is generated all starts with a conversion of energy. Whether it is friction, or converting energy to light, or even converting energy to a different voltage through something like a transformer. No matter how it is generated, heat will begin to transfer. On the molecular level, atoms are storing the energy which will cause electrons to enter into an excited state and rapidly switch between shells. When the electron returns back to a lower shell (closer to the nucleus) energy is released; the energy released is then absorbed by atoms at a lower energy state and will continue until the thermal energy is equal between the two objects. Heat has four fundamental modes of transferring energy from surface to surface and they are as follows:

Conduction
Conduction can also be referred to as diffusion and is the transfer of energy between two objects that have made physical contact. When the two objects come into contact with each other thermal energy will flow from the object with the higher temp to the object with the lower temp. A good example of this is placing ice in a glass of water. The temperature is much lower than the room temperature therefore the thermal energy will flow from the water to the ice.

Radiation
Radiation is the transfer of thermal energy through empty space and does require a material between the two objects. Going back to the how thermal energy is released from atoms; when the electron returns to a lower energy shell the energy is released in the form of light ranging from infrared light to UV light. Energy in the form of light can then be absorbed by an object in the form of heat. Everyone experiences radiation transfer every day when you walk outside; the light from the sun’s radiation is what keeps this planet habitable.

Convection
Convection is the transfer of thermal energy between an object and a fluid in motion. The faster the fluid moves the faster heat is transferred. This relies on the specific heat property of a molecule in order to determine the rate at which heat will be transferred. The low the specific heat of a molecule the faster and more volume of the fluid will need to move in order to get full affect of convection. Convection is used in modern ovens in order to get a more even heat through out the food while cooking.

Advection
Advection is the physical transport of a fluid from point A to point B, which includes all internal thermal energy stored inside. Advection can be seen as one of the simpler ways of heat transfer.

No matter how the heat is transferred to an object, if it needs to be cooled there is a good chance that one of our Application Engineers has approached a similar issue and can help. To discuss, contact us and we will walk through the best method to eliminate the heat you need to.
