EXAIR’s Adjustable Spot Cooler: A Versatile Tool for Your Cooling Needs!

 

If you’re looking at replacing messy coolant mist systems, look no further than the Adjustable Spot Cooler. EXAIR’s Adjustable Spot Cooler incorporates Vortex Tube technology to produce temperatures ranging from -30°F – +70°F. A Vortex Tube works by imparting a rapid spinning motion to the supplied compressed air. This airflow makes its way to the end of the tube where it is forced to abruptly change directions. It is during this change of direction that energy is given off in the form of heat. The hot air then exits the tube from the hot end, while cold air exits the other end of the tube. As the valve is opened to allow more air to exhaust from the hot end, the temperature at the cold end will decrease. At a sound level of just 73 dBA when operated at 100 psig and stock generator installed, this compact cooler will keep your operation cool, clean and dry without causing unnecessarily high noise levels.

When looking at a Vortex Tube based solution, the variety of options can sometimes be daunting. This is where the versatility of the Adjustable Spot Cooler shines. Through a simple turn of the control knob, you can easily adjust the temperature and cold fraction of the unit. Additionally, the kits come with (2) extra generators (15-H and 30-H) that can be swapped out for the stock generator for more/less cooling power and air consumption. The 15-H generator will deliver up to 1,000 Btu/hr of cooling capacity and the 30-H will provide up to 2,000 Btu/hr of cooling capacity. We have (2) different kits available, the Model 3825 Single Point and the Model 3925 Dual Point Kit. The 3825 is recommended for use in applications where you’re cooling a small surface such as solder joints, hot melts, or drilled plastics. The 3925 system is better served when heat is generated over a larger surface area such as saw blade cooling. The kits use flexible Loc-Line hose to allow you to precisely position the cold airflow onto your target. The Adjustable Spot Cooler provides easy mounting with a swivel magnetic base, allowing you to mount the cooler directly at the most critical point that heat is being generated.

Multiple Products Provide a Solution to Improve a Laminated Sign Making Process

A manufacturer that produces laminated signs contacted EXAIR for a blow off application. Being that we are experts in this area, I thought this would be a simple solution. The conversation started out about the signs that they manufacture. They are laminated sheets that have a thin aluminum film with a coating on the front and back sides. Their process was to cut stacks of these signs that he called books to specific dimensions. Here is how the conversation went in a shortened version:

Problem –

  1. I need to blow off chips from the saw process.
  2. It has to be strong enough to remove the chips that are melted into the face of the laminate.
  3. When the blade gets dull, the chips become hotter. The operator has to blow on the blade as it is cutting to reduce the amount of chips that melt into the laminated face.
  4. After the machine finishes and the books are removed, the table lifts up and disposes of the excess chips.

Solution –

  1.  Model 1122 2” Flat Super Air Nozzle to blow a wide area off the top of the signs after sawing.

2.  Model 5330 High Power Cold Gun with dual point hose to place on the saw blade. This will extend the life of the blade and help keep the chips cool. Eliminating the melting into the face.

3.  Model: 110248 Super Air Knife Kit to blow the chips from the table after it is lifted.

As you can see, with a simple initial question, it became complicated rather quickly. Instead of looking at one area of the application, I was able to improve their entire process. In any manufacturing plant, scrap and downtime are the two biggest culprits in reducing profits. The scrap occurred when the faces were scratched and damaged. The downtime happened during the cleanup between book change-overs and when the saw blades were being replaced. Overall, their process improved in efficiency and speed.

Whenever you need to look at the overall process for improvement, EXAIR may have multiple solutions to offer. You can speak to an Application Engineer to see how EXAIR can increase your efficiency and reduce your scrap. You can either call 800-903-9247 or send an email to techhelp@exair.com.

Adjustable Spot Cooler Cools Saw Blade

I was recently contacted by a customer looking for a way to cool their band saw blade in a wood cutting operation. They process several different types of wood and when dealing with the more dense products they are seeing the blades heat up, causing them to stop production, change out the blades and scrap the production piece and start the process over. They cannot use a liquid type misting systems as this would contaminate the wood, resulting in more rejects, so they called EXAIR looking for assistance.

I recommended the customer use our Model # 3925 Adjustable Spot Cooler System with Dual Point Hose Kit in the application. The Adjustable Spot Cooler incorporates a Vortex Tube to provide a temperature drop from your supply temperature. By turning the knob on the unit, the temperature control valve allows the user to adjust the temperature range between -30°F up to +70°F, to fit the demand of the application. The flexible tubing is able to hold it’s position, ensuring that the cold airstream is directed towards the critical area(s). The system also features a magnetic base that allows for easy mounting.

With this particular customer, the inherent flexibility of an Adjustable Spot Cooler is a benefit to provide different cooling values depending on the type of wood they are cutting. Using the dual point hose kit they would be able to direct the cold air on each side of the blade to extend the blade’s longevity while decreasing the amount of rejects. Using the filter separator (included with the system), would relieve any concern of fluid contamination by removing any water condensate or particulate in the compressed air supply.

If you are looking to extend the tool life in your operation, give us a call.
