A few weeks ago I worked with a nail and staple gun manufacturer on a glue cooling process involving their collated nail strips. To keep the nails together, they place a small amount of hot glue across the body of the nails and then have an open air line blowing compressed air on the glue to secure a good bond between the pieces. The current process used to work great, but they recently made a change to the type of glue they were using and now they are starting to see more rejects as the heat from the glue isn’t able to be removed quick enough with ambient air. The customer is familiar with EXAIR as they currently use some of our other products in various applications throughout their plant but in this particular case, they were unsure of the best product to fit their needs so they reached out for assistance.
For this particular application, I suggested the customer use our Mini Cooler. The Mini Cooler is specifically designed for small area or small part cooling applications. The Mini Cooler uses less compressed air than our Cold Gun but still produces the same 50°F temperature drop from the incoming supply air temperature. So say your plant air is 70°F, you would see 20°F air being exhausted from the unit. The device features a flexible hose, allowing the user to focus the cold air to the desired location, in this case right at the glue which would provide the quicker, more reliable solution the customer was needing. Installation is a breeze as well, thanks to the included magnetic base, you don’t need to make any expensive modifications or add any type of mounting brackets to the existing setup.
EXAIR offers a wide variety of spot cooling products that provide a low cost, maintenance free solution for large or small scale cooling processes. With help selecting the best product to fit your specific need or to discuss your particular application, please contact an application engineer for assistance.
