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.
