We made a cooling conveyor for a company in Pittston, PA. Red hot axles are placed in the end and are cooled as they travel through. The speed of the conveyor is very slow and is timed to cool at just the right rate to ensure the axle properties are correct. This machine was extensively modified after installation to obtain greater cooling capacity by the end user. Each of the side panels now have a cooling fan bolted to it. This has been in use daily since 2002 and has had almost no problems.
