Put salt in your water solution. this creates a brime solution that will extract the heat a bit quicker. We have cooling fans mounted on both the exit end of the wave and atop my exiting conveyor mechanism. What type of composite material are you using. We don't have any heat problems coming out of the wave with our CDM materials.

We need to use them in order to protect the contact gold fingers. We are currently using conductive cooling system by submerging them in water but anyhow at the moment of using them they are still hot and wet. Is there any possibility of using convective methods and some kind of rolling conveyors or something?
