Abstract

In a cooling, reheating or drying tunnel for a series of workpieces passing through the tunnel with a gas passing through it, a series of independently adjustable deflectors are arranged on one, or two facing, walls of the tunnel to give improved variable convection at various points along the tunnel so that various thermal graphs for suitable treatments may be obtd.
