Inside the In-Line RHT, an oven designed for continuous parts cleaning, racks and hooks travel through a refractory-lined heated chamber, where air temperature of 1,000 to 1,200oF (537 to 648oC) ignite the paint, turning it to ash. The hooks and racks then are conveyed to a washer, where water cools them, removing most of the ash. The process is completed by two basic components: a heat source and an air distribution system. The heat source is an air heater with a gas-fired burner. The burner operates under pressure and is connected to a blower that provides filtered air to the air heater. The heated air then is transferred to the process area through an air distribution system, a network of ducting and jet pipes.
