Abstract: The machine is an index spraying machine. The machine has five different stations. The first station is the load/unload station. At this station, work pieces are unloaded after they have been sprayed and new work pieces to be sprayed are loaded on. New pieces then move into the pre-heat station tunnel.

Then they move to the fifth work station where they are cooled and finally they move back into the load/unload station. The spraying area in this machine is sealed to meet NEMA 7 standards. The air capture system cascades the air, thus lowering the air volume that passes through the thermal oxidizer.
