This conveyorized system was designed to heat and anneal PVC parts at a very controlled rate and then to cool the parts back down to room temperature prior to offloading. The infrared oven length measured 37 feet long. Ten zones of temperature control in the machine direction were incorporated to control the heating rate over a 2.5 minute residence time. The cooling section measured 75 feet in length. Chilled water coils were integrated and zoned to effectively provide cooling air to the product.
