Our cooling flash rooms and tunnels produce rapid chilling and high product throughput to help prevent flaws such as bubbles, cracks, and cloudy areas in your finished surfaces. EPA cooling tunnels provide precise temperature reduction for continuous process systems, increasing line speeds and reducing overall manufacturing time. Similar in design to convection ovens, cooling tunnels have no heating capability. Instead they use blowers to distribute mechanically cooled air across part surfaces, while drawing away unwanted, heated air. Passing air across parts in this way results in more even cooling along with significantly faster cooling times.
