Energy-Saving PET Dryer

摘要

New PCT~3 Series desiccant dryer from Universal Dynamics, Inc., Woodbridge, Va., is designed to minimize energy use at every stage of the drying process. It is aimed at high-temperature drying, such as PET, and for low-temperature PLA biopolymers. Air flow is optimized with variable-speed blowers and temperature sensing. A water-saver valve minimizes water use to cool air on the return side. And regeneration exhaust air is recycled to a heat exchanger to preheat air for the regeneration heater.
