Use Less Energy to Dry PET

摘要

Novatec Inc., Baltimore (novatec.com), is introducing two patented dryer control technologies intended to cut energy costs for processors of PET. Approximately 60% to 65% of the energy required to dry PET is used to raise the temperature of the resin and boil off the moisture, explains Mark Haynie, Novatec's dryer sales product manager. About 30% to 35% of the power is used in regeneration of the desiccant, and only 5% to 10% is for operation of the blowers and control power.
