A new wheel-type desiccant dryer is said to save both energy and floorspace. The IntelliPET dryer from Novatec, Inc., Baltimore, reportedly uses 40% to 50% less energy than dual-bed desiccant dryers, and also reportedly occupies 40% to 45% less floorspace than competing wheel-type dryers for PET. Novatec says the new unit also costs less than other wheel-type dryers for PET. One key to the unit’s efficiency is its two-zone drying hopper; another is the reuse of heated air returning to the dryer from the hopper. Inside the dryer, the return air is filtered and then is split into two process streams. One stream is cooled before passing through the desiccant wheel and then is reheated before entering the lower zone of the hopper. The other air stream is still hot enough that it requires only minimal reheating before entering the upper hopper zone. The dryer includes an electric or gas-fired heater, a cyclone, and optional self-cleaning, pulse-type dust collector. (410) 789-4811 • www.novatec.com
