SHEETFED DRYING/CURING SYSTEMS -- Running Hot and Cold

Circle 382 on Reader Service Card

Accel Graphic Systems manufactures the Tempest hot air dryer, which uses PTC thermistors instead of IR elements to accelerate the drying process. Thermistors are self-regulating semiconductors that use a phenomenon called autostabilization to maintain a constant temperature without the need of a thermostat. Heat is generated when an electrical current is applied to the unit.
