Sheetfed Drying/Curing — A Cure-All for UV Inks

Positive Alternative

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