Abstract
A dryer (10) for printed textiles and substrates is disclosed having a plurality of infrared-based sensors (60) therein for monitoring the temperature of the products as opposed to the ambient environment. Each sensor (60) is positioned within a projecting sensor housing (55,58). The sensor housing (55,58) has an annular chamber (70) to protect and cool the sensor (60). A chilling/dehumidifying system (100) is also disclosed that incorporates a dehumidifier (110) and, humidity monitors (160).
