Abstract
A paint drying system for drying a painted body (4), such as a painted motor vehicle, includes a spraybooth (1) having an enclosure (2) through which air flows from an air inlet (6) to an air outlet (16, 18). The spraybooth (1) may also have columns of air jets (34) mounted in respective corners of the enclosure (2) to direct air obliquely at surfaces of the vehicle body (4). The system includes ionization members (33) for electrically charging this air supply. In a preferred embodiment the air is negatively charged by ionization members comprising one or elongate rods (33) mounted parallel with the columns of air jets (34). The spraybooth (2) may also have a control system (210) for controlling the paint drying system (4). The control system (210) has user-operable controls (234) to pre-select a predetermined parameter/combination of parameters and thus control the characteristics of a respective drying stage or cycle which parameters, e.g. temperature, vary with time.
