“RF/T” dryers for fabrics

The fabric is fed by a spreading and centring unit to the drying chamber, where it passes through a set of patented (Double-Polarity) Radio Frequency electrodes. The fabric conveying system is equipped with motorised rollers that prevent any tension of the fabric. The air circulating in the drying chamber comes from the RF generator cooling system (for heat recovery) and its temperature is suitably controlled.

The water vapour released by the fabric is evacuated by an air extraction fan. A sophisticated moisture detection and control system at the exit adjusts automatically both the conveying speed and the RF power delivery in order to maintain the residual moisture content of the fabric as set by the operator, with an accuracy of +/-0.5%.
