Resulting from regeneration by means of compressor heat, these dryers are under the influence of compressor operation. Utilisation in explosion proof zones presents no problem and can be arranged on the basis of simple modifications. Pressure change and release to atmosphere are not necessary, thus avoiding disturbing noise levels. The closed loop system pollutes the surrounding air neither with cold, wet nor with hot regeneration air. High inlet temperatures accompanied by low operating pressure exert a strong influence on the design of the dryers.
