The drying process should always be carried out in accordance with the guidelines of the technological process in which compressed air is used. In general, all production processes require a minimum of refrigerated drying, so the installation of a refrigerated dryer and filters is the basis of the drying process. An adsorption dryer should be installed when it is necessary and precisely defined by the compressed air guidelines - Adsorption dryers are several times more expensive and use compressed air for regeneration.
