Dorset also has an excellent product for cleaning the air used in the drying process. During the last 15 years, Dorset has built up an excellent reputation in this area. Dorset Air Washers have been certified in various countries, amongst others by the German Agricultural Society (DLG). This experience was necessary for being able to develop special air washers for after the digestate drying process. Dorset air washers reduce ammonia, dust and odours. Both a production hall placement and a container dryer can be combined with Dorset air washers. With container dryers, the air washing unit can possibly even be installed in the container itself.
