A cleanroom is an environment that has a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. A cleanroom has a controlled level of contamination and is used in manufacturing, biotechnology, the life sciences and other fields that are very sensitive to environmental contamination. Cleanrooms maintain particulate-free air through the use of HEPA filters (High-efficiency particulate absorption), employing laminar air flow principles. The clean room tumble dryers are a specific range of equipment designed for applications in which maximum hygiene and a dust-free environment are important such as pharmaceutical plants, virology laboratories, high-tech industries and food-processing industries. We are offering a complete range of tumble dryers in a Clean Room versión, from 11 to 80kg, (models DTP-11 to DTP-80) and in three heating types: electric, gas and steam. By means of a HEPA 13 filter and a pre-filter, the air coming into the dryer is purified before getting into the heating battery and the drum.
