		VOC is a collective name for volatile hydrocarbons, which are characterised through high vapour pressures and low boiling points. The abbreviation VOC stands for “Volatile Organic Compounds“. There are two sources for VOC: either they have a natural origin from all forms of life (humans, animals, plants, micro- organisms, etc.) or they have an anthropogenic origin coming from solvents, cooling agents, road traffic, etc. VOC endanger the human health and the environment, since they can cause fatigue, headache and sensitization. They can also be irritating to eyes, skin and mucous membranes or even carcinogenic. The threat for the environment is the formation of greenhouse gases and ground-level ozone in combination with NO_x. Therefore it is necessary that standards are established. The VOC-regulation by the European Union says that the threshold value must not exceed 50 mgC/m³ or 0,5 kg/h. The treatment of VOC in the photovoltaic-, semiconductor and related industries, is an important topic since solvents, deposition gases and pastes are released in the various processes. The photovoltaic- industry should lead the way as a “green industry”.


Features and Benefits Very long MTBM (typically 1 year) Very low hydrocarbon emission (< 20 mg C/Nm³) High DRE (> 99.5 %) for all VOC Low primary-energy consumption (12 – 35 kW) due to energy recovery (hot air for drying furnace or hot water)
