Apart from applications in the furniture and building industry and related sectors, CTP systems are used for air purification in the production of lumber products such as plywood panels, fibre boards (particle boards, MDF, OSB) and compressed wooden parts.
Waste gases are being emitted during the drying process of 'shavings', their subsequent compression, and the wood impregnation and lamination procedures. The characteristic air volumes to be purified are huge (up to 300.000 Nm³/h) with low concentrations of pollutants.
CTP uses regenerative thermal oxidation successfully to remove odor and the distracting impact of 'blue haze' in the factory's surroundings.
CTP's pioneering regenerative thermal oxidiser (RTO) system is a worldwide 'first' for the production process of particle boards. A high cleaning efficiency through the patented RTO ceramic heat exchangers system is another milestone.
Did you know?
In 1994 CTP supplied the world’s first purification system with CTP's heat-exchanger technology for the particleboard industry, being a technological trendsetter as for many other applications. This was the largest RTO in terms of flow-rate at that time.
