The E.S.C.H. GmbH was set up in 1992 to apply existing expertise in pneumatic conveying technology in iron and steel industry, to develop new processes in order to transfer them to other industrial branches. Since this time the E.S.C.H. GmbH has been commissioning different dosing, injection, absorbing and transportation plants on blast furnaces, converters and electrometallurgy workshops, aluminum melting aggregates, and other industrial plants. The main technological targets of the designed facilities are the improvement of the environmental impact by absorbing toxic contaminants from exhaust gas as well as the reduction of the costs of production by saving of raw materials and substitution of oil and gas with alternative solid fuels.
