Thorwesten is a brand name, especially in the building materials industry, automatically connected to design, fabrication and erection of silo storage facilities. Explosion pressure shock resistant silos with explosion vents for storage of combustible materials with the potential to form dust explosion hazards, became a complementary specialist activity. Thorwesten Vent GmbH was formed in 1996 as result of the increased business volume in this special field. A dedicated team of specialists in explosion protection and silo storage, serves the highly special demands of the market, sharing the premises and manufacturing facilities with Silobau Thorwesten GmbH, the silo specialists. By tradition, both companies have strong ties to the cement industry. Beckum is located in an area with a dense spread of cement plant, which, in the late seventies made the conversion from gas and oil, to lignite fired kilns. Lignite and coal found favour as important fuel for the cement industry in other parts of the world, after the oil crisis in the seventies. As a result, Thorwesten Vent GmbH's activities cover mainly, but not solely, engineering, fabrication and realisation of explosion protection. We design and supply explosion doors for pressure shock resistant silos, for solid fuels like coal, lignite and petcoke and for other combustible bulk materials. The revolutionary, patented air-cushioned explosion door is key technology in this field. Today, Thorwesten Vent GmbH is involved in explosion protection of process plant, combining explosion venting and decoupling of interconnected vessels like separators and dust collectors in fuel grinding plant. Due to the world wide marketing of pressure shock resistant and explosion vented silos, which often require a high degree of local manufacturing, we offer to all our engineering expertise in explosion protection.
