DENCOHAPPEL

The origin of today's DencoHappel goes back to 1909, when the German air filter construction company with limited liability (DELBAG) was founded in Breslau. On the other hand, Otto Happel founded the "Gesellschaft für Entstaubungs-Anlagen GmbH" (GEA) in Bochum in 1920, and in Great Britain, DENCO was founded in 1944, which was taken over by GEA in 2006. Starting with the production of textile filters to filter the cooling air of electric machines, Otto Happel. By 1922, he revolutionized the c... irculatory water cooling system of large electric machines by using the elliptical finned tube, which was launched on the heating market after 1945. The next major step took place in 1954 with the founding ofHAPPEL KG, in which the continuously expanded manufacture of convectors was consolidated. In 1970 – fifty years after its founding – the current DencoHappel could refer to 8,000 air-cooled installations in process engineering, and simultaneously the 500,000th heating unit left the factory. The breathtakingly fast growth of the company demanded new business structures. In order to finance the influx of capital, GEA AG was gradually transformed and went public in 1989. More
