ANA Prozesstechnik GmbH is your partner for planning, engineering and production of apparatus and plants for the chemical industry, oleochemistry as well as environmental and power plant technology. Bank on our know-how and decades of experience. Paul Wiegand assumed leadership of the company in 1951. Rudolf Jahn and Karl Stief became general partners. The company secured good markets worldwide through patented technical solutions. From 1961 the company had to be continued under state control.
In 1908 Wilhelm Wiegand, plant manager of his father's leather factory, developed the first evaporator for the economic concentration of tanning liquor. Since the initial plant was already superior to the customary concentration plants, the Wiegand evaporator was quickly accepted by other industry sectors.
Wiegand products were first exported in 1928. During this time, the jet apparatus department of 'Blancke' company from Merseburg was acquired and the delivery program expanded by steam jet plants.
In 1929 'Wilhelm Wiegand Maschinenfabrik KG' was founded.
In1944 a heavy air raid destroyed the production facilities; rebuilding was started immediately after the end of the war. A proprietary circulation pump of the SIEVA type that was able to extract boiling liquids from the vacuum was the cause of a sudden expansion of the application area of the Wiegand products.
Since 1990the 'Apparatebau Merseburg GmbH' became an independent medium-sized company through reprivatisation.
In 1994 the company became 'ANA Anlagen- und Apparatebau GmbH Merseburg'.
In May of 2000 the machines and other equipment as well as the technical documentation was purchased by new shareholders and ANA-Verfahrenstechnik GmbH was established. Production was continued at the old site.
In 2007 the distillation technology was introduced and oleochemical plant engineering was started.
In2010 the company moved to the new production site at Herrfurthstraße 9 in Merseburg.
