About BOWA
BOWA GmbH Apparate- und Behälterbau has been manufacturing components and systems from steel, stainless steel and non-ferrous metals in Aschau am Inn for over 75 years. The range of services includes apparatus construction (autoclaves, columns, pressure vessels, distillation and extraction apparatus), vessel construction (heat exchangers, buffer storage tanks, expansion vessels, steam boilers, agitated vessels, storage tanks, mixers, dryers, silos), piping construction, structural steelwork up to EXC2, special machinery construction as well as complete systems such as vacuum filling systems. The core process is fusion welding (111, 135, 141, 142) with certified production dimensions up to 12 m in length, Ø 4000 mm and 10 t unit weight; this is complemented by sheet metal processing, surface finishing, painting, contract pickling and chimney technology. The offering is rounded out by industrial services such as assembly, maintenance, repair, servicing, damage analysis as well as conversion and dismantling of systems. Customers come from the food, chemical and pharmaceutical industries, environmental technology, the automotive industry, construction, jig and fixture building and agriculture. The company belongs to the Linster Group.
