Viesel Apparatebau GmbH
Bad UrachNew on Amplifa
Family-owned company for stainless steel heat exchangers from Bad Urach
Viesel Apparatebau GmbH is a family-owned company based in Bad Urach near Stuttgart, specialising in the production of heat exchangers and replacement tube bundles made of stainless steel. The company exclusively manufactures custom-made products instead of series products: compact U-tube bundle heat exchangers, robust straight-tube heat exchangers as well as steam generators and steam condensers. This is preceded by individually determined material, thermal and profitability calculations, a detailed data sheet and 3D visualisation of the component. The offering also includes maintenance service, repair, spare parts, replacement tube bundles including installation service, as well as complete components for combined heat and power units (CHP). Manufacturing is carried out in accordance with EN ISO 3834-3 using tungsten inert gas welding, with approval for pressure vessels under the Pressure Equipment Directive (PED, Modules A, A2, G) for wall thicknesses up to 15 mm, lengths up to 10 m, a maximum diameter of 1200 mm and unit weights up to 10 t. Customers include, among others, companies from the brewery and beverage industry, the food industry, plant engineering, swimming pool, solar and temperature control technology, exhaust gas and condensing technology, as well as data centres.

History
At the beginning of the company's history was the production of rendering machines, rotors and stators.
More than 50 years ago, production of heat exchangers made of stainless steel began, initially smaller units for swimming pool construction.
Establishment among plant engineers of the brewery and food industry thanks to extensive experience and state-of-the-art computer technology.
Expansion to include the production of complete components for various manufacturers of combined heat and power units as well as further development of heat exchanger technology in the exhaust gas and condensing sector.
