About KVK Koerner
KVK Koerner (Koerner Chemieanlagenbau Ges.m.b.H.) is an Austrian plant manufacturer based in Wies, Styria, specializing in turnkey hot-dip galvanizing plants, pickling plants for stainless steel, black steel pipes and non-ferrous metals, and exhaust air purification systems. The company manufactures pickling tanks made of glass-fiber reinforced synthetic resin (GRP) and acid-resistant plastics in its own production, develops encapsulated pre-treatment systems, exhaust air scrubbers with heat recovery and special coatings, and acts as general contractor from planning through production to commissioning. The core materials are chemical-resistant plastics, steel, stainless steel and non-ferrous metals; process media treated include hydrochloric acid, hydrofluoric acid, sulfuric acid and NOx. Customers include galvanizers, pipe picklers and the chemical industry; reference plants have been built, among others, in Europe, Japan, Australia, the Middle East and Canada. The company, restructured as a GmbH in 1985/86 with origins as a boat yard from 1950, employs around 80 staff. Digital tools such as KVK PicklingOptimizer and PicklingTimer as well as refurbishment, maintenance and training complement the portfolio.
