About Karl Hopf GmbH
Founded in 1906, Karl Hopf GmbH is a medium-sized family company in its fourth generation headquartered in Bayreuth. The company, with around 70 employees, implements solutions in the fields of building technology (sanitary, heating, air conditioning), ventilation technology with heat recovery and residential ventilation, environmental technology, plant and apparatus engineering as well as locksmith and metal construction work. In plant and apparatus engineering, thermodynamics is applied in particular in the drying of ceramic products and in wastewater treatment for industrial production processes. The range of services covers requirements analysis, planning, project engineering, manufacture, installation through to commissioning as well as maintenance, customer service and emergency service, including turnkey systems. Customers include industry, trade, municipalities, public-sector clients and private customers; projects are implemented in northern Bavaria, nationwide, across Europe and in part worldwide. For the development of a phase separation system for splitting emulsions, the company received the Bavarian State Prize in 1990.
