Jaske & Wolf VerfahrenstechnikGmbH
About
Jaske & Wolf Verfahrenstechnik GmbH, based in Lingen, Germany, specializes in thermal energy recovery from wastewater, geothermal sources, and industrial process streams. Founded by Wolfgang Jaske and Dr. Peter Wolf, the company's flagship product is the DUPUR® continuously self-cleaning heat exchanger, which uses an integrated intelligent pigging system to automatically clean heat-transfer surfaces during operation — solving the chronic fouling problem that plagues conventional heat exchangers in dirty media. The DUPUR system has been deployed at the Moskaubad swimming facility in Osnabrück (recovering heat from pool backwash water), at the Bad Neuenahr-Ahrweiler thermal spring (achieving approximately 600 kW heating capacity and 4–5 GWh annual output, saving 800–1,000 tonnes of CO₂ per year versus natural gas), and in industrial laundries where warm wastewater preheats fresh water from 10°C to 25–28°C. Beyond heat exchangers, Jaske & Wolf offers the TaxoGrid modular low-temperature district heating and cooling network concept, turnkey heating centers as general contractor (KPP public-private partnership model), sludge drying systems, and treatment solutions for biogas digestate and flexographic printing wastewater. All solutions comply with EU Taxonomy sustainability criteria.
