Rabmer GreenTech GmbH, founded in 1963 and led since 2002 by Ulrike Rabmer-Koller, is an Upper Austrian family business specializing in wastewater energy systems. The company develops and implements solutions for extracting renewable energy from wastewater through innovative self-cleaning heat exchangers and heat pumps. Wastewater is recognized by the EU (since 2018) as a renewable energy source, maintaining temperatures between 12-20°C year-round in sewers, making it suitable for heating and cooling applications. The technology can recover up to two-thirds of heat from wastewater and potentially cover up to 14% of heating demand. Rabmer accompanies projects from initial potential analysis through feasibility studies, design, and implementation, serving industry, commerce, and municipalities.
