Innovative Alliance: revincus and Rain-O-Tec join forces for the future 


We are excited to announce a groundbreaking partnership with the Austrian wastewater pioneer Rain-O-Tec. As a young, motivated, and innovative startup, we see this collaboration as a unique opportunity to deepen our expertise in environmental technology and expand our product range.

References: Rain-O-Tec has been operating wastewater heat exchangers in swimming pools and industries with high flow rates for over 10 years. These experiences and proven references are also represented by revincus through this cooperation.

Products: Our product range is growing to include a wastewater heat exchanger for high flow rates. Our goal is to supply the German market through this technology exchange and implement our digitized process monitoring in this proven technology.

We look forward to working with Rain-O-Tec and setting new standards together.

144 residential units in Stadtroda will benefit from energy from hot water in the future

Great progress in our project in Stadtroda! A milestone was recently reached in the extensive energy-efficient refurbishment of the WBS 70 residential blocks: Our partner, Heizungsbau Kössel, successfully installed the revincus sewage heat exchangers and sewage diverters. By utilizing our innovative technology for wastewater heat recovery, 144 residential units now benefit from energy from hot water. This measure is part of extensive energy-efficient refurbishment and marks an important step towards sustainable urban development.

More details on this exciting project coming soon!

3D printer from 3DGence next to part of the revincus team

3D printing technology for industry and research


We welcome a new tool in our production - a state-of-the-art industrial 3D printer from the brand 3DGence. With the support of the Thüringer Aufbaubank and the Thuringian Digital Bonus, we were able to make this important investment. This innovative device will enable us to accelerate prototype construction and simultaneously optimize production. With its ability to print larger parts, the 3DGence printer offers almost unlimited flexibility in the design and manufacturing of components for our revincus system. This will help us quickly respond to feedback and continuously improve and develop our products.

Innovation voucher for research - Get started 2gether


We are proud winners of an innovation voucher from the Get started 2gether competition! The support will enable us to conduct more in-depth research into the detection of blackwater and graywater events based on vibration and noise. The visit of Thuringia's Minister of Economics Wolfgang Tiefensee, who personally inspected our wastewater heat recovery technology, gave us an additional boost. On to the next innovation!

ABW-SSW under installation near Dresden

Combination of air source heat pump and revincus technology in new building project


Near Dresden, an exciting new construction project is setting new standards in sustainable heat supply. Our innovative stratified storage wastewater heat exchanger was recently successfully installed there. Thanks to its special technology, this heat exchanger enables the efficient transfer of heat in different layers and temperature zones. Particularly noteworthy about this project is the combination of our wastewater heat recovery system with an air source heat pump. Both heat sources flow together in a hygienic storage tank, providing an efficient and environmentally friendly heat supply. We are pleased to be part of this innovative solution and are excited to see the results of this synergy!

The first round of financing


On 04.12.2020, the first financing round was successfully concluded. The increase in shareholders by Stiftung Thüringen Beteiligungskapital, represented by Beteiligungsmanagement Thüringen, mittelständige Beteiligungsgesellschaft Thüringen mbH and Sparkasse Jena-Saale-Holzland proved to be particularly positive. This success made it possible to obtain an investment in the low seven-figure range, which has since enabled the finalisation of the revincus system and the establishment of the company. A press release was published by the Beteiligungsmanagement Thüringen: To the press release
