WELTEC Biopower

WELTEC Biopower GmbH plans, produces and distributes biogas plants in stainless steel worldwide. With more than 80 employees, the company has realised more than 300 plants in Europe, the USA, Cyprus and Japan.

WELTEC has been the worldwide market leader in the field of biogas plants in stainless steel for years and, with the expertise of its employees, specialises in complete plants from single sources.

The strength of this medium-sized company is individual solutions – from compact plants to large computer-controlled plants in the megawatt range, from waste-utilisation plants to biogas parks with gas treatment technology.


ProMos Bio is a project that has been developed in successful cooperation with a strong partner, WELTEC Biopower GmbH from Vechta. With ProMos Bio  Proventa AG broke new ground and developed a licence product for both the German and international markets. The user was always in focus in the process, and thus the management software for plant operators was developed and optimised with the support of plant operators. ProMos Bio stands for transparency, efficiency and predictability and leads plants from today into the future with complete plant documentation. With a web application (SaaS) and two native apps (Android and iOS), ProMos Bio can be used in every plant individually and flexibly, helping users to manage and optimise their biogas plants.


Development, test and operation are realised by Proventa AG – ProMos Bio was not awarded the certificate "Software made in Germany" for nothing.


The individual software ProMos Bio was realised in cooperation with WELTEC Biopower from Vechta and launched after only ten months of development time as a market-ready product at the EnergyDecentral in the course of EuroTier 2014.

A web application (SaaS) was developed, along with two native apps (iOS and Android) to ensure reliable data recording offline as well.

The Scrum framework was successfully used in the project management, and an iterative process ensured that ProMos Bio actually meets the needs of the user.

In June 2014, after only four months of development, the software was in use at eight plants from different manufacturers and of different types and tested for functionality and usability.

ProMos Bio was developed in accordance with the highest data-protection standards in the world, and implementation was overseen by a certified data-protection specialist.

Development, test, maintenance and operation are realised and ensured by Proventa AG.
