Rely on our long-term experience and reliable products

About us

We are your competent partner for more than 30 years - from planning until commissioning and support. Our service-team will take care of the support of your odour control plant. Efficient project management ensures the cost-effective realization of high-quality plant engineering.

Our Vision

Environment protection is a global concern ... that is why we are acting globally!

Combining long-term experience with state of the art technique

Since the company was founded in 1986 we have steadily expanded our product range. We want to continue on one hand to keep proven products and on the other hand to foster constantly new product developmets to integrate improvements. That way we can offer you the best odour control design anytime.

Customization for your individual problem

We do not prepare standard offers, but individual and tailor-made customizations according to the latest state of the technology. To ensure that, our engineers voluntarily work in different committees of the association of german engineers where they can discuss about new and existing technologies among experts.

High-quality, environment-friendly products and environment-friendly production

Our plants do not only stand for their quality but also for their environment-friendly production. To ensure this we use existing resources in the country of delivery to save unnecessary transportation routes. Each plant is a flagship for german technology and quality.

Our history


Since the foundation in 1986 we continuously expanded our scope of supply and improved the used technologies. We especially delivered pioneer work with the introduction of the biofilter technology for the removal of diverse odours which in the end led to its breakthrough.

Expert knowledge

Everything started with one process engineer. Today, we employ engineers with a wide variety of qualifications. We ensure the adjustment of our knowledge to technical and legal innovations with ongoing professional development to at the same time conserve and update our long-term experience.

Service network

Today, based on the headquarter in Viernheim, we have an international network of cooperations and sales agents. This brings us in the position to offer our services internationally and to be able to answer professionally to client specific questions and problems.


Now and then the state of the technique has not been a fixed-point but rather a development process. Together with renowned research institutions and through our own analyses with our mobile and stationary pilot plants, we ambitiously solve difficult and novel waste air problems.


Our products are subject to an ongoing quality control that ensures a long lasting, trouble-free operation of our plants.


Become a part of our great team! Our engineers and natural scientists have long-term experience and a wide variety of qualifications in various areas (process engineering, biology, chemistry, material science, mechanical engineering, electrical engineering, etc.).
