GEG-compliant, subsidy-eligible systems for maximum efficiency and minimal emissions
Sustainable air handling doesn’t start with the unit – it starts with the overall concept. At Rox, we combine highly efficient components, intelligent control technology, and future-proof interfaces into customized energy-saving concepts. Whether it’s heat recovery, demand-controlled fan technology, free cooling, or integration into building management systems – our solutions enable energy-optimized, regulation-compliant operation and sustainably reduce operating costs. We ensure compliance with all relevant regulations: from the German Building Energy Act (GEG) and the EU Ecodesign Directive (ErP) to the Federal Funding for Efficient Buildings (BEG) for non-residential properties. Our systems are demonstrably efficient – and often eligible for subsidies.
Furthermore, the acquisition cost of an air handling unit must always be evaluated in relation to its operating costs over the entire service life – a consideration that can vary greatly depending on the perspective of planners, system builders, or operators.
We provide comprehensive support: Our in-house energy consultants help you identify suitable funding programs and, if desired, assist with the application process.
In addition, we place great importance on sustainable materials, low-maintenance design, and life cycle optimization – for resource-efficient air handling solutions that already meet the demands of tomorrow.
