Sustainability
RESPONSIBILITY IS PART OF OUR TRADITION
As a family-owned business, HUBER & RANNER has always been driven by long-term thinking. Responsible business is not an additional promise — it shapes how we engineer our products, operate our facilities and make investment decisions.
We combine economic strength with responsible use of resources, durable engineering and a clear commitment to our employees and future generations.
FIVE PILLARS. ONE RESPONSIBLE APPROACH.
Our approach is built around five areas that translate responsibility into practical action and guide our daily decisions:
1. PRODUCTS & SERVICES
Choosing HUBER & RANNER means investing in efficient performance, durable construction and material-conscious engineering.
- Efficiency: Our air handling units can be configured for high levels of energy recovery and low power consumption in accordance with project requirements. Combined with demand-based operation, this can help reduce the energy required for building ventilation and climate control.
- Longevity: Robust construction, high-quality components and service-oriented engineering are designed to support a long operating life. Numerous installations in our reference portfolio have been operating reliably for more than 20 years.
- Material recovery: Material selection is considered from the design stage. Approximately 95% of an air handling unit’s weight consists of metals that can generally be recovered and recycled through established recycling processes at the end of the product’s service life.
2. ENERGY USE IN PRODUCTION
We focus on the areas we can directly influence: electricity procurement, efficient facilities and the continuous improvement of our production processes. Our environmental management system is certified according to ISO 14001.
- 100% renewable electricity: We source 100% of the electricity purchased for our German production sites from certified renewable electricity sources.
- Efficient facilities: We continuously monitor and improve the electricity consumption of our production facilities. Efficient building technology, modern equipment and optimised processes help reduce the energy required to manufacture our air handling units.
3. WASTE PREVENTION AND MATERIAL USE
For HUBER & RANNER, waste prevention begins with design and production planning. Precise manufacturing processes and optimised material use help reduce scrap and avoid unnecessary waste.
Materials are separated systematically during production and directed towards reuse or established recycling processes wherever technically feasible. The objective is clear: use materials efficiently, minimise production waste and retain valuable resources within the material cycle.
4. MOBILITY
We are gradually transforming our company mobility. Electric vehicles are being introduced into the HUBER & RANNER fleet where they meet operational requirements. When charged at our German production sites, they use electricity sourced from renewable energy.
This step forms part of our ongoing effort to reduce the use of fossil fuels in areas that we can directly influence.
5. EMPLOYEES AND SOCIAL RESPONSIBILITY
Long-term business success depends on people who take responsibility, contribute ideas and develop their expertise. HUBER & RANNER promotes a working culture built on initiative, collaboration and mutual respect.
- Working environment: We invest in ergonomic workplaces, modern working conditions and well-designed break areas in both production and administration.
- Health and wellbeing: Workplace improvements, selected health initiatives, food options and free mineral water support our employees throughout the working day.
- Development: Practical training, personal responsibility and opportunities for professional development strengthen expertise within the company.
ERWARTEN SIE MEHR. Responsible Thinking. Engineering for the Future.
LONG-TERM THINKING
As a family-owned company, HUBER & RANNER makes decisions with the future in mind. We are convinced that economic strength, technological progress and responsible use of resources reinforce one another — and we continuously develop our operations in this direction.

Product Brochure and Service Centres
Our commitment to quality is not just a theory—it is the foundation of our corporate policy. This is demonstrated by our rigorous standards and confirmed by numerous certifications from accredited testing bodies.
ISO 9001 & PÜG Certification As our certification body, PÜG offers comprehensive expertise in auditing management systems for quality, environment, and occupational safety. Our certification according to DIN EN ISO 9001 reflects our extensive know-how in the design and production of air movement products. This ambitious standard places our products, services, and—above all—customer satisfaction at the center of Huber & Ranner’s quality policy.s.
RLT-Herstellerverband (AHU Manufacturer Association) Huber & Ranner is a long-standing member of the “Herstellerverband RLT-Geräte e.V.” (Association of AHU Manufacturers). The association’s goal is to promote air handling technology at the highest technical level, drive standardization, and foster innovation.
Hygiene Certified (ILH Berlin) Modern Air Handling Units must ensure hygienic indoor air quality. Without proper design and maintenance, ventilation systems can become a breeding ground for microbial growth. With extensive expertise in ventilation hygiene, the ILH Berlin certifies that Huber & Ranner products meet the strictest hygienic requirements (e.g., VDI 6022), ensuring safe and clean air operation.
For exports to Russia and the Eurasian Economic Union, strict regulatory standards apply. Huber & Ranner holds the necessary certificates (such as GOST-R / EAC) to comply with local consumer protection and safety laws, ensuring a smooth import process for your projects.
Service We remain at your side even after delivery. Flexible and straightforward, we offer individual, all-around service for the entire lifecycle of your unit.
