    When solvent emissions occur in production processes, exhaust air systems are used to comply with statutory emission limits. The STEAG subsidiary Krantz GmbH produces these systems and now has the ‘SmartRTO’ in its portfolio, an innovation that Stefan Gores has developed together with his team.


    Profile
    Stefan Gores (57) studied mechanical engineering at the Technical University of Aachen (RWTH). After graduating, he started his professional career in the development department of Krantz in Aachen in 1990. In 1993 he became head of research and development in the field of environmental engineering. Since 2002, he has headed the Clean Air Solutions division at the STEAG subsidiary and is a sought-after speaker and author as an expert for industrial exhaust air treatment. He is named as the inventor in 18 patent specifications.

    RTO stands for regenerative thermal oxidizer, a system for treating exhaust gases. What are the particular advantages of a SmartRTO?
    Large exhaust air systems are highly complex and we design individual solutions for each customer, depending on local conditions and requirements such as the volume and degree of pollution of the air to be cleaned. For smaller systems, on the other hand, a standard solution is often sufficient. This is the SmartRTO, which our customers value in many respects: We can reduce manufacturing costs by using standardized components.

    In addition, due to its small footprint and relatively low weight, we can transport the turnkey SmartRTO by road, rail or ship. A further advantage is that the exhaust fan and all additional components required for operation are already integrated into the system design. This design idea enables us to commission the SmartRTO before it leaves our production shop. Our customers only have to connect the media supply on site.

    Are the SmartRTOs exactly the same for all customers, then?
    No. Despite standardization, customers can select certain SmartRTO features or add individual modules to the system. It is a modular system, so to speak. The basic variant consists of three system sizes for a maximum exhaust air flow volume of 5,000, 10,000 and 20,000 cubic meters per hour. Customers then select the appropriate variant. They can also have additional components installed, for example for heat recovery.

    How do you assess the market potential of your innovation?
    Our systems are used in many parts of the world in a wide variety of industries and production processes. When painting, printing, coating, cleaning or gluing – solvent emissions occur everywhere and must not be allowed to escape into the environment. Our systems are needed to prevent that. I am proud of our team performance, which enables us to offer innovative solutions to our customers. At Krantz, we have an impressive reputation for reliability and energy efficiency. The SmartRTO also has convincing advantages, which is why I am very optimistic that it will quickly be accepted by our customers. In China, we are already marketing the SmartRTOs quite successfully through a licensee.
