Fire protection systems for industrial plants must provide security at all times – including in the event of earthquakes. Full safety is provided by KTI spring isolators of the newly developed GB series.
KTI Schwingungstechnik Dipl. Ing. Rolf Trautmann GmbH has developed its own series of spring isolators, which provide seismic protection of fire extinguishing systems. One KTI customer from Bremen, for example, supplies extinguishing systems for protecting industrial installations and buildings throughout the world. These fire protection systems are installed in containers. They also have to remain operable even in the event of earthquakes. The connection to the machine must not be broken or damaged in case of such a disaster. The KTI solution for this requirement: The containers are mounted on KTI spring isolators of the GB series, which reduce seismic acceleration. An integrated viscose damping reduces shifting.
The KTI customer indicates the location and weight of the machines to be secured. On the basis of these factors, KTI then calculates the design and configuration of the spring isolators. In addition, SDA Engineering, an engineering firm associated with the Technical University RWTH Aachen, issues a verifiable certificate for the KTI design for the customer in the form of a time history analysis under earthquake loading at the location of the plant in question. KTI rendered systems safe from earthquake damage in this way in the following countries: Algeria, Nigeria, Iraq, Russia, Egypt, Iran, Peru, Thailand, Kuwait, India, Australia, Bolivia, Bahrain, Mexico, Angola, Switzerland, Spain, Libya, China, Chile, Venezuela, Tanzania, Columbia, Turkey.
KTI, however, does not only supply spring isolators for seismic protection of fire extinguishing systems. Seismic protection of industrial plants, machines and buildings is provided by individual KTI vibration elements such as spring isolators, tuned mass dampers and vibration dampers. The configuration and design are oriented to the vibration profile of the relevant earthquake location.
This aspect of its product programme was presented recently by KTI at the International Conference on Seismic Design of Industrial Facilities held at RWTH Aachen, where in late September 2013 140 experts from 17 countries discussed the challenges of earthquake-resistant design of buildings. The aim of the conference was to facilitate dialogue between research and practical applications.
