The transport of people and goods by land, water and in the air requires sustainable propulsion concepts. Thanks to our technological expertise, unique knowledge of materials and innovative power, Sealingtechnologies offers the aerospace, shipping and rail industry high-quality solutions that are innovative and economically efficient. Sealing Technologies sets the course for the future with its components for use in electric mobility and complete battery and fuel cell systems for ships and trains. Sustainability is also in the spotlight in recreational vehicles, thanks to emission-reducing components from Sealingtechnologies.
Aerospace is a trendsetter when it comes to innovation. Air traffic is becoming faster, safer and more efficient. The performance of the aircraft increases, while at the same time the footprint of flying must be reduced in terms of sustainability. As a result, aircraft fly higher and higher in increasingly cold air layers; at the same time, their engines operate at extremely high temperatures with environmentally friendly “lean” fuel mixtures. In addition, alternative fuels are becoming increasingly important on the road to sustainability towards carbon-free aviation, a long-term goal of the International Air Transport Association (IATA).
These trends are full of technical challenges and are tailor-made for a company that specializes in technology such as Sealingtechnologies. Whether it's new materials, lightweight components, advanced designs or innovative technologies, our global aerospace expertise means we have the right sealing solutions at hand. In this way we give the entire industry a boost to fly into the future.
The quality, safety and reliability of our products are of particular importance given the extreme demands placed on seals by the aerospace industry. People's lives depend on it. We have unique materials expertise, innovation, operational excellence and innovative simulation and testing capabilities to meet all industry specifications, whether for temperature and media resistant standard parts or tailor-made individual solutions. All over the world, in all relevant markets.
The requirements for performance and reliability are even higher at sea than on land. This fits perfectly with the technological competence of Sealingtechnologies.
Today, approximately 15,000 large merchant ships, cruise ships and icebreakers operate with the seals supplied by Sealingtechnologies. We offer complete solutions for propulsion and steering systems (including engines, thrusters, rudder systems, stabilizers and more) from a single source and put together sealing packages that are optimally matched in terms of material and functionality. In many cases, customer-specific special solutions in special sealing materials and large dimensions are required.
Extremely long maintenance intervals are essential for the economically efficient operation of “floating buildings”. Here, the Sealingtechnologies products have been distinguished by their durability and first-class quality for more than forty years.
The wind is also turning in the shipping industry towards environmentally friendly, emission-free propulsion systems. Quiet, clean, sustainable and efficient is the motto on the open sea and in ports all over the world.
The first step is the introduction of methanol as a marine fuel. Sealing Technologies even goes a few steps further and equips ships with modular, individually configurable battery and fuel systems. As the highest discipline, we offer shipbuilders and shipping companies integrated hybrid propulsion solutions that optimally combine the advantages of batteries and fuel cells.
When it comes to sustainable mobility, the railways are already making progress today. In local transport, the course has been set for automation and automatic operation without a driver. Effective risk minimization during surgery requires a high degree of functional safety. The chassis with its assemblies plays a supporting role in the double sense of the word. Seals from Sealingtechnologies are rarely visible here, but they are nevertheless indispensable.
A look into the future; with powerful batteries and fuel cells from Freudenberg and combinations of both, rail vehicles are on the right track, especially on non-electrified routes and in shunting traffic. With a unique depth of added value, we offer trains complete electromobility packages from a single source: from the separator and the cell to the complete battery solution; from membrane to the stack to the entire fuel system.
Reliability plays a key role in braking, whether on trams or high-speed trains; in the freezing cold of Northern Norway or in tropical, sultry latitudes. Seals from Sealingtechnologies provide consistently high braking power and are known for their functional reliability and durability under all climatic conditions. This is based on the unique material expertise we have gained over decades. The result is materials that are individually tailored to the intended applications and work reliably in braking systems and their ancillary units around the world.
Cruising the highway on a motorcycle; traverse dusty terrain on an enduro bike or quad bike; fishing on a sport boat on the open sea; driving down the ski slope with a snowmobile, with seals from Sealingtechnologies, leisure fun goes hand in hand with driving safety and environmental responsibility. We offer a whole range of product innovations that reduce friction installation space and weight in all types of vehicles. Our sealing solutions enable shrinkage by resisting the high temperatures of engines. This reduces fuel consumption and emissions. At full power and with unparalleled driving pleasure.
Electromobility is increasing in many areas of life. The trend towards emission-free mobility is also increasingly affecting our leisure activities. Whether it concerns sealing components for batteries, fuel cells and electric motors, Sealingtechnologies not only swims with this current, but also far ahead.
For example, our innovative sealing solutions control the pressure equalization and thermal management of battery systems. They can withstand the enormous speeds of electric motors. Or they shield electronic components against disturbing electromagnetic radiation. For quiet, clean and low-emission leisure fun.
