Serving our customers: 100 years of knowledge transfer

How does a company like Sulzer succeed in asserting itself on the market for over 185 years, continuously creating innovative products? What influence does the transfer of knowledge have, and how does the curiosi- ty of employees influence knowledge transfer? What will the knowledge transfer of the future look like?

In 1919 — 85 years after the company was founded — Sulzer’s first customer magazine was published in French. Since then, the Sulzer Technical Review has provided technical informa- tion on Sulzer’s current product range without interruption. The magazine’s 100th anniversary gives us a glimpse into the history of Sulzer as well as the future of knowledge transfer.

Networks for knowledge transfer in pre-industrial times Professional networks are not an invention of our contemporary age. In earlier centuries in Johann Jakob Sulzer (1806–1883) Europe, craftsmen acquired knowledge within the family business, then moved on foot from shop to shop to learn additional skills. Before the Sulzer brothers (Fig. 1) established their new foundry (Fig. 2) in Winterthur in 1834, they collected technical and craft expertise in Switzer- land, France and the Kingdom of Bavaria through apprenticeships. Johann Jakob Sulzer’s journey led him from Bern and Lyon to Paris between 1827 and 1830. Salomon Sulzer apprenticed in Munich, Ulm and Guebwiller in Alsace.

Pioneering achievements thanks to a fascination with technology As early as 1839, the Sulzer brothers used a steam engine instead of horsepower to drive the foundry’s bellows. The Sulzer company was intensively involved with steam because of its founders’ enthusiasm for new technology. This was not only used as a working medium for power transmission in the foundry; energy transmission by steam also led to the develop- ment of new, innovative products. Sulzer was a Swiss pioneer in boiler construction and heating technology. The company built the first large, steam-powered central heating system in 1841 (Figs. 4 and 5).

Success thanks to recruiting the best talent The Sulzer brothers recognized early on how important the skills and knowledge of their employees were for new developments and improvements within the company. In the early nineteenth century, England was a pioneer in the fields of steam engines, tool construction and mechanical engineering. During a trip to England, Johann Jakob Sulzer met the young engineer Charles Brown (Fig. 6) and recruited him, along with his knowledge, for steam engine construction in Switzerland.

At Sulzer, Brown enjoyed a great deal of freedom and was able to creatively translate his in-depth knowledge and wealth of ideas into numerous new designs, improvements in operations and new products. Sulzer built its first steam engine with 2.2 kW (3 hp) in 1854. Brown’s persistence and perfectionism led to the centrifugal valve control and thus to an increase in performance and safe operation of the steam engine. The Sulzer valve steam engine (Fig. 7) already had 121 kW (165 hp) in 1865 and was awarded first prize at the 1867 World Exhibition in Paris. Sulzer thus gained worldwide renown and even granted manufactur- ing licenses to partner companies to manufacture the steam engines around the globe.

In 1878, a young, talented student completed an internship at Sulzer and got a taste of industrial work. His name is world-famous today: Rudolf Diesel (Fig. 8). After applying for his patent for the diesel combustion engine in 1893, he offered it to Sulzer for use. Sulzer thus established an extremely successful mainstay and produced diesel engines from 1898 until 1997. Fig. 9 shows the assembly hall for diesel engines in 1909.

Discovering new talent and using the energy as a driving force is a skill that is still held in high regard in the Sulzer Corporation today. Close connections and cooperation with leading universi- ties worldwide not only open up access for Sulzer to the latest knowledge, but also to the talent pool of bright minds in the fields of science and technology.

Why asking questions is so important People who have children know how the desire for knowledge expresses itself. Children ask questions non-stop. And one can encourage this curiosity in life by patiently and competently answering all these questions. It’s not always easy, but answering children’s questions is akin to making an investment in the future. Asking questions, questioning, thinking, acquiring and deepening knowledge, allowing new connections to form in the brain, being open to inspiration – the development of new ideas and solutions is based on these abilities of the human brain.

Neuronal plasticity is the ability of the brain to rewire nerves via the synapses and to come up with new thoughts. Many questions do not just promote the transfer of knowledge from one person to another; questions help employees to think more flexibly, which in turn boosts the flexibility of the entire company. The role of innovation in the company’s history and corporate culture influences a company’s success more than is generally thought to be the case. A corporate culture that knows about the creative power of inquisitive, thinking employees allows and rewards change. Companies with this type of culture always find new ideas, ways to optimize, and new market niches – partly also through the acquisition of other companies – to create lasting success. Sulzer employees value this creative freedom, which paves the way for perpetual renewal and innovation.

Energy supply as a driver of innovation Sulzer established itself in the energy supply sector long ago with its valve steam engine and steam heaters. A look at the technological history of the last 200 years shows how rapidly energy technologies have changed. Numerous groundbreaking product developments and patents in this field originate from Sulzer. From the very beginning, Sulzer has distinguished itself by rapidly implementing the latest scientific findings and offering reliable, tested and safe processes. 7 Serving our customers: 100 years of knowledge transfer Sulzer Technical Review 3/2019

From the water mill to solar energy At the beginning of the industrial revolution, grain mills, sawmills and forges were mainly driven directly by water wheels, partly also by windmills, and later by steam engines (optimized by J. Watt in 1765). Generators (1866) powered by steam engines or hydroelectric power supplied electricity for the first electric motors in the factories. This was followed by thermal power stations, in which fossil fuels such as coal, oil or gas generated steam, which in turn was used to drive steam turbines and generators. After the expansion of the power grids and electrifica- tion (around 1880), the electric motor finally established itself as a universal driver for stationary applications. With the invention of the combustion engine (1807 – F. I. de Rivaz) and the diesel engine (1893 – R. Diesel), power generation became economical even in smaller units, and automobiles conquered the roads of the world. The civil use of nuclear energy through nuclear fission (1938 – O. Hahn/F. Strassmann) led to the construction of nuclear power plants. Today, renewable energies have come to the forefront — energy from biomass, geothermal energy, ocean energy from the tides, wind energy and solar energy.

Sulzer was involved in all of these advances, such as steam engines, turbines, generators and pumps for storage power plants, as well as heavy water distillation technology for nuclear power plants. Sulzer is considered a pioneer in Swiss economic history due to the speed with which the company has translated technical innovations into technically mature, reliable product develop- ments. Electric motors were used in Sulzer pumps as early as 1894, four years after the introduc- tion of high-voltage electrical networks. Only five years passed between the licensing and market launch of the first 14 kW (20 hp) diesel engine in 1898. Diesel ship engines were introduced in 1904, and the first diesel locomotive in 1912 already had 882 kW (1’200 hp). Sulzer’s high-­ performance pumps were essential for equipping the first hydroelectric reservoir power plants. As early as 1904, a 590 kW pump was used for this purpose.

Today, Sulzer is involved in the development of technology for renewable energies, be it separation technology for renewable energies with microbes or molten salt pumps used in parabolic solar power plants.

The following listing shows how the focus of Sulzer’s main activities changed during the course of the company’s history: foundry 1834–1993, pumps 1834–today, services 1834–today, heating and air-conditioning 1841–2001, thermal power systems 1841–1997, steam engines 1854–1952, vessel manufacturing 1867–1934, rock drilling and tunneling 1876–1905, refrigeration systems 1877–2001, piston compressors 1878–2002, diesel engines 1898–1989, water turbines 1911–1999, locomotives 1912–1998, production of thermal turbo­machinery from 1939–2001, waste combustion plants 1941–1994, jet engines 1945–1999, textile machinery 1952–2002, chemical process engineering 1956–today, applica- tor systems 1958–today, medical technology 1962–2001, electronics 1963–1999, paper machinery 1966–2006, surface technology 1985–2013, fuel cells 1997–2005.

Knowledge transfer through expert systems and artificial intelligence The knowledge transfer of the future will be determined by the conventional exchange of information and increasingly by big data. Data acquisition systems such as BLUE BOX™ will help to analyze existing data from pumps and pipelines. The data analysis algorithms are based on the expert knowledge of Sulzer’s leading minds, gained over many years of experience. Customers benefit from this know-how without realizing it.

With the Industry 4.0 concept, for example, knowledge transfer takes place with the help of RFID chips in the products, which can transfer different settings. The product-specific expert knowledge is transferred to the chip and used.

Knowledge transfer for optimal collaboration The transfer of knowledge has changed over the centuries. The well-founded training system for employees at Sulzer began as early as 1850 with the founding of a home for apprentices. Another milestone was close cooperation with the newly founded technical universities in Zurich and Lausanne, which continues to this day. Sulzer makes use of the scientific opportunities offered globally by cooperating with institutes and universities. Only those who implement the latest scientific findings, and do so quickly, can stay ahead of global competition. In addition to product innovation, this also includes production techniques, material knowledge, organizational forms and digitalized processes.

Sulzer Technical Review – 100 years of knowledge transfer The first customer magazine was published in 1919 to make it easier for Sulzer’s customers to understand complex technical interrelationships. The magazine promoted Sulzer’s technical achievements, patents and development progress, as well as making it known to the public. Since then, Sulzer’s Technical Review has been a source of knowledge for people with a wide range of technical interests. But it’s not just customers who have subscribed to the Sulzer customer magazine: For decades, technical universities in particular have been consulting the foundational knowledge provided by Sulzer. Numerous libraries worldwide carry the Sulzer Technical Review (Fig. 11).
