reproductive health, diabetes or osteoporosis patients. In January 2021, Sulzer bought Nordic Water, a leading supplier of water treatment technology. The acquisition strengthened Sulzer’s wastewater treatment offering and provided further access to the clean water market, a fast-growing segment where Sulzer has already been present for years. In September 2021, Sulzer spun off its Applicator Systems division to create medmix, unlocking significant value for shareholders. medmix is a global leader in high-precision delivery devices, listed since October 2021 on the SIX Swiss Exchange with an enterprise value of roughly CHF 2 billion. Since the spin-off, Sulzer is once again a pure-play flow control company with a strategic focus on the Water and Renewables markets. Rail traction Sulzer developed a series of rail traction engines in the 1930s and 1940s which were used extensively in diesel locomotives in the UK, Europe and South America. A small number were used in locomotives in Africa and Australia. The Sulzer LDA (prefixed by the number of cylinders, and with a suffix related to the cylinder bore) engine was widely used by British Rail and Romanian Railways. Many were built under licence by Vickers-Armstrong at Barrow as six-, eight- and twelve-cylinder form, and in Romania, by Reșița works for Electroputere Craiova. The twelve-cylinder engine was used in the British Rail Class 47, Romanian Railways Class 60/62, Polish Railways Class ST43, China Railways ND2, and several others. The 12LDA28 engine was a double bank engine having, in effect, two six-cylinder engines side by side, rather than a V-type as favoured by many other manufacturers. Sulzer V-type engines for rail use bore the type number LVA (with a 50-degree angle between the banks). In the late 1970s, locomotive rebuilder Morrison Knudsen installed a series of Sulzer power units into several existing locomotives. The first applications were of the marine based 6ASL25/30 & 8ASL25/30 series used in a Morrison-Knudsen demonstrator and four M-K TE70-4S units for the Southern Pacific. This was merely reworking of an existing design into a new application Ten 16 ASV25/30 power units were installed into locomotives belonging to the Atchison, Topeka & Santa Fe and the Union Pacific. Teething problems plagued these machines and their operation in revenue earning service was brief. Research into correcting their problems continued but was eventually curtailed by Morrison Knudsen late in 1982. These power units were descendants of the LVA range.
