Before discussing the individual components of gas turbines in more detail, the plants which have already been built will be looked at. The first column in Table I shows plants that were built by Escher Wyss and its licensees for testing. Columns II, III and IV list industrial plants of three output categories which were ordered by customers. With the exceptions of ML-1, La Fleur and Oberhausen II, the gas turbines department at Escher Wyss designed the cycles and the turbo machinery as well as some of the devices such as coolers, recuperators and air heaters. The licensees built most of the power plants. Nevertheless, the turbo sets for some of the plants were supplied from Zurich. The table also lists the fuel type, power output and manufacturers (licensees). The table dates from 1982.

The special properties of closed-cycle gas turbines attracted companies from all over the world, which meant that Escher Wyss acquired the following licensees: GHH of Sterkrade, Germany, John Brown of Clydebank, UK, Fuji Electric of Tokyo, Japan, Mitsui of Tamano, Japan and Mitsubishi of Nagasaki, Japan. Thus, under the technical and scientific supervision of Escher Wyss, a total of 22 closed-cycle gas turbines were built in the period from 1939 to 1972. A twenty-third installation was designed by GHH itself, and the twenty-fourth was a test installation for components of the HHT high-temperature reactor project. This was a product of Brown Boveri & Cie.
