Avec son impressionnant volant d\u2019inertie de 3 tonnes, le moteur Winterthur a \u00e9t\u00e9 restaur\u00e9 par Divonnelectro. Au d\u00e9but, il fonctionnait au gaz pauvre, ensuite au benzol qui a \u00e9t\u00e9 supprim\u00e9 parce que canc\u00e9rig\u00e8ne. Maintenant il fonctionne \u00e0 l\u2019essence 95.

\u00abIt's very rare to find equipment and the building that houses it virtually intact. This factory represents a complete panorama of hydraulic, thermal and electrical energy\u00bb. (Claude Welty, Director of the Mus\u00e9e Electropolis in Mulhouse from 1997 to 2023, during his visit to the Moulin David in 2004). \u00abUntil 1950, Divonne was self-sufficient in energy, either through paddlewheels supplying mechanical energy directly to workshops located on the course of the Divonne, or through power stations located on the same river\u00bb. (Georges Leskens, president and founder of Divonnelectro) Some images of the machines and the various collections at the Moulin David. Francis turbine and dynamo group - 1930 Dynamo with multiplier Characteristics: Type B7.42 - 52kW - 108\/110 V continuous 1,050\/1,100 rpm. Shunt excitation Manufacturer: Constructions \u00e9lectriques d'Ani\u00e8res Giovanelli et Tiranti. Dynamo and turbine restored by Divonnelectro. On the left is the flywheel that opens the Francis turbine's guide vanes and sets it in motion. Winterthur auxiliary power unit - 1907 With its impressive 3-tonne flywheel, the Winterthur engine has been restored by Divonnelectro. At first, it ran on lean gas, then on benzol, which was withdrawn because it was carcinogenic. Now it runs on 95 petrol. The combustion engine runs on compressed air. A new compressor was installed in 2019. The old compressor has been kept in the corner. It dates from the same period, 1907. You can admire the Winterthur engine in operation during the Divonnelectro demonstrations. John Jacob Rieter converter set with dynamo from Winterthur - 1902 The converter set restored by Divonnelectro, in working order. The 1902 dynamo is the oldest machine in the Moulin David hydroelectric plant. The town of Divonne sent 440V DC from the municipal power plant at Pont des Iles to the Moulin David. The converter transformed it into 110V DC. Marble switchboard - 1930 A key feature of the plant is the marble switchboard, which is in a perfect state of preservation. It includes: -the inputs for the production and storage systems on the two panels on the right: turbine dynamo - Winterthur engine dynamo - converter - batteries - the outputs for the power supply (light and power) of the three hotels: Grand Hotel, Chicago and Golf on the three panels on the left. The diaries Several diaries from the 40s and 50s, in which Soci\u00e9t\u00e9 des Bains employees recorded their activities, are on display at the Moulin David. They started at 5.30am or 6am, depending on the season, and finished at 11pm or 11.30pm, including Saturdays and Sundays. Maintaining the hydroelectric plant and its canal (charging the battery - dismantling, cleaning, maintaining and repairing the machines - maintaining the workshops - collecting rainwater to fill the battery, etc.) Maintaining and repairing the lamps and chandeliers, and the electrical appliances (ice machines, hoovers, etc.) in the major hotels. Provision of cinema screenings at the theatre, owned by the Soci\u00e9t\u00e9 des Bains.
