During the Monaco Yacht Show the Yersin research laboratory yacht, which is equipped with Bernard Controls electric actuators, was presented. More than 80 weatherproof quarter-turn actuators figure on all circuits onboard (ballast, water, cooling).
For the ballast system especially, products of the Failsafe spring-return FQ range have been selected. For this critical process, the selection of an automatic return in security position (opened or closed valve, depending of the initial setting) in case of a power cut has been decisive.
On the other circuits, weatherproof quarter-turn actuators – OA/AS models (now gathered under the SQ range) have been selected to operate butterfly valves. This travel ship, built by the PIRIOU chantiers in Concarneau (Brittany), and belonging to a Frenchman, will be a laboratory designed to navigate on all world’s seas, included in polar area. This ship itself was named after Alexandre Yersin (1863-1943), doctor, bacteriologist and French-Swiss explorer, to whom we notably attributed the discovery of the bacillus responsible for the plague and subsequently the elaboration of the first worldwide serum aimed at healing this disease.
