Widely used in the nuclear power industry, where superior reliability is required

Nuclear

The nuclear power industry requires products that demonstrate excellent lubrication performance under harsh conditions and are capable of providing superior reliability. Represented by MORESCO HIRAD, we offer a range of synthetic lubricants with a structure that can withstand exposure to radiation. These products are employed in vacuum oil and gear oil used under high-dose irradiation in particle accelerators, bearings in remote handling equipment and seismic isolation equipment, and other applications, and have earned a stellar reputation.
