Profile: Interpower International Ltd manufactures industrial, marine and bespoke generators from 2kVA to 4000kVA. We offer a range of industrial generators, both open and acoustically treated, for use in all types of applications, including factories, hospitals, airports, government buildings, data centers, and banks. Our soundproofed sets are available with noise levels as low as 65dBA at 1m. Rotary UPS system uses stored energy in a rotating flywheel, directly coupled to an alternator permanently in synchronism with the utility. In the event of an outage, the stored energy provides the power, until the engine has started, and is up to speed, at which point the mechanical coupling between the flywheel and the engine is closed.
