Electric motors for extreme environments -40°C to +120°C-1

CAST-IRON CASING took into account the most extreme operating conditions, I.S.G.E.V.s engineers were able to design electric motors to satisfy the needs of even the most demanding customers. Thanks to the all cast iron, high-quality construction, this series of motors can operate in environ- ments with temperatures down to Җ40C or up to +120аC with 100% relative humidity. The toughest challenge for an electric motor is epitomised by the environmental conditions, since extreme temperatures, high humidity and aggressive agents really put motor relia- bility to the test. Only motors that have been specially designed to withstand such extreme conditions can guarantee a truly extended ser- vice life.
