SIMOTICS HV C flameproof (LV version)

Maximum power and reliability – especially for converter operation

General description

SIMOTICS HV C flameproof (low voltage version) is the new ultracompact motor which ensures maximum safety and very reliable operation even in highly explosive environments.

The revolutionary cooling concept (patent pending) combines the principle of a surface cooled motor with tube cooling elements, which ensures a high power density as a result of an extreme compactness.

The SIMOTICS HV C flameproof motors are used in the widest range of industry sectors - such as oil & gas, chemical industry or Marine. In these sectors, they are used to drive pumps, compressors and fans.
