SIMOTICS HV C flameproof

Unbeatably compact – extremely reliable

SIMOTICS HV C flameproof

SIMOTICS HV C flameproof is the new ultracompact flameproof high voltage motor, which ensures maximum safety and very reliable operation, even in highly explosive environments. The reason for the unique power density is a revolutionary cooling concept. This combines the principle of air circulating in the motor – together with tube cooling elements: Further, the SIMOTICS HV C flameproof sets itself apart as a result of its extremely rugged design for maximum reliability, even under harsh conditions, optimized vibration behavior – as well as extremely short delivery times and high on-time delivery for this power class.
