Electric actuators Rematic Ex in explosion-proof version are designed for applications in the environments with potentially explosive atmosphere, as well as actuators Standard Ex. The actuators are certified in accordance with a valid directive 94/9/EC and standard EN/IEC 60079-0, 60079-1, 60079-7, 60079-31 as well, for the environments with potentially explosive atmosphere. They are controlled by electronic control system DMS3 – REMATIC. Larger types of actuators with a three-phase motor can be equipped with reverse contactors or contactless switching. They are installed mainly at modulating operations in an explosive environment with duty cycle S4-25%, 90 - 1200 c/hour.
