  • MRHX-3P01N, 1Nm

    OJ-MRHX

    Stepper motor for rotary heat exchangers

    Along with our OJ-DRHX controller, the OJ-MRHX stepper motor program perfectly meets the rotary heat exchanger demands. Being continuously run at low speeds, the MRHX stepper motor ensures a high starting torque and an even torque curve. Also, it has a smaller carbon footprint. Using a stepper motor both eliminates all risks of oil leakage and the use of worn-out components.
