The OJ-MRHX stepper motor program fit together with our OJ-DRHX controller perfectly the rotary heat exchanger demands. The MRHX stepper motor enable high starting torque, an even torque curve, continuously run at low speed and comes with a smaller foot print. By use of a stepper motor there are no risk of leakage of oil nor use of any wear out components.
