The intelligent controller for rotary heat exchanger with RS485 Modbus communication

RHX2M is a step motor system designed for accurate, silent control of rotary heat exchangers in ventilation systems. The RHX2M step motor system provides even torque throughout the entire speed range of 1 to 200 rpm. The rotor can therefore be accurately controlled over a wide operating range, resulting in energy-optimised heat recovery and precise temperature control. RHX2M is suitable for either conventional systems with 0-10 V control or more advanced systems with Modbus control, such as the OJ Air2 system from OJ Electronics.

  • For use with conventional systems with 0-10 V control and advanced systems with Modbus control
  • Even torque throughout the entire speed range of 1-200 rpm
  • RS485 Modbus communication
