OJ-DRHXModbus RTU control interface
New drive for rotary heat exchangers
The DRHX is the next generation drive for rotary heat exchangers – based on all-new technology. The DRHX series covers the range from 1Nm to 14Nm with both RS-485 and analog control. You can even get a version with a 3×7-segment display.
An excellent new alternative to geared motors
DRHX is an advantageous new alternative to traditional geared motor solutions. In contrast to geared motors, which lose torque at low and high speed, the stepper motor provides even torque throughout the entire speed range. The linear stepper motor torque curve means that rotor speed can be accurately controlled throughout a much wider range. This enables energy-efficient heat recovery and more precise temperature control.
Sensorless rotation monitor
The DRHX is equipped with a sophisticated software that monitors the rotation of the rotor, which means that no physical/optical rotor guard is required (patent pending). Naturally, fewer components also means that you get easier installation. Sensorless closed-loop control Combining a high-torque stepper motor with closed-loop sensorless control brings you a unique new solution – and great efficiency: The drive uses the feedback signal from the motor to ensure that the motor gets exactly the level of current required to achieve the desired speed and torque.
This is the basic variant in the DRHX family. It only holds a Modbus RTU control interface and triple colour LED for visual information to the user. It still contains all the needed features and of course the new software rotor monitor/guard and silent motor operation.
