OJ-DRHX RS-485 & Analog control Flexible DRHX with Sophisticated Software
The OJ-DRHX RS-485 & Analog control is equipped with both Modbus RTU, BACnet MS/TP and an 0-10V interface for controlling, making it the perfect choice for refurbishment and much more.
OJ-DRHXEnergy-efficiency through accuracy
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.
Modbus RTU, BACnet MS/TP & Analog control
This is the high-end variant of the DRHX family. It is equipped with both Modbus RTU, BACnet MS/TP and 0-10V interface for controlling. It include a display with 3 x 7-segment for giving user information of actual performance and error messages. This variant is the perfect choice for refurbishment.
