With Bosch Rexroth’s CytroBox, the future of Industrial Hydraulics has begun.

Connecting machines and facilities with IT systems opens up enormous potential for more economical and intuitive processes. This is exactly where Bosch Rexroth‘s new CytroBox hydraulic power unit comes in. With its intelligent, energy-efficient modular design, CytroBox provides a new solution for the medium performance range up to 30 kW. With its integrated IoT technologies, CytroBox is paving the way for consistently implementing Industry 4.0 concepts.

CytroBox is a hydraulic power unit for applications in the medium performance range up to 30 kW. The current consumption is parametrized and optimized with regard to the existing electrical cabinet. Pre-set controllers in variable-speed pump drives adjust energy requirements on an individual basis.

The speed is switched off during no load in order to save energy and is controlled under full load in a closed loop to the exact pressure command value with a highly dynamic response. This saves up to 60 percent of energy compared to conventional power units. The high efficiency of the manifold block, which is manufactured using the 3D sand core printing method, also contributes to overall efficient operation. Made via additive manufacturing, the manifold block is up to 40 percent more compact and boasts improved flow channels. This improves oil flow, reduces pressure losses and minimizes the areas where leaks could occur because fewer plug screws are required. The hydraulic power unit is also equipped with an active dewatering unit to protect against external contamination.

Cleverly connected to condition monitoring

Equipped with a sensor package and open interfaces, CytroBox is ready for use in connected environments. Integrated and wired sensors provide information regarding the current filter, oil or drive condition. The collected data is then processed by the drive controller. With the help of Open Core Interface, data can be further processed and integrated into modern machine concepts.

CytroBox also offers a connectivity option for operators. This makes it easy to realize the potential of IoT technologies as a pay-per-use service easily and without risk. All information regarding CytroBox – from the component and operating status or forthcoming maintenance work to predictive maintenance analyses is available via Rexroth’s Online Diagnostics Network (ODiN). As a result, the information is always close to hand.

Full performance with the smallest footprint

Flexibility and space-saving designs are important criteria when selecting components. The CytroBox combines a small footprint with a compact design. This also includes a tank with optimized de-gassing and flow. Thanks to a CFD simulation, the oil volume is reduced by 75 percent – going from 600 liters to a mere 150. The use of synchronous technology also saves space. The high-performance, water-cooled synchronous motors are up to 80 percent smaller than comparable asynchronous ones. All functions are brought together in a compact control cabinet. As a result, CytroBox can easily be integrated into existing production lines in a flexible, space-saving manner.

Lower noise emissions for improved worker comfort

Airborne sound is completely absorbed by the compact arrangement of components in one unitary housing and built-in sound insulating mats. This design ensures no sound leaks out. In order to reduce noise emissions stemming from structure-borne noise, the motor pump group is rigidly affixed to a polymer-concrete foundation. The damping bearings that would typically transmit the noise to the tank are completely eliminated. Even at a full load, CytroBox’s noise emission is less than 75 dB (A). Comparable power units have an average noise level of 85 dB (A). This reduces the need for additional noise reduction measures, lowers costs and makes the work experience more pleasant, even when in direct proximity to the hydraulic power unit.
