Bosch Rexroth Hydraulic Power Unit CytroPac

Bosch Rexroth introduces all new small power unit, the CytroPac. With CytroPac, Rexroth integrates hydraulic components with a frequency converter, Hydraulic motor, Hydraulic pump and sensor technology in one housing to form a cabinet-free power unit. As an “out-of-the-box” solution, the new series dramatically simplifies and speeds up commissioning. Further, by matching speed control to demand, CytroPac is also capable of reducing energy consumption by up to 80 percent. At the same time, the decentralized, intelligent hydraulic power unit senses all operational states and fits into Industry 4.0 concepts with condition monitoring options. CytroPac covers the power range up to 4 kW and flows up to 35 l/min.

CytroPac is based on the Sytronix drives from Rexroth. The integrated frequency converter automatically controls the motor speed according to the current demand. Compared with constant power units, energy requirements can be reduced by 30 to 80 percent depending on the cycle characteristics, while the power output remains unchanged. This helps machine manufacturers comply with the European Ecodesign Directive 2009/125/EC on energy consumption and CO2 emissions, as well as the even more exacting requirements of the automotive industry.

CytroPac is already designed for the increased information demands of Industry 4.0. Its core is the integrated frequency converter: Ready-to-use, wired to sensors for pressure, temperature, oil level, clogging and flow, it provides the machine control with data over a Multi-Ethernet interface. Since operational states are continuously acquired, wear and faults can be recognized at an early stage and quickly eliminated. Moreover, operators can change pressure and flow over the Ethernet connection in real time - regardless of their location
