Everything you need, everything networked - the radically new hydraulic power unit for machine tools

Bosch Rexroth CytroPac

The compact power unit integrates with all machine tool concepts in a space-saving manner.

In response to the decrease in installation space required by modern hydraulics, Bosch Rexroth introduces its new small power unit, the CytroPac. With CytroPac, Rexroth integrates hydraulic components with a frequency converter, motor, 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.

Installation space is valuable in machine tools as the overall footprint is important to the buying decision for operators. The newly developed hydraulic power unit CytroPac from Rexroth integrates all hydraulic and electrical components using minimum space. The compact 20 liter tank greatly contributes to these small dimensions. It ensures correct degassing of the oil and, as a result, prolongs the service life of the fluid.

Energy consumption cut by up to 80 percent

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. At the same time, speed control in line with demand reduces the heat input into the oil, thereby reducing cooling requirements. Cooling is also enhanced via integrated heat pipe technology - an innovative, space-saving solution for cooling by means of water.

As a decentralized intelligent unit, the frequency converter, which is integrated in the housing, communicates with the machine control over the common real-time Ethernet interfaces Sercos, PROFINET, EtherCAT, EtherNet/IP, and Modbus/TCP, as well as PROFIBUS. Commissioning is simplified because the only connections required are to the power supply and the communication with the control, as well as to the hydraulic circuit and the cooling water circuit.

Networked via open interfaces

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.

The housing insulates all sources of noise to the outside. Machine manufacturers no longer require additional, space-consuming and expensive housings in order to comply with international and automotive regulations with regard to permissible noise emissions. The small power unit features protection class IP 54.
