Innovative hydraulic power supply in compact design

To think big in modern manufacturing, you must think smaller than ever before. Compact solutions are transforming the manufacturing landscape by minimizing the space required for the hydraulic supply system. While maintaining performance, reducing noise and increasing energy efficiency.

Sounds too good to be true? Well, that's exactly what BMW achieved with the help of specialist machine builder August Mössner and our compact CytroBox hydraulic power unit.

Fast, efficient and compact.

Thanks to the new Mössner transfer system, work on the engine blocks at BMW's Landshut plant has really begun to accelerate. In addition to increased speed and precision, the system offers another special feature: CytroBox, our new integrated hydraulic supply system.

Think small

Mössner had already had positive experience with CytroBox's 'little brother,' CytroPac, a small power unit used for auxiliary functions that generates up to 4kw of power. This gave Mössner additional confidence in choosing CytroBox. Mössner now needs only half the space previously required for the hydraulic power supply. In fact, CytroBox provides at least the same level of performance in an area of only half a square meter.

Think quietly

The CytroBox is also particularly quiet. It achieves no more than 75 dB (A), which means it meets the noise requirements set by BMW, even without a housing. "Even when it is running, CytroBox is so quiet that our PLC programmer chose to sit right next to it," says Marco Schulz, design manager at Mössner.

Think efficient

Michael Hüneke, project manager at Bosch Rexroth, clarifies why the need-based supply system used by Mössner is proving to be more energy efficient. "With this application, CytroBox stands still about 15 percent of the time and uses no energy. Under load, power consumption is only 80 percent of what it was with the previous hydraulic power supply, even though the installed power is the same. This means a total saving of almost one-third of the energy consumption".

Think IoT and pay-per-use ready

IoT capability was another major consideration. Integrated sensors, condition monitoring capability and the option to activate IoT services, such as predictive maintenance, make CytroBox a future-proof solution.

With the introduction of plug-and-play solutions, Mössner's days of laboriously building complex units are over. Standardization has simplified many processes, from engineering and configuration, to documentation with immediately available circuit diagrams, to fast delivery and commissioning via plug-and-play.

"Until now, the hydraulic supply system was always the last link in the chain," sums up Markus Fuchs, purchasing manager at Mössner. "Now the situation has changed: the hydraulic supply system reduces our time to market and makes our systems viable for the future, which increases the benefits for our customers."
