5.1 Performance description
The CytroBox is a drive system for hydraulic machines in modular design, which was
developed as a decentralized hydraulic supply unit for general machine construction
for the medium performance range from 7.5 to 30 kW.
All built-in components of the CytroBox, such as the flow-optimized downsized
tank or the compact synchronous motor, are combined in one housing which can
be integrated in existing production lines in a space-saving manner thanks to its
small footprint.
The powder-coated housing is sound-insulated and equipped with an integrated
polymer concrete foundation with drip pan and drain function.
The aluminum mounting bracket used enables flexible connection of
accessory components.
The airborne sound is absorbed by the compact arrangement of all the components
in one housing and the built-in sound insulating mats. In order to reduce noise
emissions stemming from structure-borne noise, the motor-pump assembly is rigidly
affixed to a polymer-concrete foundation. Consequently, the noise emission of the
CytroBox is less than 75 dB(A) – even at full load!
The drive controller of the variable speed pump drive ensures dynamic adjustment
of the power/speed and the flow to current requirements to reduce the operating
costs. Consequently, the speed is reduced under partial or zero load to save energy
and increased under full load with a highly dynamic response. This saves up to
80 percent of energy compared to constantly driven hydraulic power units.
The control cabinet is air-cooled and the synchronous motor is water-cooled.
Optionally, the hydraulic fluid is cooled by a circulation circuit with a plate heat
exchanger.
The hydraulic power unit requires a cooling water connection.
The oil temperature can be set by means of parameters.
