CPR: the next generation hydraulics
CPR-systems represent a fundamental shift in how hydraulic power is delivered and controlled
Built on proven engineering principles
CPR-systems rely on traditional hydraulic components, including modern accumulators, coolers, safety valves, and fixed displacement pumps as fundamental parts. At its core, the hydraulic transformer uses the proven Floating Cup technology.
What sets CPR-systems apart
CPR-systems outperform conventional hydraulics in efficiency, sustainability, and operational control. Off-highway machinery demands more, and these systems deliver.
The FCT45 makes it possible
The FCT45 hydraulic transformer is the enabling technologyCPR-systems represent a fundamental shift in how hydraulic power is delivered and controlled
How the transformer changes everything
The FCT45 transforms how hydraulic power distributes through the system. It manages pressure and flow with intelligence that conventional components cannot achieve.
Technical breakthroughs that define the next generation
CPR-systems introduce capabilities that reshape how off-highway machinery operates. Each innovation builds on the others to create a complete solution.
Energy recovery systems
Captured energy that would otherwise dissipate now returns to the system for productive use.
Modular architecture
Components integrate seamlessly, allowing customization for specific applications and future upgrades.
Robust precision control
Real-time adjustment ensures optimal performance across varying operating conditions and load demands.
What makes CPR systems more efficient?
There are several reasons why CPR-systems are much more efficient than current valve controlled systems, like load-sensing systems.
Dissipation is replaced by transformation
The transformers replace the proportional valves. Energy dissipation is replaced by transformation, which is in principle lossless.
Energy recuperation
Contrary to valve controlled systems, the energy can be recuperated by means of the transformers. The regenerated hydraulic power can send to other users, or stored in a hydraulic accumulator.
Efficient power supply
In CPR-systems, the expensive and inefficient variable displacement pumps are replaced by simple and extremely efficient fixed displacement pumps.
Power management
The accumulators in the CPR-system create the opportunity for power management. The motor and pump can always be operated at the best operating conditions.
CPR-systems deliver measurable improvements over conventional hydraulic technology
These metrics represent real-world performance gains that manufacturers can expect. The numbers reflect what early testing has shown in a real wheel loader application.
