Cytrocore

Function

The CytroCore for Hydrogen is a compact, high-performance servo-hydraulic drive system fitted with software and a CGV compressor Cylinder (ATEX) making it for dry-running reciprocating hydrogen compressors. It integrates hydraulics, electrics, controls, software, and an ATEX-certified compressor cylinder into a single solution for easy system integration. Using an SHP4V pump unit with an A4VZA pump and variable-speed servo synchronous motor, it delivers precise, dynamic compressor control, ensuring high gas-side efficiency at elevated pressures and operating frequencies. The system can generate forces up to 2,500 kN and speeds up to 0.8 m/s for maximum compressor performance.

Advantages

The CytroCore for Hydrogen combines a compact 0.5 m² footprint with integrated hydraulics, electrics, and control systems, requiring only 26L of oil. Despite its small size, it delivers 90 kW peak power, 60 kW continuous power, flow rates up to 227 L/min, and operating pressures up to 315 bar. Efficiency is maximized through primary displacement control and A4VZA pump technology, reducing energy and flow losses. The SHP4V servo-hydraulic pump unit provides rapid response with short acceleration and deceleration times, while a noise-optimized design ensures low sound emissions. Integrated condition monitoring enables real-time operating data, and the standardized, pre-tested system reduces installation effort, space requirements, energy consumption, and overall operating costs.
