Description

ADVANTAGES AT A GLANCE • Oil-free, safe compression • Robust design • High availability • Energy-efficient drive unit • Compact footprint • Easy servicing AREAS OF APPLICATION • Hydrogen refuelling stations • Power-to-Gas • Technical gases • Airbag inflators • Hot isostatic presses • Pressure testing technology The compressor unit consists of two coaxially arranged vertical gas cylinders, each mechanically connected to and driven by a hydraulic cylinder. A space between the gas cylinders and drive cylinders safely prevents hydraulic fluid from contaminating the medium. The two drive cylinders are hydraulically coupled with each other via a connecting line. The gas cylinders are liquid cooled using an outer cooling jacket. This dissipates frictional heat and significantly extends the service life of the seal and guide systems. The hydraulic cylinders are driven by a hydraulic power unit. Systems with a regulating pump allow infinitely variable control of changes to the number of piston strokes. Changes in stroke direction are controlled by contactless proximity switches. A particularly advantageous feature is the use of a pivotable axial piston pump which allows the drive cylinder stroke direction to be changed directly by the pump itself. This creates a highly energy-efficient electrohydrostatic drive system. Due to the absence of directional control valves, which are subject to loss, the drive cylinders are pressurised directly by the hydraulic pump oil flow. This creates a robust drive system with integrated overload protection.
