The DS2R electro-hydraulic controller features proportional valve technology and replaces the DS1 model. It is fitted directly to the secondary control unit—axial piston equipment that can serve as both a pump or motor to manage variations in torque on winch drives in rotary AHC systems. The controller offers
- high dynamic response;
- precise, accurate motion so the loaded winch cable remains continuously “idle”—moving up and down only according to the winch, not the surface wave motion;
- energy efficiency through better control of hydraulic components, including the ability to use hydraulic accumulators to recover and reuse up to 70% of the secondary control unit’s installed power; and
- more reliability and easier maintenance, with a simpler design that eliminates a sandwich filter and is less prone to contamination.
