From hydraulic systems for solar trackers of photovoltaic or thermodynamic panels, to control units with Hart protocol for valve control in Oil & Gas systems, to hydraulic industrial brake systems for windmills, Hydronit has field-tested solutions. The Smart programmable digital hydraulic control unit (SPU) can allow total control of the application in a safe way (SIL2) by detecting up to 12 external sensors and controlling up to 12 on-off or proportional solenoid valves (PWM) without the need for external drivers.
