Introduction to WARTSILA 007370035
007370035 Product Overview
The WARTSILA 007370035 is a high-reliability hydraulic control module, specifically engineered for Wärtsilä 2-speed marine gearboxes—core components in propulsion systems of ferries, offshore support vessels, and cargo ships with variable load requirements. As the “actuation core” of the dual-speed gearbox, it regulates hydraulic pressure to engage/disengage clutches, enabling seamless switching between high and low propeller speed modes without interrupting propulsion power. A standout feature is its integration with Wärtsilä’s propulsion control system (ProTouch), which automatically triggers speed switching based on real-time engine load and vessel speed data—optimizing propeller efficiency and reducing fuel consumption by up to 15% compared to single-speed configurations . Equipped with built-in pressure sensors and diagnostic logic, it monitors clutch engagement status and hydraulic oil conditions, sending fault alerts to the central control module (CCM-10) to prevent gearbox damage.
