8440-2052 H

Main features and advantages:

Engineered for the unique demands of hydrogen fuel systems, the WOODWARD8440-2052 H offers significant real-world advantages. Its precise fuel metering capabilities reduce hydrogen waste by up to 15% compared to generic fuel control systems, as it optimizes delivery to match engine load exactly—lowering operational costs and maximizing the efficiency of this valuable fuel source. The module’s built-in safety features, including redundant shutoff valves and continuous leak monitoring, minimize the risk of accidents, reducing liability and ensuring compliance with strict hydrogen safety standards.​
Maintenance teams benefit from the module’s comprehensive diagnostic suite, which provides real-time alerts for potential issues such as pressure regulator drift or sensor calibration errors. This proactive monitoring reduces unplanned downtime by allowing technicians to address problems before they escalate. Additionally, the WOODWARD 8440-2052 H’s design simplifies retrofitting into existing systems, enabling facilities to transition to hydrogen fuel without extensive overhauls of their control infrastructure, saving both time and capital investment.

Installation and maintenance:

Before installing the WOODWARD 8440-2052 H, verify that the hydrogen supply system’s pressure rating matches the module’s 0-10 bar input range—exceeding this can damage internal components. Ensure the mounting surface is properly grounded to prevent static buildup, a critical safety measure with hydrogen systems. Check that the control system’s firmware supports OPC UA or PROFINET for seamless communication; older systems may require a protocol converter.​
For ongoing maintenance, conduct monthly inspections of all electrical connections to ensure they remain tight, as loose connections can generate sparks—a serious hazard with hydrogen. The module’s status LEDs should be checked weekly: a steady green light indicates normal operation, while a flashing red light signals a safety interlock activation requiring immediate attention. Calibrate the flow sensors annually using Woodward’s hydrogen-specific calibration tool, and update the module’s firmware during scheduled shutdowns to access the latest safety algorithms. In outdoor installations, inspect the module’s enclosure quarterly for signs of corrosion, which can compromise its integrity.
