Meet VaRoM WR50DF
For Wärtsilä 50DF & 46 Engines 24/7 Autonomous Valve Monitoring
VaRoM Wärtsilä 50DF
Monitor the valve rotation speed and temperature of Wärtsilä 50DF and Wärtsilä 46 engines 24/7 with second-by-second data. Maximize operational safety and efficiency with the world's first wireless & batteryless valve monitoring sensor.
Specially developed for Wärtsilä 50DF & 46 engines, VaRoM-WR50DF features a wireless & batteryless structure to autonomously monitor valve rotation speed and temperature 24/7.
Track the effects of thermal variations occurring during gas and diesel fuel switchovers on valve rotation physics with second-by-second data, eliminating operational risks.
Transforms the Wärtsilä engine's natural vibration into electricity using patented Energy Harvesting technology. Features a 'plug-and-forget' architecture requiring no batteries or cabling.
Data is instantly transmitted over BLE to the Wi-GaTe system, and from there to Wärtsilä SCADA, HMI, or the ESCOM-es Dashboard, offering a complete Industry 4.0 experience.
High Cost of Unplanned Downtime
A valve failure doesn't just stop the engine; due to the high component costs and complex service processes of Wärtsilä engines, it leads to massive financial losses for ship or power plant operators. Manual inspections are insufficient to capture these rapid changes.
Critical Importance in Dual-Fuel Switchovers
In Wärtsilä 50DF engines, switchovers between gas and liquid fuels (Fuel Switch) generate high thermal stress on the valve mechanisms. Maintaining a stable valve rotation speed (RPM) is vital for valve seat cleaning and cooling.
VaRoM-WR50DF: Autonomous Safety
VaRoM-WR50DF continuously monitors intake and exhaust valves while the engine is running. Detecting anomalies in advance without any operator intervention, it strengthens your Predictive Maintenance strategy.
Quick Installation, Maintenance-Free Operation
VaRoM-WR50DF is fully compatible with the specific rocker arm structures of Wärtsilä 50DF and Wärtsilä 46 series engines. It mounts on the rocker arm in minutes using just three M6 bolts. Being wireless & batteryless, it completely eliminates the complexity and additional costs of installation and maintenance (wiring, cable trays, cable pulling, battery changes, etc.).
Emission and Performance Compliance
Proper valve movement maintains fuel switchover efficiency and ensures compliance with emission standards. The detailed data obtained with VaRoM helps minimize the engine's carbon footprint.
Digital Twin and Remote Monitoring
VaRoM-WR50DF is the core data provider for building the digital twin of your Wärtsilä engine. Land-based technical teams can instantly track the valve health of the entire fleet via the ESCOM-es Dashboard.
Extend the life of your Wärtsilä 50DF engines and maximize operational efficiency by switching from reactive to proactive maintenance.
Secure Your Wärtsilä Engine
Track real-time data from the heart of your engine with wireless and batteryless sensor technology.
Frequently Asked Questions
Wärtsilä 50DF engines experience highly sensitive thermal balances, especially during 'Fuel Transfer' stages. VaRoM-WR50DF captures valve rotation anomalies within seconds during these transitions, triggering warnings to prevent critical failures like valve burning, seat wear, and mechanical sticking before they happen.
Absolutely. In dual-fuel engines where flammable gases are present, conventional battery-powered sensors carry fire or explosion risks due to lithium. VaRoM's batteryless, vibration-powered structure eliminates these risks, offering the safest industrial monitoring infrastructure.
No. VaRoM-WR50DF is designed with a 'Plug & Forget' architecture. It requires no wiring connections or engine modifications. It mounts on the rocker arm in seconds using only three M6 bolts and starts sending data autonomously.
Our sensor collects valve rotation speed (RPM) and temperature data with second-by-second precision. This data is transmitted to SCADA or the ESCOM-es Dashboard via the Wi-GaTe gateway. All historical reports required for predictive maintenance are generated automatically.
The spare parts, logistics, and labor costs resulting from a single Wärtsilä 50DF valve failure are many times higher than the VaRoM system cost. A single valve anomaly detected early immediately amortizes the system's investment cost.
Yes. Full integration is provided with existing ship or power plant automation systems via the Wi-GaTe gateway using Modbus TCP/IP, Profinet, or Profibus protocols. Data is transferred losslessly and instantly to your central system.
VaRoM-WR50DF holds an IP68 protection class, making it fully sealed against salt water, oil, and extreme vibration. It demonstrates full compliance with international standards through ATEX and CE certification processes.
Yes. Thanks to the data being transferred to the ESCOM-es Dashboard infrastructure via the gateway, you can monitor the valve status of Wärtsilä engines across your entire fleet from your technical office on shore and generate historical performance reports.
