Energy-Saving System
Hoyer ESS helps marine customers reduce energy use, lower emissions and improve efficiency
while supporting reliable vessel performance at sea.
Optimise vessel fuel consumption with Hoyer VMS ESS
Reduce your onboard energy consumption, lower your carbon footprint, and comply with IMO regulations.
By combining VSD's, sensors, and automation, Hoyer ESS can reduce your marine application's energy consumption with 40-65%.
Hoyer VMS ESS
Data-driven energy control
By combining variable speed drives (VSDs), sensors, and automation, Hoyer ESS helps reduce energy consumption and optimise the operation of cooling pumps and engine room fans.
The system uses real-time data to adjust fans and pumps according to actual operating demands such as sailing speed, water temperature, and ventilation requirements. This helps lower fuel consumption, reduce emissions, and improve efficiency in operation.
