Hoyer VMS EnergyEdge
Variable speed drives, sensors and automation that match engine room fan and cooling pump speed to actual demand; stated 40–65% energy reduction.
Description
Hoyer VMS EnergyEdge, also referred to as the Hoyer Energy Saving System (ESS), combines variable speed drives, sensors and automation. It analyses real-time data and adjusts the speed of fans and pumps via frequency converters to match operating speed, water temperature and ventilation requirements, supporting IMO compliance.
Key features
- Variable speed drives, sensors and automation in one system
- Real-time adjustment of engine room fans and cooling pumps
- Stated energy reduction of 40–65%, depending on application and operating conditions
Customer case
A European shipowner retrofitted 4 engine room fans, 3 seawater cooling pumps and 3 LT freshwater cooling pumps. The retrofit saved 1,416,832 kWh/year and 290.5 tons/year of fuel, cut CO₂ by 628.4 tons/year, and paid back in 1.65 years.
Applications
Newbuild and retrofit installations on engine room ventilation fans and seawater and freshwater cooling pumps.
