Frese FUELSAVE® - Intelligent FlowManagement for Marine Fuel Savings
Overview?Frese FUELSAVE® is a patented, energysaving solution designed for marine cooling water systems. By combining dynamic control valves, frequency converters, sensors, and automation in a fully managed installation package, FUELSAVE® optimizes flow and temperature control to significantly reduce pump and boiler energy consumption onboard vessels

How It Works
Dynamic pressure independent valves continuously adjust flow based on real-time system demand, eliminating overflow and preventing excess pumping energy.
Integrated automation and frequency drives ensure precise temperature and flow regulation across seawater and freshwater cooling loops.
Turnkey retrofit implementation includes mechanical and electrical installation, crew training, and remote performance monitoring for ongoing optimization

Key Benefits
Substantial Fuel & Energy Savings
Pump energy reductions of 50-70?%, depending on operational mode
On DFDS ferries Luna Seaways and Aura Seaways, FUELSAVE® delivered 48?% savings at sea and up to 71?% in port, translating to 130 tonnes of fuel and ~404 tonnes of CO? saved annually on just one vessel.
Additional reductions in boiler fuel consumption (??0.25?tonne per port call) were achieved using Frese’s OMEGA Compact 3way rotary valve to regulate condensate temperatures
Improved Regulatory Compliance
Helps improve vessel carbon intensity indexing (CII) scores and supports compliance with EEXI, FuelEU Maritime, and IMO emissions mandates
Fast Payback & Scalable Design
Typical ROI within under two years, depending on vessel type and operation pattern frese.uk.
Compatible with a wide range of ship types (RoPax ferries, WTIVs, container ships, tankers, etc.), and flexible enough to adapt to system modifications or expansions.

Ideal Applications
Cooling water circuits in engine rooms
Heat recovery systems needing precise flow and temperature balancing
Retrofit projects seeking turnkey energy-efficiency upgrades

8. Notch-wire inserts – highest quality and economically efficient
VTE maintains a wide range of notch-wire inserts. In addition, VTE also stocks spare parts such as gaskets and valves for many Asian brands. While European manufacturers produce filters with wire mesh, Asian manufacturers prefer a method in which a fine steel wire is wound around a cylindrical frame.
Notch-wire inserts are used by Asian manufacturers. The difference lies in the construction of the filter inserts, which are made by wrapping thin stainless steel wire around a cylindrical frame.
Notch-wire inserts from VTE are compatible with all common Asian manufacturer brands and offer an optimal price-performance ratio. At the same time, the high quality of VTE’s notch-wire inserts promises an equally long service life – and thus high cost-effectiveness.
VTE only requires the dimensions from the spare parts list. This way, a quotation tailored to your needs can be prepared.
