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

The Piranha is a high-precision 5-axis CNC machining center built for large workpieces, such as patterns, molds, jigs, and prototypes. It’s also widely used in trimming large-scale composite parts. Equipped with powerful spindles and capable of working with FlexiCAM’s Advanced Control System (ACS) or industry-standard Siemens and Fanuc systems, the Piranha is engineered for high-speed, precise machining in even the most challenging materials.

With additional options such as multiple gantries, optical (laser) and mechanical probing, palette changers, and advanced dust collection systems, the Piranha maximizes efficiency and accuracy. These features are particularly beneficial in the boat/ship building industry, where even minor deviations can impact performance and safety.

The FlexiCAM Ultimate CNC machining center is a heavy-duty machine designed for high production environments, combining robust construction with a single-piece base frame. It’s suitable for both cutting and trimming sheet materials and machining larger 3D objects like molds, jigs, and prototypes. The Ultimate offers a variety of worktable designs, such as durable cast iron tables and the specialized Vilmill vacuum table.

The Ultimate is highly customizable, with options like a 4th axis (tilting spindle) and a 5-axis head, making it adaptable for intricate 3D machining. For demanding applications, it includes features like linear scales, thermal compensation, and volumetric compensation, which enhance accuracy and maintain tight tolerances.

FlexiCAM offers a unique system for aluminum stacked sheet machining, featuring a pressure foot, detagging option, and high-velocity chip extraction. This configuration minimizes debris, optimizes cutting performance, and provides a cleaner work environment.
