WF Series
WF 350 - 580 | 544 - 1,449 kW
Robust, efficient and sustainable, the REINTJES WF Series fulfills the requirements of modern propulsion concepts with increased input speeds, higher reduction ratios, lower weight, and compact dimensions. Modular PTO/PTI-ready configurations support hybrid drives, batteries, generators, and auxiliary hydraulic loads.
Strong, Light, Small and Fit for Future Propulsion
The WF Series combines compact dimensions, lower weight, higher input speeds, and reduction ratios up to 8:1. Its modular architecture is designed to support efficient marine propulsion today and easy hybrid retrofits tomorrow.
More Power, Less Weight
More power at lower weight and reduced space volume helps lower installation cost while increasing payload and engine-room flexibility.
Higher Reduction Ratios
Increased input speeds and higher reduction ratios help lower propeller speed, improving efficiency and contributing to reduced fuel consumption.
PTO/PTI Ready
Modularized PTO/PTI options support hybrid systems, electric drives, batteries, hydraulic pumps, generators, and future retrofit flexibility.
Hybrid Retrofit Capability
Standardized REINTJES PTO/PTI interfaces allow auxiliary-drive retrofits or full hybrid-system upgrades as vessel propulsion requirements evolve.
Duty Cycles
The WF Series can be applied across a wide range of operating profiles, from heavy-duty commercial service to intermittent pleasure applications.
Continuous Duty
Medium Duty
