Marine Dynamometers. It's where we started.

Froude’s involvement with the marine industry dates back to the mid 19th century and the origins of the company when William Froude invented the world’s first hydraulic marine dynamometer for testing marine steam engines. 

Our low-speed dynamometer (LS) specifically designed for marine engines benefit from well over one hundred years of experience in understanding and meeting customer requirements and expectations in this industry. The award-winning LS series of dynamometers with its unique three-load cell system eliminates trunnion bearing loss and allows the carcass to float and move with the oscillations of the prime mover. This eliminates the requirement for driveshafts and their associated alignment requirements. The LS dynamometers are suited for engines from 9 MW up to 75 MW.

Lower powered high-speed diesel marine engines can be tested using our F series of dynamometers.

In addition to our Aerospace and Industrial gas turbine test systems, Froude equipment is also available for Marine gas turbine applications using our renowned ‘F’ and ‘HS’ type dynamometers with the Texcel VX200 controller which provides unequaled performance and control. 

The high-performance demands of engine development, production and overhaul are ably met with equipment that includes a standard range of engine test stands and adapters that may be tailored to individual requirements.

Froude produces low-speed, very high power dynamometers for use with steam turbine and gearbox applications as well as for capital ship and cathedral engines. In fact, we are world leaders in the design and production of large dynamometers for testing piston, turbine and electric prime movers for the marine industry. We have a unique design which allows for simplified maintenance and vastly reduced installation time.
The Froude HS Range of hydraulic dynamometers have been specifically designed for gas turbine testing, and are compact, robust and low maintenance. The HS125, HS150 and HS2600 have a one-piece rotor shaft manufactured from a unique stainless steel forging. 

Designed for turboshaft and turboprop engine applications, each featuring interchangeable engine adaptor frames allowing several engine types to be tested on a single test stand. Well-proven standard products are available for the majority of turboshaft and turboprop engines. 

Froude dynamometers are high-performance machines and well known for their consistent high level control throughout the speed range. This is achieved through the innovative engineering behind our water outlet valve, rotor and stator design. We offer a system that is of high quality, easy to use and competitively priced. You will find Froude testing equipment throughout the world--the product of choice for gas turbine OEMs, MROs and test facility suppliers. 
F Type hydraulic dynamometers are designed for high accuracy of control, torque measurement and rapid load changes (response). Our range includes low speed, high torque variants for turboprop testing and higher speed, lower torque variants for turboshaft testing in uni- and bi-directional configurations. 
The VX200 builds upon the success of the VX100 PRO controller which has operated in test cells throughout the world for more than a decade. Specifically designed for testing gas turbine engines, the VX200 includes control and signal conditioning circuits for the dynamometer and associated hydraulic power packs and flywheel.

Running on the latest version of MS Windows, the Froude VXI graphical user interface provides clean visualization of dynamometer data on user-customizable pages. Responsive control is offered through a simple ergonomic desktop controller or customer host interface.
