Controllable pitch propellers
Heimdal propellers are designed using modern software and customized according to the requirements of each vessel. This is to ensure a high degree of efficiency and to minimize noise and vibrations.
Heimdal propellers are designed to achieve the highest possible pull from the engine. With 15 hub sizes to choose from, the blades are tailor-made to suit each vessel. All blades are designed by modern computer programs, and are properly balanced to give correct resistance to the servo system.
Three-bladed propellers
Three-bladed propellers offer the best efficiency at the lowest price. They are used on fishing vessels, tugs and other vessels where the hull design allows for a larger diameter.
