LYEN Controllable Pitch Propeller – Low pressure Low noise

Rating from 200kw ~ 20,000kw

LYEN has technical advantages for a more reliable Controllable Pitch Propeller with excellent performance.

Propeller Hub

▶ 3 blades, 4 blades and 5 blades are available for different types

    of vessel and requirement

▶ In-house design for cylinder bolts means minimal hub resistance

    and benefit for less cavitation

Large piston, low working pressure and heavy duty design lead to much less risk of oil leakage and allow the system to work in a worse condition.

Blade Design

Propeller model test for 2700ml RORO vessel -Propeller efficiency up to 71% with Pressure Pulse lower to 1.27 KPa

The vessel with LYEN Propeller will achieve higher speed with less fuel consumption. Meanwhile, the noise and vibration is lower due to lower pressure pulse and working pressure. Therefore, LYEN propeller will have longer life and shorter downtime due to LYEN's technical advantages and blade design.

The blade design is tailor-made for each project. LYEN hydrodynamic experts will look into details for each project and make sure each propeller has great efficiency with appropriate cavitation and pressure pulse.

Oil Distributor

▶ The Oil Distributor is to transfer the hydraulics and lub. Oil from the Power Unit to the propeller hub.

LYEN OD has a space-saving design, easy installation and maintenance.LYEN Unique self-lubricated hub design for long-term operation and minimizing downtime.
