Bow Thrusters

Product catalog summary

Introduction
Zf Marine, a leading supplier of propulsion systems, has introduced a new line of electric bow thrusters designed to enhance performance with increased thrust, reduced noise, and extended operation under heavy duty cycles.

Specifications

Thrust: The bow thrusters feature counter-rotating propellers and a patented tapered-tunnel design, providing up to 20% increased thrust across the operational range. Special five-blade, skewed propellers enhance efficiency and reduce noise, improving comfort and maneuverability.
Noise Reduction: The innovative tunnel design minimizes cavitation, reducing noise by up to 10 dB (A), making it significantly quieter than existing installations.
Duty Cycle: Equipped with electronically controlled AC motors, these thrusters are suitable for heavy duty applications, offering continuous thrust for up to 30 minutes without overheating. Proportional control ensures precise maneuvering and minimizes battery load.

Technical Data
The ZF bow thrusters are compatible with the ZF Joystick Maneuvering System, enhancing maneuverability and comfort. The technical specifications for different models are as follows:

Model	Tunnel Diameter (mm/inch)	Props	Electric Motor Power (kW/hp)	Thrust (kg/lbs)	Voltage (V)
ZF BT-E 185/6 TP	185 (7.3)	Twin Counter Rotating	6 (8)	105 (231)	24
ZF BT-E 250/10 TP	250 (9.8)	Twin Counter Rotating	10 (13)	230 (501)	48 *
ZF BT-E 300/15 TP	300 (11.8)	Twin Counter Rotating	15 (20)	315 (694)	48 *

* 48V motor. The bow thruster includes a 48V-24V series-parallel battery switch box.
