SAC360 tunnel thruster Ø300mm 230V

The Sleipner SAC360 (item code SAC360/300-C-2-H) is a 230 V AC tunnel thruster delivering 360 kg of thrust, designed for continuous operation as a bow or stern thruster. It is mounted horizontally and suits boats of 18-33 m (59-108 ft), including commercial and industrial vessels in constant operation.

Key features

• Twin counter-rotating propellers for maximum thrust in a minimal tunnel diameter
• Q-PROP five-bladed skew propellers: up to 75% noise reduction measured in controlled environments, 20-40% expected in average installations
• PRO variable speed control with hold-thrust function; suited to joystick interaction
• S-Link CAN-based control system with waterproof, keyed and colour-coded plugs; allows AC and hydraulic thrusters on one common control cable
• Flexible coupling compensating for minor misalignment between motor and gearleg
• Flexible installation at any angle on the tunnel
• Gravity feed lubrication from a reservoir above the waterline for oil level monitoring

Delivery scope

Supplied as a complete ready-to-install kit, configured for the specific vessel with no further VFD setup required:

• PDC-301 Drive Controller (Modbus link to VFD, real-time data logging, fault history, firmware upgrade via S-Link)
• Variable Frequency Drive (VFD); low-harmonic VFD option reduces total harmonic distortion to less than 5%
• Gearleg with propellers and bracket
• Flexible coupling
• AC motor
• EMC filter

Applications

Bow, stern and tunnel installation on commercial vessels, motor boats and sailing yachts of 18-33 m.
