SH420 Tunnel thruster

PROportional

A PROportional speed controlled thruster system allows for more precise handling of the boat in all conditions, applying only the necessary power needed to complete your maneuver confidently.

By limiting the power under normal weather conditions, noise levels are significantly reduced. The system also includes a practical HOLD-function in a twin thruster system. With a single press of a button, the bow and stern thruster will keep you alongside the docks - making single handed docking very easy indeed! Proportional thrusters are also the best choice for joystick interaction.

A DC Speed Control system contains three main elements - proportional control panels, a power control unit and a DC electric thruster - all tied together with the new S-link™ control system. The thrusters used in a speed control system are almost identical to the familiar SE range of DC thrusters, the only difference being the addition of a temperature sensor and a new electronic control box. All mechanical and main electric parts are from the well proven thruster range produced by Side-Power for many years.

All 12 & 24 volt DC electric thrusters produced by Side-Power can be enabled for DC Speed Control by authorized Side-Power service personnel, even the oldest models.

S-link™

S-link™ is a CAN-based control system with full intelligent communication between all units in the system, much like a computer network.

• Round, compact and waterproof connectors with unique keying and color coding to avoid faulty hookup

• Unlimited number of commands or information transferred on a single cable

• User feedback at panel

• Intelligent troubleshooting

Twin Counter-Rotating Propellers

Two counter-rotating propellers can give the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. The TC models are the favourite thrusters among leading boatbuilders for their high-end yachts.

External oil tank for easy access

The thruster gearleg is filled with oil from a remote reservoir located above the waterline. This generates overpressure, making an effective seal against water intrusion in the gear leg.

• Separate oil reservoir placed above the waterline

• Allows easy access for oil changes

• Having the advantage to be able to change oil in units used commercially, with hundreds of running hours per year

Q-prop™

The new 5 blade special skew propellers are the result of over 2 years of development work and thousands of tests. They have been designed to reduce the noise level, while maintaining the exceptional efficiency of the old 4 blade Side-Power propellers. This goal was achieved, and we even chose to make them a little bit more aggressive on some models, increasing the thrust on some thrusters about 5%. Please see individual information on each new thruster for more details.

• Noise reductions of up to 75% measured in controlled environments

• The expected and tested normal noise reduction in average installations: 20-40%

• Will be delivered on all Side-Power models except models with 300mm and 385mm tunnel diameter

• Upgrade kits are available for most SP series thrusters with special adaptors
