Sleipner Side-Power Thruster Systems

• Noise reductions of up to 75% measured in controlled environments
• The expected and tested normal noise reduction in "average installations" 20-40%
• Upgrade kits are available for most “SP” series thrusters with special adaptors

• Provides delay between drive directions
• Monitors solenoid functions to reduce the chance of solenoid lock-in
• Will stop the thruster in case of a locked-in solenoid, without extra user action and even without controlling a main switch.

The thruster gear leg 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

Sealed gear leg with long-life “mechanical” seal where highly polished ceramic and carbon surfaces form the only moving sealing surfaces, ensuring protection against damaging water intrusion into the gear leg. Pre-filled with special gear oil for lifetime lubrication.

• "Mechanical" seals with surfaces of ceramic and carbon for ultimate security against water intrusion

A properly engineered single propeller system will be the most energy efficient thruster. Its compact design fits easily into narrow bows making it the perfect match for our smaller models. With more than 60.000 single propeller thrusters in use, the Side-Power single series system has proven its eliability.

The twin propeller system can give more thrust than a single propeller system in the same tunnel diameter. This is our choice for our mid-range models where high thrust is equired in a small tunnel diameter. Due to the compact design and high performance, the twin models have become the thrusters of choice among boat builders around the world.

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.

The gearhouse / drive legs of most Side-Power DC Electric thrusters are now fully galvanically isolated / separated from the electric motor and motor bracket. This ensures that even if there is an accidental short circuit or a current leak for other reasons, the immersed parts are not effected as they could be with direct electric contact.

To provide reliable and safe thruster installations in more boats, we offer modified versions of our DC electric thrusters in watertight housings for use in stern and other locations that may get wet or be exposed to gasoline fumes. These thrusters are fully ignition protected (ISO 8846) for use in boats with gasoline engines. Theyhave a hermetically sealed composite housing around all electric parts. This provides the ignition protection as no gasoline fumes can enter and be ignited by sparks.
The other advantage is that the electric parts that could be damaged by water are also covered and protected, making these thrusters the ideal choice for other stern thruster installations where it is difficult to ensure that the thruster will always remain dry.

S-link is a "CAN" based control system with full intelligent communication between all units in the system, much like a computer network. Main advantages include:
- Round, compact and waterproof plugs with unique keying and color coding to avoid faulty hookup
- Unlimited number of commands or information transfer on a single cable
- User feedback at panel - Intelligent troubleshooting.

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