SAC2200 is a high‑performance thruster delivering up to 2200 kg of continuous thrust, approved for installation on DNV‑classed vessels.
Its compact design combines high efficiency with low noise and vibration, ensuring smooth and precise maneuvering. The thruster features a highly efficient twin counter‑rotating NiBrAl Q‑propeller system and a lead‑free aluminium bronze gear leg for maximum durability and corrosion resistance.
SAC2200 is supplied with an external 2.5‑liter gear oil tank with oil level sensor, allowing oil changes while the vessel is in the water. An optional gear oil temperature sensor is available.
The unit is offered in versions for horizontal or vertical installation.
For optimal system integration, please contact Sleipner or an authorized distributor for project support.
Product Description

Each thruster is configured specifically for the vessel. No further setup or settings of the VFD (Variable Frequency Drive) are required.
System overview

S-Link™
The innovative S-Link™ control system ensures a quick and trouble-free installation. The system also monitors the operating condition of the thruster and provides continuous feedback to the operator.
S-Link™ also offers the advantage of combining AC thrusters and hydraulic thrusters, all connected to a single common control cable and with the possibility of variable speed control of the thrusters.
The AC thrusters are designed based on many years of volume production of our other thruster series, which has resulted in a series of cost-effective products with high quality. All AC components are supplied by branded manufacturers to ensure quality, high operational reliability, and easy access to spare parts worldwide.
The standard range is designed for 230V or 400V systems but can also be supplied for other specifications on request.
Low Harmonic VFDs
In addition to standard frequency drives, we can supply systems with “Low Harmonic VFD” for installations with specific requirements for THD (Total Harmonic Distortion).
A system with a standard VFD will create a certain level of distortion to the AC network. A system’s actual THD (Total Harmonic Distortion) will vary depending on other loads, available generator capacity, total generator capacity, etc.
Sleipner systems with a low harmonic VFD will reduce the harmonic distortion to less than 5%, which will give the following advantages:
- Keep the electrical network clean
- Reduce the risk of disturbance
- Prevent damage to other equipment
- Prevent interference with communications equipment
- Reduced need for oversizing of the generators
PDC-301 Drive Controller

- Communication with VFD by Modbus connection
- Included 3-wire cable for connection to VFD Modbus terminals
- Improved monitoring and diagnostics simplifies commissioning and troubleshooting by real time data logging and readout of historical faults.
- Firmware upgrade through S-Link™

Properties
S-LINK™
S-Link™ is a CAN-based control system used for communication between Sleipner products installed on a vessel.
- Compact and waterproof plugs
- Keyed and color-coded connectors to ensure correct and easy installation
- Different cable lengths, extenders and T-connectors makes the system scalable and flexible to install
Q-PROP™
The Q-PROP™ has measured noise reductions of up to 75% in controlled environments. The five-bladed skew propeller reduces noise levels while maintaining exceptional efficiency. Some thruster models even see an increase in thrust power.
- The expected noise reduction in average installations: 20-40%
- Upgrade kits are available for most Sleipner thruster models with special adaptors
PRO™
A PRO™ thruster system enables you to apply only the necessary power to complete your maneuver. The variable speed control eliminates the noise associated with standard on/off thrusters.
The system also includes a practical hold-function. In a dual system (bow and stern) a single press of a button will keep you alongside the docks – making docking truly a one-person job.
Speed controlled thrusters are the best choice for joystick interaction.
HOLD-FUNCTION
Docking your vessel has never been easier. With a single press of a button, you can rely on your thrusters to maintain the boat controlled against the dock while stepping off to secure the lines — making docking truly a one-person job.
OVERHEAT PROTECTION
When high temperatures are detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating power to maintain temperature within safe levels.
FLEXIBLE INSTALLATION
Sleipner offers installation flexibility to work with the space you have. Our thruster models allow installation at any angle on the tunnel, tailored to fit any space available in your vessel.
GRAVITY FEED LUBRICATION
The thruster gearleg is supplied with oil from a separate reservoir above the waterline to monitor oil levels.
AT SEA SERVICE
This product can be delivered with an optional on-water oil change capability to limit the need for dry-docking your vessel for a scheduled oil change.
TWIN COUNTER-ROTATING PROPELLERS
Two counter-rotating propellers offer the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. Our twin-counter thruster range is the favorite among leading boatbuilders in high-end yachts.

What is the S-link control system?
S-link is a Sleipner CAN BUS based control system with full intelligent communication between all devices within the system, much like a computer network. It is used for all retract thrusters and Pro thrusters with a DC control system.
Main advantages include:
- Round, compact and waterproof plugs with unique keying and color coding to avoid faulty hookups.
- An unlimited number of commands or information transfer on a single cable.
- It has user feedback to panel
- Intelligent troubleshooting
