SE20 TUNNEL THRUSTER (12V, 20KG)
Description
SE20 Tunnel thruster, 12V 20kg thrust ON/OFF
The world's leading series of bow and stern thrusters for leisure boats are the SE series from Sleipner. Sleipner offers the world's largest range of DC thruster systems for leisure boats.
All the approved features and well-known quality boat builders around the world value, are now available for even smaller vessels.
With the new SE20, we add yet another tunnel diameter to our extensive program. With a tunnel diameter of only 110mm, the SE20 is suitable for vessels up to 23 feet depending of the vessels windage area. As with all the other thruster models in the SE series, the SE20 also offers tremendous installation flexibility, as the thruster can be installed upon the tunnel in any angle and the thruster motor can be rotated on the motor bracket in 90 degrees steps.
The SE20 are galvanic insulated as the larger thrusters in the SE series and features Sleipners patented IPC technology for intelligent power control and safety.
The SE20 is only available for bow installation.
Properties
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.
DC
Powered by direct current.
ANALOG
Sleipner analog signal cables with Plug & Play connectors are color-coded to match the wiring diagrams with high-quality connectors to ensure a correct installation.
OVERHEAT PROTECTION
Automatic detection of overheating of internal components. When an unsafe temperature is detected, the unit is automatically shut off to prevent overheating.
GALVANIC SEPARATION
Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.
SEALED DRIVE LUBRICATION
The thruster gearleg is pre-filled for lifetime lubrication and sealed using a long-time mechanical seal with ceramic and carbon surfaces for ultimate security against water intrusion.
SINGLE PROPELLER
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 thruster range. With more than 60.000 single propeller thrusters in use, the single propeller has proven its reliability.
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
INTELLIGENT POWER CONTROL
Sleipner's patented intelligent power control provides a minimal delay between drive directions to reduce wear of the mechanical parts while monitoring solenoid functions. In the case of a solenoid lock-in, the thruster will automatically stop without extra user action or controlling the main switch.
