SE250 TUNNEL THRUSTER (24V, 250KG)
Overview
SE250 Tunnel thruster, 24V 250kg thrust ON/OFF
The SE250/300TC thruster is specially built to give a maximum thrust in a minimum diameter. It is a larger thruster to suit bigger boats that allow a 300mm diameter tunnel to offer even more thrust. With the counter-rotating propellors giving a powerful 250kg thrust and 15.5hp at underload at 21v, the SE250/300TC thruster suits boats 62/80 feet in length that have 24v charging system.
SE250 is a powerful thruster with 250-300 kg thrust. Suitable for boats between 60-84 feet, depending on weight and windage area. Can be mounted in the bow and stern.
The thruster offers great installation flexibility as it can be mounted at any angle on the tunnel. Additionally, the electric motor can be rotated 90 degrees on the motor bracket.
It is galvanically isolated and features Sleipner's patented IPC technology for intelligent power control and safety. See more of the product features below.
Properties
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.
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.
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.
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.
FLEXIBLE COUPLING
Flexible coupling protects the product’s driveline by compensating for minor misalignments between the shafts of the thruster motor and gearleg.
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.
