Detailed description

The Sleipner retractable thruster ERV170/250TC-24V is designed to provide precise and quiet maneuverability for vessels from 15 to 22 meters (50 to 70 feet). This 24V system delivers 170 kg (374.8 lbf) of thrust via a 250 mm internal diameter tunnel. It features a 6-phase brushless PMSM (Permanent Magnet Synchronous Motor) synchronous motor, delivering 7.30 kW (9.90 hp) with optimized power consumption and extended runtime.

Technology and Performance

The ERV170 is equipped with PRO™ variable-speed technology, enabling proportional thrust control for smooth maneuvering and a convenient dock-hold function. The Q-Prop™ technology, with its five-blade asymmetric propellers, reduces noise by 20 to 40% in real-world conditions and up to 75% in controlled environments while maintaining or improving thrust performance. Its contra-rotating dual-propeller system maximizes thrust within a minimal tunnel diameter.

Design and Integration

Weighing 83.9 kg net, this retractable thruster stands out for its compact and lightweight design, being up to 50% lighter and 40% smaller than previous Sleipner models, simplifying vertical installation. The S-Link™ CAN-based control system ensures reliable communication and simplified installation with compact, waterproof connectors. The strut is sealed and lifetime-lubricated, featuring ceramic and carbon surfaces for enhanced sealing.

Safety and Reliability

Galvanic isolation of the underwater components protects against stray currents, while overheat protection automatically adjusts or cuts power in case of high internal temperatures. The system is ignition-protected per ISO 8846 and rated IPx7 for water spray resistance, ensuring reliability in marine environments.

Expert opinion

« Mastering manoeuvrability: analysis of the retractable thruster ERV170 »

The Sleipner ERV170 retractable thruster represents a significant advance in maneuverability for 15 to 22-meter sailboats. Its compact design and 50% weight reduction compared to previous generations facilitate integration in tight spaces, particularly for vertical installation. The choice of a synchronous PMSM brushless motor, paired with the PRO™ variable-speed system, delivers remarkable control precision and a notable reduction in noise—essential for onboard comfort. This technology enables delicate maneuvers with a practical "hold" function for docking.

The integration of the S-Link™ communication system simplifies wiring and configuration with other Sleipner equipment through reliable and watertight connectors. The counter-rotating dual-propeller design optimizes thrust for a minimal tunnel diameter, a crucial advantage when space is constrained. Durability is ensured by a sealed and lifetime-lubricated strut leg, complete galvanic separation, and integrated thermal protection. For captains demanding discreet, powerful, and reliable maneuvering assistance, the ERV170 is a long-term solution that minimizes installation and maintenance constraints.

Frequently Asked Questions

Need help? Contact us

What are the main specifications of the Sleipner ERV170 retractable thruster?

The Sleipner ERV170 retractable thruster integrates several advanced technologies to optimize safety, control, and performance. These include:

Intelligent Power Control: Minimizes mechanical wear and monitors solenoid performance.Gravity Feed Lubrication: A separate oil reservoir feeds the gearcase by gravity, ensuring effective sealing and easy oil changes.Q-Prop: A five-blade skewed propeller that reduces noise by 20 to 40% while maintaining or improving thrust.Overheat Protection: Automatically detects high internal temperatures and shuts down the system to prevent damage.Galvanic Separation: All immersed parts are electrically isolated to eliminate stray currents and prevent galvanic corrosion.PRO™ Variable Speed Control: Enables smooth, silent, and precise maneuvers with variable speed, including a hold function.S-LINK™: An intelligent communication system for simplified installation and reliable control.

What is the required supply voltage for the ERV170 retractable thruster?

The Sleipner ERV170 retractable thruster is designed to operate with a 24 V power supply voltage.

What is the tunnel diameter required to install this thruster?

The Sleipner ERV170 retractable thruster is designed for a tunnel with a 250 mm diameter.

Is the ERV170 thruster compatible with a variable speed control system?

Yes, the ERV170 thruster is compatible with Sleipner’s PRO™ variable-speed control system. This feature enables more precise maneuvers and includes a hold function, ideal for integration with a joystick.

How does the Sleipner ERV170 thruster lubrication system work?

The ERV170 thruster uses a gravity-fed lubrication system (Gravity Feed Lubrication). A separate oil reservoir, located above the waterline, feeds the lower unit by gravity. This creates positive pressure for effective sealing against water and simplifies oil changes. Additionally, it features factory-sealed, lifetime lubrication with long-life ceramic and carbon seals.

Why is this thruster only available on request?

This thruster is offered only on a quote basis as it is a primary piece of equipment requiring in-depth analysis. Validation by an expert is essential to ensure proper sizing, appropriate voltage, optimal installation on your sailboat, and selection of the necessary accessories for correct and secure installation.

What protections does the Sleipner ERV170 thruster include for reliability?

The Sleipner ERV170 thruster is equipped with multiple protections to ensure its reliability and durability:

Overheat protection: Automatically detects high internal temperatures and shuts down the system before damage occurs. Galvanic isolation: All submerged parts are electrically isolated from the onboard system to eliminate stray currents and prevent galvanic corrosion. Intelligent power control: Minimizes mechanical wear by ensuring minimal delay between direction changes and monitoring solenoid performance. Safe start-up: Control panels require a two-button activation to prevent accidental starts.

Can I control the ERV170 thruster with a remote control?

Yes, it is possible to add a remote control to operate the ERV170 thruster system. This allows you to operate the system remotely, making docking maneuvers easier, especially when short-handed.
