XSTREAM MARINE - QI SERIES MULTI-PURPOSE ELECTRIC WINCH - QI-100 / QI-500 / QI-750

Precision Oceanographic Winches for Geophysical and Scientific Research

Product Overview 

The Xstream Marine QI Series (QI-100 / QI-500 / QI-750) is a specialized line of electric offshore survey winches developed for high-precision oceanographic and geophysical applications. Designed as a robust and compact alternative to hydraulic systems, the QI series offers a "clean" electric drive that is ideal for scientific research vessels, allowing for the precise deployment of sensitive underwater instrumentation.

Whether performing CTD profiling, towing side-scan sonars (like the R2 Sonic series), or conducting water sampling with Rosettes, the QI Series provides the rapid response and fine-tuned control necessary for successful data acquisition. With its user-friendly interface and integrated safety features, it is a versatile workhorse for various deck layouts and vessel types.

Why Choose the Xstream Marine QI Series?

• Fully Electric Operation: High-efficiency electric drive eliminates the risk of oil leaks and high maintenance costs associated with hydraulic winches, making it suitable for environmentally sensitive research areas.
• Superior Cable Management: Features a precision ACME Screw level wind system as standard, ensuring that cables of different sizes are spooled evenly to prevent damage and “bird-nesting.”
• Advanced Remote Control: Every QI winch comes with a remote-control unit featuring a proportional joystick and an emergency stop. It also allows for drive start and reset capabilities directly from the remote for enhanced safety.
• Robust & Portable: Built with an integrated protection frame and grating, the QI series is designed to withstand harsh offshore conditions. Standard forklift pockets on all models ensure easy mobilization between different vessels.
• Versatile Instrumentation Support: Specifically engineered to handle the constant deployment and recovery cycles required for magnetometers, sound velocity profilers, and towed sensors.
