Trawl door TWISTER

The Twister was first launched in 2020 as manual trawl doors and immediately became a success. Since then, Twister doors have consistently demonstrated superior spreading force, stability, and flexibility over previous designs. With the integration of active control technology, the Twister doors evolved into semi-automatic trawl doors. This functionality allows operators to preset specific depths, ensuring precise and reliable performance. Now the third generation of Twister trawl doors from Vónin is on the market. These can be controlled directly from the bridge of the ship. This innovation offers complete command over the trawl doors, enabling seamless and dynamic adjustments in real-time. Three different configurations: 1 / TWISTER MANUAL DOORS: These trawl doors boast exceptional spreading force, have remarkable stability and high flexibility. Adjusting the doors spreading force manually is simple thanks to the shutter system. 2 / TWISTER SEMI AUTOMATIC DOORS: With all the features of level one, these doors also integrate active control, allowing you to preset a specific depth from the bridge and making them semi-automatic. 3 / TWISTER FULLY CONTROLLABLE DOORS: Including all the same features as in level one and two, this advanced level gives you full control of the trawl doors by sending commands directly from the bridge to the Twister smart doors. The shutters system shutters that alter the flow of water passing between two of the sets of foils, with each door fitted with upper and lower shutters. This offers settings for greater or lesser spreading force, while also providing options for the doors to be set to seek up or down in the water column.
