- Treatment Carrier X Series
Engineered for versatility, the X Series handles various sections of the ship, including vertical surfaces and other hard-to-reach areas, delivering thorough and precise cleaning.
- Treatment Carrier D Series
Effective on hull bottoms and other hard-to-reach spots, the D Series ensures thorough and precise cleaning — 3,000 bar, 1.3 to 13 m working height and up to 50 m²/h derusting efficiency.
- Treatment Carrier P Series
The ultra-high-pressure pump behind the fleet — proprietary core components built for continuous heavy-duty operation, with dynamic pressure adjustment across 50–300 MPa.
- Treatment Carrier H Series
The world’s first intelligent full-vessel painting platform — up to 34 m working height and 1,500 m²/h application rate, with adaptive hull tracking and closed-loop VOC treatment.
AI-DRIVEN SURFACE PREPARATION
Hydwin’s magnetic treatment carriers climb ship hulls and steel structures autonomously, removing coatings and rust at up to 3,000 bar while water and debris are recovered directly. One-man, 24/7 operation replaces scaffolding, lifts and manual crews — faster, safer and to WJ-2 / Wa 2½ surface standards.

- Ship hull surface preparation
Proper surface preparation is crucial in the marine and shipbuilding industry.
Many coating failures result from inadequate cleaning. Ensuring a clean and well-prepared hull surface is essential for the coating’s durability and effective corrosion protection in ship construction, maintenance and repair.

- Comparative analysis
Ship hull cleaning methods compared

| Abrasive blasting | Manual hydroblasting | Wall-climbing robot | Treatment Carrier | |
|---|---|---|---|---|
| Efficiency | 6 – 8 m²/h | 15 – 30 m²/h | up to 50 m²/h | up to 50 / 120 m²/h |
| Required equipment | Scaffold, abrasive materials, blasting pot, air compressor and containment system | Scaffold, high-pressure water jet systems, hoses, UHP pump, protective gear | Robot unit, UHP pump, electronic cabinet, long cables, fall arresters and safety harnesses | All-in-one system with built-in electronic and recovery modules |
| Required labor | High labor demand for setup, operation and maintenance | Very high labor demand for manual operation and safety oversight | Moderate labor demand for setup and monitoring | Low labor demand thanks to automation and remote operation |
| Working coverage | 100% | 100% | 45% | 95% |
| Cleaning effect | Several passes needed; prepared surface is less consistent | Effective in accessible areas, struggles with complex geometries | Consistently high quality | Consistently high quality, meeting near-white metal standards (WJ-2 / Wa 2½) |
| Risk points | High dust and particulate exposure, equipment-related injuries | Respiratory issues, physical strain and accidents | Mechanical failure and falling risk due to water pressure and weak magnetic adhesion | Minimal |
| Environmental impact | Extreme air pollution | Contaminates local water bodies; large water and energy consumption | Recycling and sewage treatment facilities required | Dust-free, water-saving, 99% wastewater recovery |
