HDX
COMMERCIAL
SERIES
Stop the fouling, lower your costs, and save time, all while increasing efficiency and performance.
Industrial-grade ultrasonic antifouling for vessels that cannot afford down time.
The Hull Shield® HDX Series uses industrial-grade ultrasonic energy to prevent biofouling on hulls, propellers, shafts, pod drives, jet drives, steering and control gear, sea chests, box coolers, pipework, keel coolers, heat exchangers, RSW cooling systems, and bulk storage tanks — without coatings, chemicals, or mechanical intervention.
Operating continuously 24/7, HDX systems help commercial and industrial operators reduce fuel consumption and emissions, improve vessel performance and handling, extend service intervals, and protect long-term asset value – even in the most aggressive fouling environments.

HULL SHIELD® HDX SERIES
The Hull Shield® HDX Series represents the highest level of ultrasonic antifouling technology engineered for commercial vessels, workboats, offshore assets, and industrial marine systems.
Designed to operate continuously in the most demanding marine environments, HDX systems deliver exceptional ultrasonic power transfer, high-depth resonance transmission, and unmatched durability. The result is reliable, long-term protection of high-value marine assets – reducing operating costs, minimizing downtime, and preserving system performance.
Hull Shield HDX systems operate 24/7, preventing biofouling from establishing on protected surfaces without additional chemicals, coatings, or mechanical intervention – making HDX an ideal solution for operators focused on efficiency, sustainability, and asset longevity.
INDUSTRIAL-GRADE PERFORMANCE
Hull Shield® HDX systems are engineered to deliver the highest unit transfer of ultrasonic energy available, providing superior range and transmission across large structures and dense materials.
Key performance characteristics include:
- Continuous-duty ultrasonic output engineered for industrial operation
- High-depth ultrasound transmission through thick hulls, heavy steel components, and complex systems
- Scalable system architecture supporting large vessels and multi-zone installations
- Proven reliability in harsh, high-load marine environments
HDX systems are designed not only to prevent fouling, but to support mission-critical reliability, where vessel uptime and system performance directly impact operational cost and safety.
PROTECTING YOUR ASSETS
Reducing downtime, maintenance burden, and operational risk is critical when assets are working continuously and revenue is on the line. The Hull Shield® HDX Series provides a powerful, non-intrusive layer of protection that safeguards critical underwater and seawater-system components while supporting long-term asset preservation.
Operating continuously, HDX ultrasonic antifouling systems actively prevent biofouling from developing on protected surfaces – without toxic chemicals or invasive installation methods.
Hulls
Large commercial hulls are protected using a distributed array of industrial ultrasonic transducers, providing broad, consistent coverage that helps maintain hydrodynamic efficiency and reduce drag-related fuel consumption.
Shafts & Props
Ultrasonic energy can be transmitted directly through the shaft, protecting both the shaft and propeller simultaneously while maintaining smooth, efficient propulsion.
Pod-Drives
When pods become fouled, both thrust and steerage are affected. Fouling leads to poor fuel efficiency and reduced handling response. Z-Drive and L-Drive pods can be targeted directly with Hull Shield ultrasonic antifouling.
Jet-Drives
Performance and efficiency can suffer significantly from fouling inside the drive. Fouling remediation can be complicated and increase downtime. Hull Shield can target jet-drives to reduce fouling and maintenance.
Steering & Control Gear
Hull Shield ultrasound can be used to target steering, stabilizing, and other control surfaces. Reducing fouling on these surfaces increases hydrodynamic efficiency and results in more responsive and safer handling of the vessel.
Sea Chests & Box Coolers
Invasive biofouling in sea chests and box coolers reduces cooling capacity and increases maintenance downtime. If left uncheck, fouling within the cooling system can lead to equipment failure. Ultrasonic antifouling can be easily deployed to protect these areas using non-intrusive installation methods.
Pipework & Valves
Biofouling can affect the flow rate and function of various types of pipework. Targeted ultrasound treatment is effective at reducing fouling in pipes and decreasing subsequent maintenance intervals and downtime.
Keel Coolers
Keel coolers have constant exposure to raw seawater. Bio-fouling accumulation on the cooling elements leads to reduced cooling capacity and downtime. Hull Shield ultrasonic transducers can specifically target these exterior components.
Heat Exchangers & RSW Cooling
All inboard open circuit systems are prone to damage caused by fouling accumulation and require routine maintenance. Ultrasound can be deployed to mitigate biofouling and increase system efficiency.
Diesel & Water Tank Storage
Diesel fuel and water storage tanks are susceptible to the dangerous and damaging effects of fouling and bacteria. Ultrasound is effective at mitigating the consequences of bacteria and microbe accumulation in these reservoirs.
