Hull Shield HD100

Enjoy 24/7 anti-fouling protection with Hull Shield ultrasonic anti-fouling systems. Ultrasonic anti-fouling using the power of ultrasound to keep your hull and running gear clean and free of marine fouling.

Hull Shield technology has proven itself over and over again – providing years of reliable service for boaters, praised by happy customers the world over, and become the preferred choice for boaters wanting the absolute best anti-fouling solution available. Our systems offer a fully automatic solution that works around-the-clock to keep your boat clean so that you don’t have to.

Maintaining a clean hull dramatically increases performance, speed, and fuel efficiency. Keeping your hull clean with ultrasound also extends the life of your bottom paint. Layers of valuable paint are removed every time the hull is scrubbed or power-washed – using Hull Shield stops this destructive routine cycle. You will enjoy significantly less maintenance costs, haul-outs, and extended paint life – all while having confidence that your boat will be operating at peak performance and efficiency.

As part of the new HD series, the HD100 provides antifouling protection for hulls, drives, and other parts of a vessel that are prone to marine fouling.  The HD series offers an increased efficiency profile that is capable of delivering nearly double the power directly to the transducers when compared to prior versions. Additionally, all HD series products feature our latest hardware technology that boosts overall effectiveness by utilizing a higher frequency bandwidth. HD series products also provide more than twice as many frequencies and ultrasound bursts in targeted ranges.

The HD100 is a four transducer unit engineered as a stand-alone system which can be used to add antifouling protection to hulls, drives, rudders, stabilizers, and more. When used alone, it can provide ultrasonic antifouling protection for hulls up to 50ft in length, or a combination of 2 drives and 2 rudders when used for drives and stern gear. As with all Hull Shield products, the HD100 can be supplemented with additional systems to provide effective protection for vessels of any size.

Not just for hulls – Hull Shield can protect your drives and running gear too! Drives are isolated from the hull by motor mounts, gaskets, seals and other insulative materials that block ultrasound from passing to shafts, props, and rudders. Because of this, the drive system requires dedicated transducers to gain the most benefit from ultrasonic anti-fouling. Inboards, pods, sterndrives, and sail-drives can all be fitted with a transducer to enable full anti-fouling protection. Rudders are isolated from the hull in the same way as the drives and also require a dedicated transducer.

Ultrasonic antifouling works by using sound waves to physically repel fouling organisms away from the surface before they can permanently attach. As a bonus, the higher frequency band of ultrasound also disrupts the reproductive cycles of certain types of bio-fouling.

Hull Shield systems operate similar to a stereo and speakers. The controller sends ultrasound signals to transducers attached to the hull or running gear, the transducers receive the high-frequency signals, transforming them into ultrasonic pulses.

Each pulse creates a microscopic shockwave that runs across the hull and drive gear. These ultrasonic waves work to ablate, loosen, and repel fouling which is contacting the hull and drive surfaces. When used in conjunction with an ablative bottom paint, Hull Shield systems are the most effective and long-term antifouling solution available.

The Hull Shield HD100 controller is the brain behind the brawn. HD100 controllers generate signals for up to 4 transducers and consume about 1Ah of current at maximum potential (when the battery system voltage is at or above 12.7V). The controller is mounted in an accessible location near the 12V battery system supply. The transducer signal cables are routed back to the controller. The HD100 enclosure is IP68 and NEMA rated for waterproof installation, and all connections are IP67 rated or above.

HD series controllers operate on 12VDC battery systems. Please contact us for alternate options on 24VDC systems.

The HD100 controller is designed for optimum efficiency and ultrasound power delivery. The system is engineered to provide stable operation, even when powered from solar and wind supported power systems with fluctuating battery cycles. The controller will actively adjust the output power to match the current charge-state of the battery system – conserving power when necessary to preserve battery power and extend the length of time the system can operate.

The controller actively monitors system voltage levels which allows it to automatically enter  power conservation mode (PCM) when the system batteries are not being maintained. PCM is a completely automated process which reduces the average system power consumption to as low as 5 watts depending on available battery power.

This system features an automated sleep mode where it will automatically shut down to conserve system battery capacity for important tasks such as cranking motors and operating bilge pumps. The SLEEP MODE is activated when the HD100 detects that the battery voltage has dropped to 50% capacity (approximately 12.1V). When SLEEP MODE is activated, the Hull Shield halts all ultrasonic output and powers down; power consumption drops to near zero. The HD100 will automatically awaken when battery levels have returned to operational levels.

Hull Shield systems are simple in function and installation. Systems can be installed in a single day and require no technical skills. Besides the simple tools most customers have, everything required for an installation is included in with our products.

The Hull Shield controllers are best mounted in an accessible compartment. The transducers are simply attached directly to the surface of the hull or drive with the supplied 2-part epoxy.

Hull Shield transducers are waterproof and submersible. Transducers can be attached to the inside surface of the bilge, or externally on the transom.
