Hull Shield HD1 Controller Only – For Ultrasonic Antifouling System

Description

As part of the new HD series, the HD1 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, as compared to previous versions.

The HD1 controller provides a dedicated signal to a single transducer which can be installed to protect hulls, drives, rudders, stabilizers, and more. This single transducer system can be combined with other systems to provide broad protection for vessels of any size. The HD1 facilitates an easier installation process compared to larger controllers when installing a transducer in an area where routing signal cables back to a larger central controller is impractical.

Please note that ultrasonic antifouling technology is designed to work in conjunction with a soft ablative bottom paint.

HD1 Controller Module

The compact HD1 controller is designed to be a low-power device that can be easily installed inline with a single transducer. HD1 controllers generate the ultrasonic signals which power the transducer and consume about 0.25Ah of current at maximum potential (when the battery system voltage is at or above 12.7V). The controller is to be mounted in an accessible location near a sufficient 12V battery system supply. The transducer signal cables are routed back to the controller.

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

Solar / Wind / Low-Power Mode

The HD1 actively monitors system voltage levels, which allows it to automatically enter a power conservation mode that is beneficial for use with solar & wind power supplies. The LOW-POWER mode is a completely automated process and reduces overall system current consumption to less than 0.125Ah at peak output. LOW-POWER mode can then adjust power consumption to as low 0.075Ah of current depending on available battery power.

SLEEP MODE

This system features an automated sleep mode where the entire system will automatically shut down to conserve system battery levels for important tasks such as motor starting and bilge pumps. The SLEEP MODE is activated when the HD1 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 (just a few micro-amps). The HD1 will automatically awaken when battery levels have returned to operational levels.

Coverage

DRIVES & RUNNING GEAR –  one transducer can provide dedicated protection for any single isolated part. Examples of isolated parts are drive shaft & props, rudders, exterior engine brackets, struts, swim platforms, and trim tabs. Because these parts are isolated from the hull and each other, a transducer is required for each isolated part.

EXAMPLE 1: Boat with Two IPS Pods – Two transducers are required; one on each pod.

EXAMPLE 2: Boat with Two Inboards – Four transducers are required; one for each engine drive, and one for each rudder.

EXAMPLE 3: Boat with Two I/O Drives – Four transducers are required; one for each engine drive, and one for each exterior cowling and bracket.

HULLS – each transducer provides approximately 200sqft of protected underwater surface area. A rough estimate of your underwater surface area can be calculated by doubling your draft, adding it to your beam, then multiplying by your LWL (length at water line).

The calculation will be: ((DRAFT * 2) + BEAM) * LWL

EXAMPLE for a boat with LWL of 40ft, beam of 14ft, and draft of 3ft.

• • • ((DRAFT * 2) + BEAM) * LWL
    • ((3 * 2) + 14) * 40 = 800sqft
    • 800 / 200 = 4 transducers required to protect the hull of this boat.

The HD1 Package Includes:

• 1x Hull Shield HD1 Control Module with Integrated Power Cable and 5ft of integrated Signal Cable
• 1x Printed Installation and Operation Manual

This unit can also be combined with other Hull Shield systems to extend protective range and/or antifouling intensity.
