HullSonic MAX2 Ultrasonic Antifouling System — 2 Transducers, Superyacht Duty (Formerly CleanAHull)

Our industrial platform, built for superyachts. Higher output, channel grouping, and the integration I/O a managed vessel actually needs.

MAX2 is a full four-channel commercial-duty control module supplied with two transducers — and the same upgrade path to four.

Where MAX comes from

MAX is the recreational-facing edge of the industrial ultrasonic work GLOBAtech has been doing for two decades — heat exchanger cleaning, sea chest protection, commercial fleet installations. Those systems run continuously, on vessels where a fault that goes unnoticed costs real money. What came back from that program is what MAX is: more output, more control, and the ability to talk to the rest of the boat.

Formerly CleanAHull, now consolidated into the HullSonic range under the MAX name. Same architecture, same engineering lineage, one brand.

45–65W per channel, defaulting to 60W

Where the HS series runs 45–55W, MAX runs 45–65W per channel, factory-set to 60W — more acoustic energy into the hull, with more headroom when fouling pressure demands it. On thick steel or aluminium hulls, cored sections, and vessels in persistently warm water, that margin is the difference between control and catch-up.

Channel grouping

MAX can operate two matched channels as a bonded pair, driving a matched transducer set together across a single acoustic zone. On large flat hull sections, sea chests and box coolers — where a single transducer can't load the structure evenly — grouping delivers coherent coverage instead of two independent sources fighting for the same panel.

Integration I/O — the part that matters on a managed vessel

• Alarm header — fault and status output to the vessel's monitoring or alarm system, so a failed channel raises a flag at the panel instead of being discovered at haul-out.
• Isolation input — clean external inhibit for hot-work, diving operations, survey or any procedure requiring the system stood down, without pulling breakers.
• External boost input — trigger BOOST mode from a vessel management system, a timer or a switch, for scheduled high-output periods.

This is the specification difference between a recreational product and one that belongs in an engine room with a documented systems list.

Four channels of hardware, two working today

Like every current HullSonic module, MAX2 is four-channel hardware with channels 3 and 4 inactive. The HS-T50 Transducer Upgrade Kit takes it to a full four-transducer MAX4 installation whenever you're ready — no module change.

Colour display, WiFi and OTA

Full-colour per-channel status, drive power, calibration state and fault reporting. WiFi for configuration, diagnostics and over-the-air firmware updates.

12–24VDC auto-sensing

Specifications

What's in the box

• 1 × HullSonic MAX2 Control Module (4-channel hardware, 2 channels active)
• 2 × HS-T50 Ultrasonic Transducers, each with 32ft (10m) silicone cable
• 2 × HullSonic transducer mounting footprints
• 1 × Tube Loctite 515 transducer gasket material
• 1 × 16ft (5m) silicone rubber battery power cable, pre-attached to the module
• 1 × Transducer installation kit (JB Weld epoxy adhesive and mixer)
• 1 × In-line fuse and spare fuse kit
• 1 × Full-colour installation and operation manual

Please Note: HullSonic ultrasonic anti-fouling systems are provided with 32ft of cable per transducer. Depending on boat size, you may require additional transducer cable to reach the transducer mounting location. Typically this can be extended using the off-cuts from other transducers installed closer to the control module, or using the same type of cable. Contact Us for assistance with extension advise. Lengths can be extended up to 60m.  This unit can also be combined with other HullSonic systems to extend protective range and/or anti-fouling intensity.
