At the moment we have 5 different Control Unit models and 4 types of Transducers in our Heavy Duty Series (HDS). Standard we deliver our systems with 100 Watt transducers and 10 meter PUR transducer cables.

Systems with 50 Watt transducers (with specifically adapted electronics) can be provided on request. Standard systems are sold with water-resistant transducers. Waterproof transducers can be provided on request.

Spare plug-and-play Power Circuit Boards (PCB’s) can also be supplied.

Transducer types

Shipsonic™ has different transducer types (water resistant and waterproof) with different mounting methods (eg on curved surfaces such as piping) and different Wattages.

Optimized transducer housing

We intentionally chose a PVC housing, while this is not common in shipping. However, metal housings have too much mass compared to the mass of the transducer itself. These housings, therefore, absorb more energy, sometimes resulting in the housing cracking up. The mass of the metal housing also affects the resonant frequency of the transducer. The PVC housing of the transducer is not a way of cost-saving, but a conscious technical design choice. Within the PVC housing, the resonance element of the transducer can vibrate completely independent. With the water resistant model, the contact surface of the transducer is glued directly to the object to be protected, so no intermediate steel or artificial part of the housing gets in the way.


All Shipsonic transducer models can be obtained as either:

  • 100 Watt 28kHz (standard)
  • 50 Watt 40 kHz.

Standard Transducer

Our standard model is water resistant, with a PVC housing. It is directly glued to the object to be protected

Standard Transducer with Aluminum adapter

The standard transducer can also be installed using an adaptor. This adapter can be made-to-fit. For example, when installing on curved surfaces (bucket strainers, piping)

Waterproof Transducer with POM housing and stainless steel foot

Often, there is water standing in between ballast and/or fuel tanks. Then our waterproof model is needed. It is directly glued, so use a waterproof glue or protect the glue with a kit

Waterproof Transducer, POM housing, stainless steel foot, and installation bracket

For installation in the sea chest, directly under the tube bundle, or in any tank (ballast, diesel) to prevent algae growth in the tank


Features of our ultrasonic antifouling systems

Robust system design

Shipsonic™ has chosen for a robust, industrial approach of its systems designs. Ships are 24-7 on the move. In the engine rooms, humidity and temperatures can be very high for extended periods of time. At the high seas, you cannot call a service engineer to check on problems with one of your ship’s systems. Therefore Shipsonic™ systems are purely functional, no frills such as digital displays or wireless system monitoring. All such frivolities may look nice on a trade show, but they tend to break down, making your system vulnerable. We are not concerned with cosmetics, but with reliability.

High power (Wattage)

We are one of the few, if not the only ones, who work standard with 100 Watt transducers. This not only results in more ultrasonic energy in the object you want to protect, but the heavier transducers also have a lower frequency (28KHz + – 0.5%). It is known that the lower frequencies of the ultrasonic spectrum are more efficient.

Correct frequency

A frequency 28 KHz + – 0.5% means that each transducer has its own specific resonant frequency, which varies from the factory and also fluctuates with temperature and method of installation. Our design features a standalone software module for each transducer, running through all frequencies around 28 KHz, which enables us to ensure that each transducer is optimally powered. This means every transducer always receives pulses in its own, specific resonance frequency.

Failsafe electronics design

The Shipsonic electronics engineer has made a deliberate design effort to guarantee that the transducers in our systems can be powered continuously without excessive heat generation. The life cycle of electronics is severely shortened by excessive heat or fluctuating temperatures. Our system design ensures that all electronics always stay at least 25% below its maximum temperature specifications. All control units are equipped with 2 cooling fans, one blowing inward and one blowing outward to guarantee proper air circulation inside.

Plug and play

In the Shipsonic design, each transducer is a stand-alone module, with separate power supply, separate power circuit board (PCB) and separate software module. This means that if one transducer fails, all other transducers of the same control unit will continue to function.
In case of a short circuit, mostly due to accidents with the transducer cable, the fuse on the PCB will blow. However, often also the electronics will be damaged. But since the PCBs in the control unit are plug-and-play; replacing a PCB in the control unit requires no special knowledge and requires 5 minutes, even at the high seas!

Additional options and features

On request, Shipsonic offers adaptations to our systems, as the client wishes. Most frequently, we offer the following:

  • CANBUS connection; for system monitoring in the chief engineers quarters
  • PLC (programmable logic controller); to control a large number of transducers from one point, eg sluice gates or similar large objects
  • 50 Watt; 40 kHz transducers; especially for the offshore sector involving ROVs, which use ultrasonic frequencies too near to the frequency of our 100 Watt transducers. 50 Watt transducers are supplied with specific power circuit boards, optimized for this transducer type.
