FAQs

No. In fact, not at all!

The NOXX HYD™ antifouling system was designed to stop marine fouling on vessels without causing harm to marine life. The system uses a low frequency pulse in the range of 27 Hz that deters biofouling organisms such as mussels and barnacles from attaching to surfaces exposed to seawater. In contrast, ultrasound uses much higher frequencies from 20kHz or more to prevent biofouling organisms from attaching.

Unlike ultrasound, low frequency pulses used by NOXX HYD™ do not harm the food source or marine life larvae.

No.

The NOXX HYD™ system does not remove weeds, grasses, or slime. This is on purpose. The goal of the system was to solve fouling problems without harming any of the ocean ecosystem. Weeds and grasses can easily be removed by spray washing and, in internal piping systems, the flow rate will wash away a lot of the plant life. Since there is no hard fouling present, it is also the case that grasses have very little grip on the surfaces being protected.

Absolutely not. Unlike ultrasound, the NOXX HYD system does not create cavitation. Studies have shown that cavitation damages welds and gradually eats away the steel surfaces being protected. NOXX HYD will not damage the vessel it protects.

Don’t take our word for it, Google the effects of cavitation on metal.

The NOXX HYD™ system will work from as little as a 120 or 220 volts AC as well as 12 or 24 volts DC system and output 12 volts DC[1] with minimal energy consumption. Each emitter draws 0.1 amps at 12 volts DC during operation.

This is great for energy savings.

Each emitter only draws 0.1 amps!

Yes.

To continue to deter the larvae it is advantageous to have the NOXX HYD™ system protecting your vessel 24 hours a day. A crustacean larvae takes two weeks to become fully attached, therefore it is possible to have the system off for up to a week because the minute the system is turned back on, the week-old larvae will leave the area immediately. This however is not our recommendation.

Yes, but it is not recommended.

Yes.

The emitters are attached to the inboard side of the vessel, and the control panel is placed above-deck or below-deck in the engine room.

The NOXX HYD™ antifouling emitters are built using the latest digital technology and are mounted inboard. All of the fittings, emitters and cabling are built to withstand the harsh marine environment. They are IP66 rated which means they can be splashed etc., but not submerged. Many installations of NOXX HYD™ systems have had a track record of lasting at least 10 years.

The NOXX HYD™ system is designed to withstand the marine environment and has been designed, developed and assembled using IP66 components. The NOXX HYD™ has been in the industrial marine industry since the 80s and, in some cases, has shown a track record of being effective for 10+ years without requiring maintenance. We are confident in our product and an extended warranty is available on request for up to 5 years on the emitters and 1 year on the control panel from the date of purchase. Should a problem arise, please contact us directly at 250-656-5366.

Depending on your hearing ability, you may hear a faint clicking sound at the emitter. The majority of the low level sound is inaudible above any other normal sound produced on a vessel.

No.

One of the greatest qualities outside of its ability to prevent marine fouling is that the NOXX HYD™ requires almost no maintenance!
