The Quattro-DB Ultrasound System includes the sonic head, power module, float, and 10 meter power cable. The water-proof power cable is required and can be customized for lengths up to 500 meters (contact us if you require an extended cable). Select the best length above to suit your application.
The Quattro-DB can be used in ponds and lakes as large as 120 acres (or more with multiple units), depending on the algae type that you're dealing with. For thicker, filamentous type algae, around 17 acres of coverage could be expected. Less dense single-cell algae allows for greater range of coverage.
The Quattro-DB is omni-directional, which provides 360 degrees of coverage from the device and it uses dual bandwidths for greater frequency density. These are both
features not found before in ultrasonic
devices. The omni-directional sound output is
achieved with just one piezo sound emitter that
operates in two different bandwidths for better
control of green algae and diatoms in the lower
bandwidth and blue-green algae in the higher
The device works in harmony with aquatic wildlife
(fish and animals), aquatic plants, bio-solids and
planktonic organisms other than algae. Since
the device can control biofilm formation on
cleaned surfaces, you may notice surfaces near
the device remain clean for long periods after
being initially cleaned. This is due to inhibiting
anaerobic bacterial colonization due to their
sensing the ultrasonic signature as water turbulence. Fungi (e.g. Pythium) and bacteria with gas
vesicles will also be controlled by the device by
causing them to lose buoyancy.
The device creates ultrasonic frequencies that
cover two important bandwidth areas where
algae can be controlled via critical structural
resonance similar to the way a crystal glass can
be broken by the right sound pitch. Ultrasound
works as the force to cause these internal
vibrations in algae cells or in organelles inside
the algae cells that disable them. The system is
powered via the power module that is available
for use with many types of power input including solar.

Peak instantaneous power - 50 watts.
The Quattro-DB Ultrasonic System is made up of three main components. These are the ultrasonic head, the power module/controller, and the power cable. A float and attachments are also included.
This contains the frequency driver and the sonic emitters
that produce the ultrasonic output signal. The top and bottom sections
house the piezo sonic emitters. They are offset by 90 degrees so that the sound
is projected radially away in 4 directions. The two way output and the
two piezo mounts are unique in the industry.
This can be AC or DC electrical input. AC inputs include
24, 100/120 and 240 volt service at 50 or 60 Hz. DC input is 24 volts via
solar or AC charged batteries (typically two 12 volt batteries in series.)
The power module converts the input power to the 40 volt DC line
voltage needed to power the sonic head.
This connects the power module with the sonic head.
This provides power and communications to and from the sonic head.
The standard cable length is 150 meters (about 500 feet) but lengths up
to 500 meters (about 1640 feet) are possible. Other devices of this type
are typically limited to cables lengths of 75 meters due to cable voltage
drop reduces the driving voltage for the circuit and the sound output
level drops proportionately. The *Quattro-DBTM has compensating
circuitry in the sonic head that boosts the incoming voltage to the 40
volts needed by the circuitry and is a unique and patent pending feature
of the device.
This provides buoyancy for the sonic head and cable. The
placement of the device is normally away from the bank so that there is a
line of sight from the device to as much of the shoreline as possible. A
flag on the float warns boaters not to anchor there due to the cable
below. The user supplies an anchor to which the unit is tethered. The
cable runs back to shore to a power supply run on AC or DC power.
