Pulsar 4400
High-power ultrasound technology.

The Pulsar 4400 an eco-friendly and sustainable solution designed to control algae and cyanobacteria in large bodies of water.
Using omnidirectional ultrasonic waves, it works by resonating throughout the entire treated area, without the use of chemicals and without impacting the ecosystem.

A leading solution for large-scale sites

The 5 Key Benefits
of the Pulsar 4400

  • 360° Ultrasonic Technology
    Omnidirectional emission ensures uniform coverage of the water surface, with no untreated areas.
  • Advanced Multi-Frequency Technology
    Emits over 4,400 targeted frequencies, allowing it to adapt to different types of algae and prevent habituation.
  • Targeted double action
    Simultaneous action on filamentous algae (cellular structure) and cyanobacteria (vacuoles), for overall control of blooms.
  • Low power consumption and long battery life
    Low power consumption (approximately 50 W) and compatibility with an optional solar power supply, making it suitable for remote locations.
  • 100% eco-friendly solution
    treatment that relies exclusively on physical methods, safe for fish, aquatic plants, and humans, as well as for sensitive uses such as swimming or irrigation.

Surgical precision against algae.

Pulsar 4400 technology Pulsar 4400 on a principle of ultrasonic resonance specifically designed to target algae and cyanobacteria.
It acts selectively on their internal structures without affecting other aquatic organisms.

The mechanism of biological action

  • Targeting gas vacuoles
    The emitted ultrasound interacts with the gas vacuoles that algae and cyanobacteria use to regulate their buoyancy in the water column.
  • Altered buoyancy
    When exposed to a wide range of frequencies, these internal structures lose their functionality, preventing the algae from maintaining their position at the surface.
  • Gradual sedimentation
    Deprived of buoyancy, the algae sink to the bottom of the water body, where they undergo a natural decomposition process without a sudden release of toxins.
  • Interruption of photosynthesis
    The loss of access to light halts the photosynthetic cycle, leading to a gradual decline in algal blooms.

The first effects are usually noticeable after a few days of use.

Safety of Living Organisms

Fish, aquatic plants (irises, water lilies), and higher organisms have different resonance frequencies; they are unaffected by the emitted waves because they lack gas vesicles.
