About Pondhawk Solar Aerator

The PondHawk solar pond aerator by LINNE: Designed by science, born of necessity.

The research team measures the output of dissolved oxygen in water to study to efficacy of the PondHawk solar powered aerator

When LINNE CEO and founder Sandra Burton acquired a pond with her new property, she inherited a stagnant and noxious mess of decaying organic matter that acted as a breeding ground for mosquitoes and harmful, toxic algae. Combining her engineering background with her husband’s work on photovoltaics, they created the PondHawk Solar Aeration System.

Now that stinky, green, and mosquito-infested water is free from algae overgrowth and serves as a haven for fish, frogs, turtles and at least one blue heron.

The power of the sun and solar aeration.

PondHawk is a fully integrated, patented, solar-powered pond aeration solution that harnesses the power of the sun to deliver oxygen through subsurface diffused aeration. This release of small air bubbles below the surface of the water plays a key role in water circulation. As you can see in this video, the constant movement and flow of water keeps ponds—as well as lakes and lagoons —free of harmful algae, eliminates stratification, and improves water quality and fish habitats.

This state-of-the-art solar aerator was intentionally designed with a minimalist approach to provide a low-impact footprint and eliminate any possible errors during installation with its “plug and play” components. The entire product weighs 110 pounds and arrives fully assembled. The system includes the mounting structure and enclosure, solar panel, air compressor, a coiled, weighted airline, diffuser platform and the industrial grade diffuser, which arrives ready to connect to the airline.

Allowing for the differences in soil composition and location, the entire PondHawk solar pond aeration system can be installed in as little as three hours with as little disruption to the area as possible—similar to planting a tree! Plus, a single PondHawk solar aerator can service a body of water up to one and a half acres at a depth of up to ten feet. The scalable design also allows for up to four sub surface diffusers to be attached to a single PondHawk solar panel.

These panels are specifically calibrated to a 30-degree plane to maximize the amount of power to the air pump during the summer when the sun is positioned highest in the sky and aeration is needed most. Warmer waters are havens for harmful algae blooms.

Though situated for maximum output during the summer months, the PondHawk solar aerator is designed to operate 365 days a year without batteries, chemicals or electricity. No matter if the weather is cloudy or freezing, the PondHawk continues to work year round, delivering microbubbles of oxygen even in limited sunlight conditions to keep your pond healthy, and its habitants happy.

Chief Operating Officer
Craig Burton

Craig Burton has been an innovator of pond aeration solutions since 2009. The most recent result of his engineering efforts is PondHawk® (U.S. Pat. No. 9,290,398), a fully-integrated, solar-powered, subsurface diffused aeration system to improve water quality in ponds, lakes, and lagoons.

Craig developed PondHawk to address a need that arose—quite literally—in his own backyard. The Burton property includes a 30+ year old pond that suffered from a variety of toxic issues and algae blooms, red-tide-like odors, and little evidence of life.

Upon investigation, Craig discovered that most of the pond’s problems were related to stagnation and decomposing organic debris. He also learned that subsurface aeration was the optimal way to resolve the underlying issues. Drawing on his extensive off-grid solar experience, Craig created a solar-powered subsurface aerator that eliminates the expense and complications of batteries.

Since installing a PondHawk, the Burton’s have enjoyed an algae-free pond that hosts fish, frogs, turtles, and a blue heron!

Craig’s career has been singularly focused on solar energy since he first designed and built off-grid photovoltaic systems in southern Africa, South America, and Southeast Asia. He subsequently gained experience in manufacturing and product design, working with several technology companies including GE Energy. As GE Energy’s Marketing Product Leader, Craig worked on strategic marketing and product positioning for their on-grid residential solar appliance known as Brilliance.

Born in Brazil of American parents, Craig’s extensive Spanish and Portuguese language skills brought him to the emerging international rural power markets of South America, where he developed solar products for remote off-grid power applications.
