Our History

It all started in 1968 when an inventive marina operator in Minnesota introduced the world’s first de-icer. This revolutionary product protected marina equipment from the harsh Minnesota winters and even allowed in-water boat storage. Kasco was formed to bring this new product to markets across the country.

The company grew quickly by continuing to innovate and by bringing new and improved products and equipment to the national de-icing market. By the 1980s Kasco dominated the De-icing market, a leadership position that continues to this day.

Old Kasco De-Icers

In the mid-1980’s, the Kasco engineers modified the reliable design of the de-icer to create an exceptionally effective pond and lake aerator. Fisheries and aquaculture industries quickly saw the benefits of these aerators and a loyal customer base grew. The next evolution was to add a pumping chamber to the aerators creating beautiful and effective aerating fountains. This line of aerating fountains has since expanded to include a wide range of decorative fountains that have been installed around the world.


Today, Kasco Marine is the leading designer and manufacturer of de-icers, floating decorative and aerating fountains, surface aerators, and circulators, municipal products and biologics. We continue to expand and innovate with a commitment to producing the highest quality products possible coupled with outstanding customer support.

Kasco’s growth and market leadership is a result of listening to customer needs and desires and then responding with a full-range of solutions and helpful in-field support. Kasco continually seeks input and feedback from customers and uses that information to ensure customers get the products and features they want.
