De-icers push warm bottom water up to the surface creating an ice-free area of protection around your boat, dock, or pier. Kasco De-icers create more thrust than any other competitor, meaning more open water to better protect your property.

Kasco De-icers are designed and engineered for continuous duty in the harshest environments. In addition to protecting your in-water properties, these units help keep fish and aquatic species healthy throughout the winter by allowing for open areas where oxygen can enter the water. De-icers are lightweight, energy efficient, and easy to install and operate.
