Benefits of our Kasco de-icers:

  • Moves the warm water on the bottom that has been heated by the earth to the surface
  • Ideal to use on any dock or pier
  • Use when the water is already iced over or by the shoreline where the water is not iced over yet
  • Adjustable height and angle

Dock & Pier and Shoreline De-Icing

The most efficient way to keep a dock or pier ice-free is to position the de-icer at an angle. This pushes the water against the shoreline, causing it to fan out. This fan-shaped pattern (also called a “flair”) will increase the amount of open water around the dock or pier, as well as against the shoreline. If an ice-free shoreline is unnecessary, it’s best to mount the de-icer vertically, and use curtains to shape the desired area of open water. 

Shallow Water De-Icing

De-icing occurs when deeper, warmer water is brought to the surface and is circulated through a designated area. This process melts away existing ice and prevents new ice from forming. A shallow area can be easily de-iced by mounting the de-icer in a deeper area, and then directing the flow of warm water toward the shallow area. The constant flow of warm water toward the shallow area will keep the area free from ice.

Boat De-Icing

Preventing ice buildup around a boat is accomplished by positioning de-icer units at or near the bow and directing the flow of cycled water toward the stern. Some boats may be large enough to require multiple de-icers, and these should be placed in a pattern that follows the hull’s natural contours. This provides the most complete and effective ice-free results. It is also possible for de-icers to be mounted directly under the hull, on one or both sides. If the boat is anchored in deep water, a diffuser will help to circulate warmer water around the boat.
