Kasco De-icers are perfect for preventing costly ice damage due to jacking/lifting, ice expansion, and winter-kill conditions. Kasco De-Icers are industrial strength and designed and engineered to withstand the harshest marine environments making Kasco THE LEADER IN ICE CONTROL ENGINEERING! Kasco Marine, Inc. offers several sizes, models, and mounting options of De-Icers to accommodate almost every application and condition. With sizes of 1/2, 3/4, and 1hp and units available in 120V or 240V, Kasco De-Icers easily fit your location and electrical requirements. Kasco De-Icers can be suspended by ropes, mounted on an optional Universal Dock Mount, or attached to an optional Horizontal Float for operation in many conditions.

Also, optional De-Icer Controllers (C-10 and C-20) can be added to the De-Icing system to help control electric bills.

De-Icing is accurately referred to as an art form more than an exact science. Each application and location is different and there is no set rule in determining how many De-Icers are needed for a given area or which mounting option is the best. The effectiveness of your Kasco De-Icer depends on many factors. Keep in mind the following table is to be used as a general guideline and each situation is different. Please contact us to assist in sizing and location if needed.
