Mounting Options

Rope Suspension

Kasco De-Icers come complete for suspended operation from a dock or boat in either a vertical or angled position. The angled operation by suspended method or with optional flotation unit produces an elongated pattern of agitated water. A vertical positioning produces a circular pattern. Vertical positioning of the De-Icer works well under boats and docks or between slips and boats.

Universal Dock Mount

Kasco Marine, Inc. offers an optional Universal Dock Mount or piling mount that can be used with any Kasco De-Icer. This heavy-duty Universal Dock Mount or piling mount is made from corrosion protected steel and stainless steel to withstand the toughest marine conditions. The De-Icer is mounted to the "underwater parts" of the Universal Dock Mount and the "above water" parts are mounted to the dock or piling. Due to shipping limitations, a 1" pipe extension needs to be supplied by the purchaser to connect the "underwater parts" and "above water" parts.

Horizontal Flotation Unit

Kasco Marine, Inc. offers an exclusive, arctic proven flotation kit that is optional for all De-Icers. The easy-to-assemble kit consists of stainless steel components and a flotation block. The De-Icer unit is mounted horizontally to the surface of the water, just below the flotation block. The De-Icer can be angled in several positions; horizontal and above and below horizontal.

The horizontal operation of the De-Icer produces an elongated pattern of agitated water. This is well suited for tough problems such as shallow water areas, areas where water and ice levels fluctuate such as tidal waters, or where elongated open water areas are desired, such as around long docks. With adjustable angles above and below horizontal, the De-Icer can also be suited to fit many water depth and obstruction conditions.

De-Icing Facts and Factors


  • 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 De-Icers largely depends on the depth of the surrounding water, obstructions in the water, and the geographic location of the installation.
  • All De-Icers work by moving warm bottom water that is heated by the earth to the surface. The shallower the water in the area surrounding the De-Icer, the less warm water there is available. It is recommended that the De-Icer is 2.5' to 5' below the water surface.
  • Obstructions in the water such as floats on docks, boat lifts, large dock pilings, boats, etc. may restrict the flow of water causing a smaller area of influence around the De-Icer.
  • Your geographic location will also play a major role in the effectiveness of your Kasco De-Icer. The longer and colder the winter is, the more the water will cool over time and open water may be limited accordingly.
  • Other factors that may effect open water areas are bottom contour, salt content, mounting, etc.

*Typical open area describes an upper estimate of area that will be cleared. Even in the coldest climates these units should at least perform at 50% of this estimate.

Below are some common ice damage problems, as well as winter-kill conditions and summer water quality problems. De-Icers can help in each instance.

Utilizing your Kasco De-Icing Equipment

To De-ice a shallow water area, direct the flow of warmer water from the deeper area into the shallower area. Remember, a De-Icer works because it draws warmer, denser water from the bottom and circulates it upward to the surface, preventing ice formation or melting existing ice.

It is often easier to De-ice a boat by installing the de-icer at or near the bow, angled toward the stern. If the water flow is directed toward the shore or a retaining wall, it will flair, forming a desirable"T" shape de-icing pattern.

In tidal waters, split the difference in water depth so the De-Icer is in shallow water at low tide and deep water at high tide. Or, tie your De-Icer to the boat and allow the boat and De-Icer to rise and fall with the tide.

Ice Jacking / Lifting damage

Keep Your Marine Facility Like This.....

.....and avoid the situations shown below

Jacking / Lifting damage can occur anytime ice and water levels fluctuate. The most common cause of lifting is the tide; however, lifting damage is common in the Great Lakes Region where weather and wind changes can cause smaller, but more rapid changes than tides. Jacking damage can also occur on any body of water regulated by man.

Repair costs are not only limited to physical damage, but also to the down-time of dock facilities and time spent obtaining necessary government permits.

Maintaining an ice-free zone in and around dock structures is your very best protection against jacking / lifting damage. Keeping partially open water near dock structures will reduce ice thickness in the general area around docks and pilings and help to limit the risk of ice damage.

Ice Expansion Damage

Ice expansion pressure is a vastly underrated damage risk. The size of a body of water is directly proportional to expansion damage risk potential. The larger the body of water, the larger the potential damage risk will be. Pressure damage can affect that part of the dock structure nearest the shore or at the opposite end as shown above.

Although it may be preferred to maintain an ice-free zone around the dock structure, it is also possible to limit damage risk with an open water buffer zone. Kasco Horizontal Flotation units positioned between docks and expanding ice can relieve damaging expansion pressure.

Winter Kill Conditions

Kasco De-Icers can be used to help prevent winter-kill conditions. During harsh winters with thick ice and heavy snow pack, your pond can experience a fish die off due to low oxygen levels. The heavy snow and ice prevent sunlight from penetrating into the water causing the existing aquatic vegetation to die off. As the vegetation dies, the decomposition process uses up much of the available oxygen in the pond. As the winter progresses, the oxygen levels continue to decrease and eventually, your fish may begin to die. Only 1% of the ponds total surface area needs to be ice free to prevent winter-kill situations. The cold water will become oxygenated by coming in contact with the air and prevent winter-kill on your pond.

Summer Water Quality Problems

Water quality during hot summer weather is an increasing problem for marinas and waterfront developments. Sheltered water, behind docks or under walkways where wind and current cannot reach, tends to become stagnant and dirty. As a result, algae and odor problems often develop, destroying an otherwise pleasant outdoor experience.

The use of Kasco De-Icers during hot summer weather to create a man-made current helps "Mother Nature" with her natural cleaning action. The quiet-running Kasco Horizontal Flotation unit produces an aesthetically pleasing high-volume water current in marinas, waterfront developments, and park facilities for improved water quality.
