Protecting Your Dock From Ice

Protecting Your Dock From Ice

Harsh winter conditions can lead to expensive damage around docks. Ice jacking, floating ice, and ice expansion are all threats to protect your dock against.

The proactive solution is a dock de-icer. There are two different options for keeping ice away from your dock. Kasco De-Icer is a dock suspended motor that moves large volumes of water. The movement of water creates an opening of approximately 50 ft (with Kasco 2400D). The second option for ice prevention is the Natural Waterscapes Pond Aerator. This system is comprised of an air compressor, weighted airline and diffuser. The compressor, which sits on the dock or shoreline, pushes air through the diffusers creating columns of fine oxygen bubbles. The movement of water created by the diffuser that sits at the lake bottom keeps a similar protective opening around the dock. 

Although each style of de-icer effectively clears ice, there are some significant differences in their operation. 

Kasco De-Icer 2400D:

  • Water Pump That Sits In Water Under Dock
  • Moves 500 Gallons Per Minute
  • Minimum Operating Depth of 4-5 Feet Below Water Surface
  • Ideal For Docks Installed in Deep Water
  • 5 Running Amps (1/2HP Motor)

Natural Waterscapes Pond Aerator System / Dock De-Icer:

  • Air Compressor That Sits On Dock or Shoreline
  • Pushes Air Through Diffuser(s) That Sit Under Dock on Lake Floor
  • Moves 2100 Gallons Per Minute
  • Operating Depth Of 3-12 Feet
  • Ideal For Docks Installed in 12 Feet or Less
  • 1.6 Running Amps (1/4HP Motor)
  • Breaks Down Muck Around Dock!

When is the best time to install a dock deicer?

In Northern climates, ice can begin forming as early as November. Although major formation may not begin until December, we recommend installation in October to November before the weather takes a turn. Optional thermostatic control available to turn on deicer once water reaches 39 degrees.

How do De-Icers keep water from freezing?

Submersible motors like the Kasco De-Icer pulls warm water up from the depths of the pond to the surface. The recirculation of the deeper, warmer water keeps ice from forming. 

For water shallower than 6 feet, a bubbler/aerator system is ideal. This style pushes large volumes of oxygen into water, creating enough friction to keep water from freezing.
