Ice build-up in winter can cause lots of problems for boats, dock pilings, and boathouses as well as for fish and wildlife ponds. The Scott Aerator Company focused its 45 years of experience to develop superior de-icers that are efficient, reliable and extremely durable in keeping surface areas free of damaging ice.

A heavy-duty, stainless steel dock plate, pipe, and yoke assembly suspend the Scott Aerator Dock Mount De-Icer under the water’s surface. It mounts quickly and easily to almost any type of dock, and can easily be adjusted to accommodate different water levels. The Dock Mount De-Icer keeps ice from forming by bringing warmer water from the bottom and sending it out in a continuous agitated movement. This helps prevent dock pilings from being jacked, or lifted, by acting as a buffer to prevent ice expansion and pressure damage. Under extreme, below zero winter conditions, our 1/2HP De-Icer will keep a minimum 50 foot diameter area ice free, and up to 70 feet using the 1HP model.

DOCK PLATE (INCLUDED)

Perfect for long-term installation to a dock or similar structure.

DOCK POST BRACKET (UPGRADE)

An excellent mounting option for docks with round, metal posts. Upgrading to the dock post bracket replaces the standard dock plate.

TRUSS MOUNT (UPGRADE)

Works well on metal docks and comparable frames using a sturdy, non-destructive attachment method. Upgrading to the truss mount replaces the standard dock plate.

FREE-STANDING POST (UPGRADE)

Where permanent structure is not available, the free-standing-post upgrade offers excellent flexibility for placement. Upgrading to free-standing post replaces the standard dock plate. Includes a sturdy, 8-foot post and the dock post bracket. 

The De-icer safely mounts to your dock via the included stainless steel mounting plate, or you can add a post-mounting bracket at additional cost. The stainless steel yoke assembly the unit is attached to reaches a depth of up to 7 feet. You can select an alternative mounting option using the menu above when you add it to your cart (best value), or you can add a second, additional mounting option by purchasing a second mount.

Our fully programmable oscillator attachment helps keep larger areas free from ice build-up without the need to purchase a second de-icer. The oscillator turns the de-icer in its mounting. It's pre-programmed to rotate in 20-degree increments every 20 minutes. You set it for any radius you wish. Then plug it in and forget about it! The oscillator attachment can be added at purchase or later after installation.

Compare to similar products and you’ll see why the Scott Aerator Dock Mount De-Icer far surpasses anything else on the market. Here are some of the differences:

• Our De-Icer is engineered for all water temperatures.
• The De-Icer runs at 3450 rpm. Competitive de-icers, even those with 1-hp motors, run at fewer than 2000 rpm. This means the Scott De-Icer moves 400 gallons per minute compared to the competitors' 180 gallons per minute.
• The De-Icer is manufactured using American-made stainless steel, even the motor. The competition utilizes galvanized metal.
• The De-Icer comes standard with an unconditional, 5-year motor warranty. Competitve models warrant their de-icers for just two years.
• GFCI required. Please disconnect power when swimmers are present. Greater cord lengths are available.
