The Dock Mount De-Icer creates continuous upward water circulation to protect docks, boats, pilings, marinas, boathouses, and waterfront structures from damaging ice. The system draws warmer water from beneath the surface and directs it into the surrounding area.
The ½ HP 230V configuration moves approximately 400 gallons of water per minute and provides a water-flow distance of 50 feet. During extreme below-zero conditions, this motor size is designed to keep a minimum 50-foot-diameter area free from ice.
Its fully submersible motor is oil-free and built for continuous winter operation. The adjustable stainless-steel yoke provides up to 7 feet of depth adjustment
