The high-performance motor in the 3400D de-icer creates large amounts of water flow that will prevent ice formation and protect property from the damages of ice jacking and ice expansion pressure. The unit will also allow oxygen to enter the water in the winter providing improved water quality and habitat and helping avoid devastating winterkill of fish. A single 3400D unit can keep a circle of water open up to 75 ft. in diameter.

The 3400D is available in 120V (60Hz), 240V (60Hz) or 220V (50Hz) power configurations.

All units come with two 20 ft. (6m) mooring lines; optional mounting systems including a universal dock/pier mount, industrial dock/pier mount, or a horizontal float are available. Thermostat and timer controllers are also available to help you save power and improve your de-icer’s performance.

  • High-efficiency design means low power compensation and low operating costs
  • Heavy-duty motor and corrosion resistant design; suitable for salt-water or other corrosive environments
  • Safety Tested: ETL listed to UL and CSA Standards, 50Hz model is CE marked
  • An easily replaced protective sacrificial zinc anode included with each unit
  • Low maintenance and dependable design
  • Backed by a two-year warranty
  • Ships via UPS
  • Multiple cord lengths available (see charts below); all SJTOW underwater rated (50 Hz models are available only with 10M or stub power cords)

Sizing Chart

The table below will help you decide which de-icer unit will work best for you. Choose which temperature best describes your application and which mounting orientation you will use. Based on those decisions, you will then see how much water will be kept open with each unit size.

Sizes may vary greatly based on a number of local conditions. The above sizing guidelines are made with the following assumptions:

  • Unobstructed water
  • 200 or more acre body of water with 20 ft. (6 m.) or greater max depth
  • Water depth in de-icing area: 4 ft. (1.2 m.) or more
