Kasco 4400D Series 1HP - Energy Efficient #1 Selling Deicer Brand

Designed to combat the harsh elements, the Kasco 4400D Series deicer employs a 1 horsepower motor, generating an unparalleled 42 lbs of thrust to:

  • Prevent Ice Formation in Target Areas
  • Protect in Water Property from Ice Jacking
  • Promote Essential Oxygen to Enter Water
  • Prevent Winter Fish Kill 

Why do I need a deicer? 

During winter there is a temperature drop, water at the surface cools and can eventually freeze. In colder regions ponds may freeze partially or completely creating ice formation around docks, boats, pilings and other in-water structures. When ice forms it expands and can cause extensive damage to your in water property. If you are looking for an effective ice eater, installing a de icer will aid in preventing ice formation in the target areas. 

How does a dock deicer work?

When a deicer is activated it creates movement in the water, bringing the warmer water up to the surface. By keeping the water in motion, the deicer prevents the surface water from reaching freezing temperature, hindering the formation of ice. This opening helps protect your property in the water from damage caused by ice and potential ice jacking.

Are there other benefits to installing a deicer? 

Creating an open surface area in the ice allows essential oxygen to enter the water. This is particularly important for supporting aquatic life during winter when oxygen levels may otherwise become limited, the use of a deicer can help mitigate the risk of a winter fish kills.

How to install a dock bubbler/deicer:

To effectively circulate warmer water from the bottom, the deicer unit must be installed a minimum of 4 to 6 feet below the water surface and at least 1 ft off the bottom. Kasco offers two basic instillation options, rope suspension, or dock mounting. Different de-icing objectives require different mounting approaches, you will need to decide which mounting option is best for you. Vertical instillation creates a circular shaped opening  and angled installation creates an oblong shaped opening at the surface of the ice.
