A diffused air de-icing system that keeps water open around boat lifts, docks, piers, and marinas all winter — protecting your dock from costly ice damage for just a few dollars a month in electricity.
Diffused air de-icing systems are an excellent choice for keeping water open during the winter around boat lifts, docks, piers, marinas, and other structures. Removing and reinstalling a dock every year can be expensive — for just a few dollars a month in electricity, this system maintains open water and protects your dock from ice damage instead. A shore-mounted compressor pushes air through tubing to self-weighted diffusers on the bottom, creating continuous water movement that keeps ice from forming. A minimum of 3 ft of water depth is needed for diffused air to be effective.
From 30 ft to 100 ft docks, with dedicated shallow-water and deep-water models.
Runs for just a few dollars a month in electricity — far less than the cost of removing and reinstalling a dock.
Protects the compressor from the elements year-round.
Linear diaphragm compressors on shallow-water kits, Stratus rocking piston compressors on deep-water kits — energy-efficient and quiet.
DM2 diffusers stay in place on the bottom without extra hardware.
Compressor covered 2–3 years depending on model; tubing and diffusers covered for 5 years across the board.
| Model | Dock Length | Water Depth | Price |

How does a de-icer work, and why do I need one for my dock?
It creates continuous water movement that prevents ice from forming, keeping a portion of the water open. This protects docks, boats, and pilings from ice damage while maintaining healthy oxygen levels for aquatic life.
Which size do I need for my dock?
It depends on your dock length and water depth — shallow-water kits (DKSW30/45) suit 3–6 ft depths, while deep-water kits (DKDW60/100) are built for 7 ft or deeper. Match your dock length to the closest model above.
Will this work in extremely cold temperatures?
Yes — it's designed to function efficiently in sub-zero conditions, preventing ice formation even in harsh winters.
How much does it cost to run?
Just a few dollars a month in electricity — far less than the cost of removing and reinstalling a dock each season.
How do I install it?
Mount the weather-resistant cabinet on shore, run the included tubing to the water, and position the self-weighted diffusers on the bottom near your dock — no special hardware needed to hold them in place.
What maintenance does it need?
Minimal — periodically check the compressor's intake screen, cords, and electrical connections to keep it running smoothly.
What's the warranty?
The compressor is covered for 3 years on shallow-water models (DKSW30/45) and 2 years on deep-water models (DKDW60/100). Tubing and diffusers are covered for 5 years across all models.
