Dock Bubbler Packages

What you need for a bubbler de-icer for a dock, boathouse or marina. A step by step guide for setting up your dock bubbler
Please contact us by email for information or commercial deicing projects.


Step 1: Install the compressor in your boathous or shed. Build a simple wooden box if you don't have a nearby shelter handy.
Step 2: Connect the weighted airline to the valve outlet that is supplied with the compressor. Tighten clamps firmly but do not overtighten.
Step 3: Connect the weighted self-sinking airline to the bubbler tubing. Do not bend it sharply as it can kink. The lead keel can be cut with metal shears. Make sure the end of the bubbler tubing has a plug on the end!
Step 4 : Start the compressor. Having airflow running through the line during submersion helps ensure your placement is correct as you can follow the bubbles at the surface and ensure the water movement is uniform.
Step 5: Install the diffuser de-icer line around the area you want to keep free from ice. Usually the tubing, which is weighted, is placed on the outside edge of the structure you are trying to protect. The tubing should be kept on a fairly consistant depth or you will lose bubbles in deeper zones. The tubing can also be attached to the pilings of the dock or fixed to suspended
stakes which are attached to the dock to ensure the tubing is at a consistant depth.
Step 6: You're done..there is no Step 6!

** Bubblers are for dock areas less than 6 feet deep usually and deicers and thrusting agitators are for dock and marina areas that have more than 6 feet of depth.More deicer information

The principle of a keeping a dock or marina clear of ice is to ensure that the natural crushing pressure of ice is not able to squeeze the structure. Ice is so powerful that it can literally lift lake bed pilings out of their footings and toss them about like sticks. I have seen large yachts tied up in large Eastern Seaboard marinas suffer thousands of dollars of damage due to ice. The sad part is that almost all cases of ice damage and dock damage are a result of negligence by eh owner or sheer laziness; installing a homemade dock deicer or dock bubbler is not really difficult but the key is to start preparing components and supplies early enough in the season, October or November, to not get caught without a viable system when the cold snap first falls and often surprises!

While ice usually forms in shallow or areas in lakes and ponds without circulation it is important to remember that early ice formations can occur in November in some areas. While typical ice thickness will not maintain a constant spread until December in most Northern Latitudes the freezing of ponds can occur without warning so it is better to buy an inexpensive dock bubbler or build a dock deicer before it is in January and the ice is thicker than you'd like!

Types of deicers, ice eaters and dock bubblers
We usually help three different kind of people with building their bubbler;

1 - People with a small boat slip or boathouse they want to keep ice free so they can leave everything in place and not hail their boat out every winter,

2 - People who have larger docks our breakwaters out into a bay, lake or pond, either freshwater or saltwater, who need to keep large areas free of ice.

3 - Marina owners who need to keep multiple slips and dock pilings free from the pressure crush of pack ice or moving pack ice which can damage a dock or valuable boats.

For the small and medium sized applications we have built two all inclusive packages that include all the componants you need including compressor, tubing, bubbler line, clamps, connectors, caps and hardware. The small system includes 100 feet of self-sinking bubbler hose and 100 feet of weighted airline while the larger system has 250' of bubbler hose and 100 feet of self-sinking airhose.

Rotary Vane Compressor with high efficiency and energy saving build means electrical costs are at a minimum. The compressors are efficient rotary vane compressors which provide good airflow and pressure.

The larger systems are rated at 9.5 CFM at 5 PSI and 8.8 CFM at 10 PSI and are available in single and triple phase configuration. When you buy our smaller packages the pump is a 1/4 HP rotary vane pump that delivers 4.0 CFM at 5 PSI and only uses 5 AMPS. The compressors are not designed to be left outside in the snow and rain so a small shelter must be built to house the compressor, or you can use a boathouse or existing fockside shed to put your compressor.

Diffuser Tubing also called diffuser line, de-icing hose or bubbler line or De-Icer Tubing can be useful in bubbler systems and dock and boathouse bubblers when the traditional de-icers do not work due to the shallow natuer of the dock. While some people we know have had success building a bubbler line out of scehedule 40 PVC pipe with small 1/16" holes drilled every 12 inches or so this can require very large pumps and often the lines fill with water or perform only partly due to slight differences in hole size.

The tubing in this de-dock bubbler package has unique die cut slits located every 1-1/2" in groups of three which flex the airline tubing and allow air bubbles to flow and rise to the surface performing the deicing. The tubing slits close when air pressure is stopped and any water that accumulates in the bubbler tubing will be blown out of the holes upon the re-starting the compressor.

This sort of deicer works best when you have deeper waters around the dock but keep in mind that even an agitator aimed at the shallow shoreline, if it originates in waters of say 12 feet deep, can create a large opening under the entire dock structure. The size of the opening in the ice depends on the overall ambient air temperature but typically even a 1/2 HP or 3/4 HP device can open up a hole in the ice up to 60 feet in diameter.

When it is desirable to prevent ice damage in large marinas or yacht clubs over winter several units can be combined together to create a huge current that will open upon incredibly large amount of water. These units can either be suspended below the dock or pilings by nylon mooring ropes or can be attached to some sort of dock mount system. Several manufacturers, like Kasco Marine, offer high quality dock mount apparatus that allow you to strictly control the angel of attack of the deicer unit by using a graduated bracketing system.

When a dock is in shallow waters the popular deicer or ice eater may not work as well because this sort of motor needs to push warmer waters to the surface in order to be effective. When waters are 6 feet deep or less there is less temperature stratification in the water and even the water at the very bottom can be too cold to effectively melt surface ice. While the agitation of the water will keep a small hole open even when trying to deice a shallow area the diameter of the hole is typically smaller.

In shallow waters the most popular system is called a bubbler or a dock bubbler. This sort of system involves an air compressor on the dock or shore mounted that blows air into diffusers or a diffuser line like a diffuser line, de-icing hose or bubbler line or deicer tubing which is a weighted perforated tubing that releases tiny bubbles down the length of the tubing. The long linear length of bubbles creates a constant movement of water and this steady flowing curtain of bubbles ensures that there is no ice formation along the dock structure or boat slips.

Previous generations of weighted tubing were lead-lined stiff plastic PVC tubing with die cut slits ever 12 to 18 inches. I have found this tubing to be susceptible to kinks and ruptures not to mention the lead metal keel that was designed to keep the tubing on the pond bottom actually used a poisonous metal which has since fallen out of favor with anyone concerned about the potential health effects of heavy metals in our water. Newer developments in diffuser tubing have seen improvements in efficiency and safety by using all PVC diffuser tubing that contains zero metals. PVC is a polymer of vinyl chloride and is insoluble in most organic solvents. Such diffuser line, de-icing hose or bubbler line, being constructed of vinyl resins, which are used in soft flexible films for food packaging and in molded rigid products, such as pipes, fibers, upholstery, and bristles, is a more environmental choice. Plus, the ability of such new diffuser tubing to remain flexible in cold temperatures makes it's use as a deicer tubing much more practical.

While the installation of such a dock bubbler system can be more labor intensive than the relative ease of installing a dock deicer, there are advantages.


A dock bubbler, because it uses an air compressor or regenerative blower, will cost less in electrical consumption compared to an ice eater agitator. Submersible motors run from 3 amperes to over 20 amperes depending on the horse power of the motor. An air compressor for a dock bubbler will run between 2 and 10 amperes.

When using diffuser lines to protect your dock from ice damage there will be some fairly common installation procedures: place the air compressor in a ventilated cabinet or shed. Some turnkey deicer systems come standard with a lockable cabinet designed to resist salt water and rust but some cheap deicers or homemade deicers do not include or even mention the need for a protective housing for the compressor. In our northern climates where winter temperatures near the Great Lakes can be a bone chilling minus 30 degrees for weeks on end it is essential to protect the compressor.

I have seen some inexpensive dock Bubblers that appeal to the do it yourself deicer types that claim that the compressor can sit on the dock without worry but that is a recipe for disaster! The compressor could be damaged by severe weather or in the case of a power failure could be destroyed by the freezing of any condensation in the compressor housing so don't be fooled into thinking a small dock can use a small linear air pump that sits on the end of the dock.

From the blower or air pump a weighted line runs into the water. The line can be buried but if you are using a thick walled and high bore airline you can often get away with surface layout. At the end of your airline you attach the diffuser line, de-icing hose or bubbler line or diffuser line which typically runs the length of the dock in need of protection. I sometimes recommend running multiple lines of tubing or a perimeter loop depending on the layout of the boathouse and boat slips involved.

Remember that variations in depth can affect the bubble flow of the diffuser tubing so it is better to use multiple lines if there are major deviations in depth around the marine or private dock. Sometimes even a variation of a few feet can inhibit the correct flow of air in a tubing. Since one PSI is equivalent to 2.3 feet of depth a difference of few feet could mean that air flow in the weighted tubing is restricted in the deeper areas and no bubbles are being released.

I have seen dock bubbler systems that include single lengths of tubing meant to be placed in a loop of over 400 feet and I have often seen large areas with no bubbles in such installations especially when undersized linear compressors are used. The temptation to buy a cheap bubbler are everywhere on the Internet but it is important to understand the limitations of the technology before leaning towards buying the cheapest system.

Of course, in larger marina projects, where hundreds of boat slips are involved and the dock structure is hundreds of feet of complex maze-like boat stalls a larger, more professional grade system is required. In projects like these we will install large high pressure, high CFM compressors to feed multiple lengths of 1/2 inch or 3/4 inch diffuser tubing. 3 HP to 5 HP compressor are not uncommon using a series of control manifold valves to control the airflow into multiple lines of diffuser bubbler hose.

Regardless of the system you choose it is wise to control the operation of the dock deicer or dock bubbler with a thermostat control that will only initiate operation of the motor when freezing temperatures warrant operation: usually when the air temperature is gist below the freezing threshold. These inexpensive thermostats measure the outside air temperature and engage the air compressor or submersed thruster only when it is required. Another benefit of using a thermo control unit are the savings in electricity costs associated with the deicer.

Building your own deicer, do it yourself dock Bubblers

Saving money is something most of us want to do and when confronted with the cost of a commercial de-icer I often hear people ask how they can build a cheap deicer or as me how to build a dock bubbler. It can be done but before you consider taking on the task ask yourself if it is really worth the time and effort to buy the parts required and, of course, the actual labor it entails to build a pond bubbler.

If your goal is to protect your dock and eliminate costly repairs from winter ice damage then you should weigh the cost benefits of purchasing a pre-designed system from a local expert. If you are gung-ho about doing it yourself it is really not rocket science! Building a dock bubbler involves buying a cheap pump, adding some airline, and then adding a diffuser hose or even diffuser discs at strategic points under the dock or boat slips. I've seen small deicers built for less than $600 dollars but I've also seen such systems fail due to poor design and costly boat and major dock repairs resulting!

Using standard PVC plumbing pipes and drilling holes with a hand drill is one way to avoid buying professional grade diffuser tubing but one errant drilling of a hole can result in catastrophic failure of the system. Pumping air through an open ended pipe, creating large coarse bubbles, will work to an extent but often the results are hit and miss.

Today's systems have undergone years of testing and while the temptation is often there to build a homemade bubbler is often nagging at our thrifty instinct I have seen such desires lead to more expenses that would have been involved in buying a dock bubbler from a reputable and experienced supply store.

Buying a dock bubbler or a de-icer
Buying a dock bubbler or a de-icer requires a certain level of expert knowledge. The Internet is full of websites that sell dock Bubblers and promote their simple systems and most claim that they do the job without issue. I have seen disappointment in many purchases because the retailer was more keen on selling their product than actually customizing a bubbler system to meet the specific needs of the clients particular situation.

In my years in helping solve pond issues I have seen my share of deicing projects. I don't sell de-icers; I leave the final shopping to those with the hard earned money. There are so many options when it comes to dock deicing that it is crucial to use due diligence and to look for the best deal. But beware, the best deal isn't always the cheapest. I have seen some people save a few hundred dollars by buying a cheap deicer on eBay but then they got no service or tech support when things go wrong. My advice has always been: deal with a company that does more than sell products; make sure they have an actual store, with experienced technicians and a track record of knowing what they are doing. There is more to doing the right thing than saving a few dollars; getting good advice and information is worth much more in the long run. See our Bubbler Packages.

Ice Away
http://www.arbrux.com

The ice-away product is along the same lines as the ice eater and the Kasco systems. Another variation which left our reviewers looking at a few Canadian websites that did seem to specialize in Canadian deicing companies. The product itself left some of our test subjects a bit unimpressed but the price points were good and the websites offering the product seemed to be specialists in dock care so they did receive a good rating.

Arbrux Deicers from Arbrux Limited are a manufacturer of De-Icers in Canada. The Arbrux de-Icers are more expensive than Kasco units but they are still known for its reliability and efficiency. The De-Icer brings the warmer, deeper water from the bottom of a body of water to the surface to create open water by utilizing a propeller to move the water at a rate of 500 gallons per minute.

The ˝ HP De-Icer will generally keep a 40’ diameter circle open when the unit is placed 5’ below the surface of the water. Positioning of the De-Icer depends on the area/structure being protected. A De-Icer installed in a sling mount formation is ideal for boats and boat houses.

When slung between two mooring points, the De-Icer has less potential to oscillate. For areas with one mounting point, the De-Icer should be hung by a single chain. A float mount is also available for Deicers that are being used in areas without a mounting point available. For Installation after freeze up, the De-Icer can be installed through a hole that has been augured in the ice. This is convenient for mid winter installations.

The De-Icer comes standard with hooks and ropes for hanging. The use of a Franklin, stainless steel, water cooled and water lubricated motor eliminates the concern for oil leakage into the water while allowing for a maintenance free product. Their specially designed propeller and drive structure (both made from reinforced Zytel) create a high water flow while protecting the propeller and power cord from damage. Arbrux Deicers are fully ETL approved. They meet UL and CSA standards for safety. Arbrux Limited’s Deicers come standard with 1/2hp, 120V Stainless Steel Submersible Motors and either 7.5m (25’) or 15m (50’) power cables. Other voltages, Hp and cable lengths are available.


From the website:
"ICE-AWAY's high speed motor-driven propeller brings the warmer deep water to the surface. It is diffused upward and outward into a circular area equivalent to approximately 8 feet in diameter - for every foot of propeller depth! A 1/2 HP ICE-AWAY with a 25' cord placed at 5 feet of depth will- in most cases keep a 40 foot circle of water ice-free during the winter months. There are optional cord lengths and HP models. The price of a 1/2 HP ICE-AWAY unit with a 25' power cord is $689.95 plus GST and PST. To ensure proper operation, these units should be monitored during the winter months. Changing water levels in the lakes could expose the de-icer unit and result in a burned out motor. De-Icer units need to be kept at proper depth for maximum performance. Power outages that drop breakers will need to be turned back on, to restart the de-icer. Nothing should be left unattended for a long period of time. "



A clear and concise website offering unique systems and custom designed dock protection systems. While no pricing was available the website offered a good supply of information and our review teams found the information was presented in a professional manner. Large and small systems were presented with examples of how they would personalize a system based on client needs. Also an authorized Canadian Kasco Dealer.

From the website:
Using diffuser line, de-icing hose or bubbler line to Keep your dock free from ice We recommend two different types of systems to prevent ice from forming around a dock a "dock bubbler" type or a submersed motor type; one uses a length or several lengths of air diffusing diffuser line, de-icing hose or bubbler line under or around the dock to circulate the deeper warmer water. A low cost compressor on the dock or nearby feeds air to a length and the rising boil of active bubbles bring warm water to the surface where it keeps ice from forming. Even a small linear compressor, which consume very little electricity, can produce enough air to create an active circulating movement under your dock due to the low operating pressure of our new air diffusion tubing.
