Marine growth is a never-ending problem

Barnacles, biofilm, algae, and unwanted marine growth in sea strainers and seawater intake lines is constant problem. As soon as you clean your sea strainer or acid descale seawater lines, marine organisms begin growing again. This biofouling threatens the performance of seawater-cooled equipment in your vessel. Blockages caused by barnacles and mussels can result in air conditioner overheating, high-pressure fault (HPF) alarms, and failure at the worst possible time.

Stop Paying for Never-Ending Descaling Bills.

Descaling your seawater lines and air conditioner with strong acids is a temporary fix to the never-ending problem of unwanted marine growth. As soon as you’re done descaling with Barnacle Buster®, Rydlyme Marine®, and other acids, then biofouling resumes when you turn your air conditioner seawater pump on.

Stop overworking your air conditioners

Biofouling requires air conditioners to overwork, shortening their lifespan. According to Barnacle Buster®, “as growth forms inside the condenser coil, heat transfer will be greatly decreased causing efficiency to drop. This will cause the compressor to work much harder thus increasing amperage draw.”

Stop using harsh acid descalers

Barnacle Buster® and RYDLYME® are made of Phosphoric Acid <10% and Hydrochloric Acid 5-9%. The pH for Barnacle Buster is between 1.0 – 1.25 considered a “Strong Acid”. According to RYDLYME®, the descaler “is non-corrosive, but the application of RYDLYME may expose pre-existing under deposit corrosion (pitting, holes or similar damage) that can result in leaks in pipes, equipment or systems.”

Never Descale Again!

ElectroSea’s patented electrochlorination systems create an environment where barnacles, biofilm, and marine growth simply can’t live. When seawater enters the boat, it passes through a series of electrified titanium plates that are coated with a rare earth metal oxide catalyst. This electrochemical reaction generates a safe and effective level of chlorine, about the same amount found in tap drinking water. With ElectroSea, your pipes remain free of marine growth, strainers stay clean longer, and you’ll never have to acid descale again. Period!

ElectroStrainer Chlorine Generation

Environmentally Friendly, No Additives Required

ElectroStrainer generates a consistent, low level of chlorine; lower than you’ll find in tap water, but enough to keep barnacles at bay. No chemical additives or acids are required.

Continuous, low-level chlorination is a proven anti-fouling treatment and controls the growth of a range of marine organisms including barnacles and biofilms. At such low levels, chlorine is not harmful to the environment. Chlorine has a very short half-life in seawater with two-thirds decomposing back into common salt (sodium chloride) and water in about 1 minute. The seawater that exits the boat is not harmful to the environment or humans.

ElectroSea protects sea strainer, pipework and air conditioners

ElectroSea’s Control Unit serves as the brain of the system and receives real-time seawater flow data from the ClearVis flow sensor. The Control Unit dynamically adjusts power delivered to the electrochemical cell using a sophisticated algorithm that ensures a precise amount of chlorine is generated. ElectroSea is continuously and automatically protecting your sea strainers, pipework, and air conditioners 24x7x365. If the system detects a decrease in flow, “FLOW ALERT / CHECK STRAINER” flashes on the display indicating the basket needs attention. The best part is there’s no scheduled maintenance, no additives, and no chemicals required.

Product FAQs

Installation process

Most installations can be completed in 1-2 days.

Yes! ElectroSea products can be installed while the boat is in the water.

ElectroStrainer is about the same size as a traditional sea strainer.

Certain ElectroSea products can be installed by end-users. Contact ElectroSea for more information.

Chemicals or additives

Seawater flows through titanium plates that are coated with a special metal oxide catalyst. When this coating is electrified by DC current, a chemical reaction occurs and NaOCl (chlorine) is generated.

ElectroSea’s ClearVis contact-less flow sensor measures seawater flowing through the intake. Flow-rate data from ClearVis is sent to the Control Unit and specifies precisely how much chlorine ElectroStrainer or ClearLine should generate in real time.

No chemicals or additives are required. ElectroStrainer and ClearLine electrochemically generate a low, safe level of chlorine directly from the seawater that flows through our systems. There are no chemicals that are added, and you’ll never need to descale your lines again!

Acid descaling does not prevent biofouling and marine growth. It is an expensive process that you have to perform over and over again. If you have ElectroStrainer or ClearLine, then you Never Have to Descale Again!

Maintenance and warranty

ElectroStrainer and ClearLine are warrantied for a period of two years from the date of end-user purchase.

ElectroSea will NOT void your air conditioner, chiller, or pump warranty. ElectroSea is safe to use with any marine air conditioner, chiller, and seawater pump. ElectroSea actually helps your equipment work more efficiently as it keeps your condenser coils free and clear of marine growth. ElectroSea has over 11 million successful run hours on 65+ boat brands.

There is no scheduled maintenance. The Control Unit will tell you if you have “Low Flow / Check Strainer” alert. If so, simply remove the strainer basket and screen and rinse with fresh water.

The electrochemical cell will last two to five years depending on use hours, flow rate, and other factors.

There is a red “cell” light on the Control Unit that will be illuminated at the end of life.

Safe for my boat, air conditioner and the environment?

Yes – ElectroStrainer and ClearLine are safe for your boat. ElectroSea has over 11 million successful run hours on 65+ boat brands and is standard / option on major brands.

Yes – ElectroStrainer and ClearLine are safe for air conditioners with copper nickel heat exchangers. ElectroSea creates about the same amount of chlorine found in tap drinking water. Further, preventing biofouling with ElectroSea is better then frequent “acid descaling,” which actually strips away a small layer of copper nickel each time it is performed.

Yes – ElectroStrainer and ClearLine are electrically isolated and will NOT cause galvanic corrosion.

Yes – ElectroStrainer and ClearLine are safe for the environment and generate about the same level of chlorine in tap drinking water. Chlorinated seawater has a very short half-life with 66% being oxidized in less than 1 minute. Chlorine is safer than frequent “acid descaling” that uses hydrochloric and other harsh acids which are toxic and harmful to humans.

ElectroStrainer and ClearLine require seawater with salinity greater than 20 parts per thousand (ppt). Vessels often encounter brackish or fresh water when cruising inland and from extended storms and freshwater run-off. This low salinity will not harm ElectroStrainer and ClearLine, and they will begin generating chlorine again when salinity is adequate.
