. . .
The Automated Screen Cleaner can operate 24 hours a day in any weather to keep your intake clear. Say goodbye to lost production from a clogged screen.
Our Story
Sea to Sky Energy Solutions developed the Automated Screen Cleaner in 2015 at the Skookum Creek Power Project. Necessity is the mother of invention, and we were falling nearly 5 MW short of the plant’s nameplate capacity because leaves, grass, roots, and ferns would clog the intake screen during major storms. It was impossible to keep up with the rate of fouling by cleaning the screen manually, and we were tired of feeling cold, wet, and exposed. Our engineers developed and refined the Automated Screen Cleaner and haven’t looked back since.

With the SSES cleaner, you can say goodbye to unsafe and compromising cleaning tactics to maintain maximum production.
Stop watching production slip while you can’t get there fast enough to rectify it. Never enter a river in spate again. Hang your harness up for good and put your worries to rest that operators won’t get stuck dangling above a dirty screen! No longer will you have to drive to the intake in adverse weather conditions.
An automated cleaner keeps the screen free of debris 100% of the time, SAFELY.
SSES engineers have 30+ years collective experience in the run of river industry. We know what is required of equipment to survive the extreme river conditions at intakes. The automated cleaner is designed with function at the forefront. Robust, reliable and fit for purpose.
This is a video taken showing some extreme flows at Rumbling Bridge. The cleaner maintains maximum production during extreme weather events such as this.
Graham, our controls engineer, has witnessed a tree bounce off the cleaner and continue downstream! Cleaner was undamaged.
The conception of the cleaner came from a desire to end fluctuating uncontrollable power production. Let your investment reach its full potential with the automated cleaner, convert all your available water to power.
Not convinced your missing out? Contact us! We will look at your data, run a conversion effectiveness study and determine if your intake is a good candidate for a cleaner. We are confident the numbers will speak for themselves.
What's Included
THE CLEANER
The Automated Screen Cleaner includes a weatherproof control box, an electrical drive system with a weatherproof cover, a static line to support the brush, a drive line to pull the brush across the river, a return pulley for the drive line, two customized mounting posts, a custom screen cleaning brush, and all the hardware and cables necessary to put it together. No electrical wiring experience is necessary to install the cleaner; all the required cables plug in to ports on the outside of the control box.
CUSTOMIZATION
The Automated Screen Cleaner will be customized to your intake site to ensure that the brush is positioned for full-screen contact. This includes customized mounting posts for the drive system and return pulley, and a brush made to measure for your screen. You have the option to use your own trusted fabrication shop to make the posts to drawings that we supply.

Sea to Sky Energy Solutions has a wealth of experience installing and commissioning Automated Screen Cleaners. We are happy to provide full turn-key installation for your cleaner. Worried about power at your intake? Contact us for innovative low-cost power solutions!
“On commissioning Rumbling Bridge Hydro it soon became clear that frequent and often highly precarious manual cleaning of the coanda intake screen was required in order to achieve production levels commensurate with energy predictions. Often it was simply too dangerous to enter the river and during periods of high flows actual production was sometimes less than 10% of nominal, occasionally stopping altogether. This was entirely due to water borne organic matter clogging the screen. Our health and safety consultant simply couldn’t write workable RAMS and we started to search out to see if others had experienced similar issues and learn from them.
Thanks to Google we found SSES in Canada and soon commissioned a cleaning system from them. Since installation in September 2018 energy losses have been virtually zero and we proudly operate a safe site. Production levels have also consistently exceeded targets. The SSES Screen cleaner has been a fantastic investment which we’d be happy to recommend to anyone experiencing similar safety and performance issues.”
“The cleaner, which has been installed on a coanda screen supplying a 100kW cross-flow turbine in mid-Wales, has had a dramatic impact on the maximum power achievable. Prior to the cleaner’s installation, in high water, when there is a lot of small debris in this river, the screen would become partially blocked after only 30 minutes of operation. Manual cleaning of the coanda at this frequency was impractical. In these circumstances the power would only rise to about 60kW. The installation of the cleaner means we can generally run it much closer to its full power of 100kW.”
– Liam Brown, Managing Director, Greenearth Hydro Limited
“The first Installation of the Automated Coanda Screen Cleaner allowed for the Skookum Power plant to increase power production by 5MW. This technology removes the vegetation that would often clog the screen during high flows where power losses were the most significant. By employing this device at our Skookum plant, consistently reaching maximum power production of 27.5MW is made possible.”
