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.

What's Included?


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.


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 is the proud designer of the Automated Coanda Screen Cleaner and provides services from design to commissioning and then full support during operation. We will be with you every step of the way.

What's Available?


Our sophisticated PLC programming is designed to integrate with your existing plant HMI. Contact us about integration details and customizing the PLC make and model to your site. We can also supply “headless” systems with no control box if you have a distributed control system and motor control equipment at your intake.


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!

Current Installations

Llangower, Wales, 100kW

“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.”

This picture shows Automated Screen Cleaner running over 50% of the screen area for only a few passes after commissioning. Notice the difference that a cleaner can make on even a lightly clogged screen!

Haa-ak-suuk Creek, BC, 6 MW

Rumbling Bridge, Scotland, 500kW

 “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.

Since installation of the cleaner 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.”

  – Hugh Wallace, Developer, Part Owner and Operator of RB Hydro

Skookum Creek, BC, 27 MW

The original development site for the Automated Screen Cleaner. This cleaner has been through several iterations as we have refined the design from a hand-cranked pulley to a drive that is fully integrated into the plant control system.

“We rely entirely on the cleaner to maintain production. It is the only way to make nameplate capacity safely. Prior to installation production was unpredictable.”

Brandywine Creek, BC, 7.8 MW

A challenging installation, with long, angled support posts needed to maintain the brush at the correct angle to stay in full contact with the screen.

Trethewey Creek, BC, 21 MW

Fire Creek, BC, 23 MW


Our longest span to date, with a 26m static line between the two support posts.
