Cambridge Stationary Water Screen systems are typically designed as a two screens system with a front and rear screen installed in each water intake. They are designed with engineered lifting points and a catch basin at the bottom of the screen to catch debris as it is lifted out of the water for cleaning. Fabricated guide channels are available that are either bolted to the water intake structure or imbedded in the concrete.

Traveling Water Screens are significantly more efficient at protecting downstream systems from harmful debris and they are much easier to maintain when compared to traditional stationary water screens. There is a misconception that Traveling Water Screens are too expensive to install in cooling towers.
The reality is that the up-front costs in new construction projects can be similar between Traveling and Stationary Water Screen systems when a new hoist and trolley system is also to be installed for lifting and cleaning the stationary water screens. When the savings from maintenance costs and protecting downstream systems are included, a cost-benefit analysis will strongly favor a Traveling Water Screen System.
Large Traveling Water Screens that are installed on natural water sources (i.e. river, lake, bay etc.) need to be pulled out of the water for maintenance from time to time. In order to accomplish this without an outage (and while maintaining debris management), Cambridge Water Screen Systems designs and fabricates custom stationary water screen systems that are installed in front of the Traveling Water Screen. These systems can be designed as one complete unit or in multiple sections that are latched together. These custom systems are designed with significant framing and bracing to maintain structural integrity, and with a 3/8” mesh overlay to maintain debris management.
