Cambridge Water Screen Systems Stoplogs are designed to stop or reduce the flow through a water intake to isolate an area for maintenance such as a cell in a cooling tower or a pump, or to reduce the volume of water.

Depending on the application, Stoplogs can either be designed in multiple sections or as one complete unit. Stoplogs designed as one unit to isolate a pump, will typically have a manually operated pressure relieve valve at the bottom to equalize the water pressure for removal.       

Example of a custom Stoplog and Stationary Water Screen in a cooling tower that were designed to fit existing guide channels embedded in the concrete (top down view shows Stoplog in the rear guide and the Stationary Water Screen with perforated debris basket in the front guide) Note: A custom frame was required for the Stationary Water Screen because the existing guides had not been properly engineered for the size of the required frame based on the open area and flow rate through the water screen.

Example of front & rear view of a Stoplog (16’ tall x 6.5’ tall) in one complete unit without a pressure relief valve. The Stoplog is 1 of 2 that were designed to slow the volume of cooling water flowing into a water intake off a river as part of a EPA 316b regulation compliance project.
