Beaudrey - Model W -Debris Filters

The water enters the cylindrical, flanged spool piece with a rotating screening wheel divided into a number of deep, radial, debris-collection compartments. The downstream face of the compartments is fitted with the patented low head-loss NOCLING™ screening panel which is also fish-friendly, jellyfish and fiber-proof.

The water flows across the NOCLING™ element and the debris are arrested and stored in the compartments. When dirty (head-loss or timer actuation), the wheel starts rotating. It is driven by a peripheral gear and pinion device.

Each compartment passes in front of an upstream scoop which is connected via the flushing valve and pipe to the downstream side of the condenser.

The condenser head-loss provides the hydraulic head to create the backwash flow. All the debris are removed and sent to the condenser outfall.

• Improves the efficiency of condenser tube ball-cleaning systems
• Virtually no maintenance
• Fully accessible from the condenser water box
• Can handle any type of debris in large quantities
• Backed by over 80 years of experience and over a thousand references

• Inspection manholes
• Debris concentrator / collector
• Ball-injection branches
• Support saddle
• Seismic qualification
