Debris filter with redundant reliability
The PR-BW 400 is an automatic backwash filter for reliably filtering macro particles from cooling water flows for turbine condensers and heat exchangers. With its quadruple-redundant drive technology, it ensures maximum availability even under the most demanding operating conditions.
Technology
The PR-BW 400 is the first filter of its size in the world to use pressure-relieved backwash technology. The filter houses four large filter chambers, which can each be flushed individually. Four independent drives ensure redundant operation, so that the cooling water supply can continue to flow uninterrupted if one drive fails. The generously proportioned filter chambers also reliably capture large debris, making them ideal when the degree of fouling is hard to predict.
Your benefits during operation
The PR-BW 400 ensures a permanently stable cooling water circuit, laying the groundwork for economical plant operation:
High plant availability
The filter prevents macrofouling and debris from entering downstream turbine condensers, heat exchangers, and other equipment.
Managing larger debris
The filter also reliably retains larger bits of debris that can pass through the intake structures and clog downstream heat exchangers during severe weather conditions.
No unplanned shutdowns
The automatic backwashing reduces manual cleaning work and minimizes unplanned shutdowns.
Stable efficiency
No rise in the condenser pressure, no efficiency losses in the cooling water circuit.
Flexible installation
Taprogge Solutions
The filter can be installed in any position – horizontally, vertically, or at any angle. In confined spaces, the filter sections can reach directly into the condenser water chambers. The filter is also designed and engineered for use in earthquake-prone regions. The PR-BW 400 has proven its worth in situations where continuous availability and maximum reliability are the highest priorities, particularly in cooling water circuits in power plants and nuclear power plants.
