Switchmode power supplies have greatly improved electrostatic precipitator viability and performance compared to baghouses, and NWL PowerPlusTM has emerged as the preferred switchmode supplier for precipitators worldwide. Many ESP manufacturers now incorporate PowerPlus into their designs, and generating stations around the world have successfully retrofitted their old T/R sets with PowerPlus units.
Why PowerPlus?
If you build precipitators:
- Improved performance. Higher average voltage delivered to the fields produces higher particle migration velocities. Greater collection rate reduces stack opacity.
- Integrated system. PowerPlus integrates transformer/rectifier and controls into a single package, simplifying ESP design and product installation.
- Reduced precipitator size and cost. The precipitator volume is reduced due to greater collection efficiencies. A smaller box requires fewer electrodes, plates, rappers and hoppers.
If you operate precipitators:
- Improve inefficient ESP operation. Some coal-fired generating stations have dramatically improved their opacity measurements just by replacing their old T/R sets and controls with PowerPlus.
- Excellent return on investment. Replacing T/R sets and controls with PowerPlus is a very cost-effective upgrade strategy. Some customers have enjoyed kVA savings in addition to improved dust collection, while others have recouped their replacement costs through increased flyash sales.
- After-sales life cycle support. NWL provides complete spare parts, service, and technical support for the operating life of PowerPlus. Visit our service page for more info.
