  • F-105 Wet Scrubbers Installed at Semiconductor Wafer Fab in Singapore
    to treat acidic process exhaust. CSP also required that each scrubber be supplied with an energy efficient exhaust fan. After thorough analysis of equipment features and benefits, CSP selected Duall model F105 scrubbers complete with redundant recycle pumps and Duall NH fans. All equipment
  • Scrubber Systems and Exhaust Hoods Utilize Corzan TM CPVC Construction for Corrosive, High Temperature Processes
    OSRAM-Sylvania Corporation has lighting manufacturing facilities in both Versailles, Kentucky and Luquillo, Puerto Rico. At both locations, high temperature HCl and HF processes are used to etch glass and other lighting components. The process baths are extremely concentrated and operated at
  • MICRO:Industry News:Expansions & Acquisitions (Oct '99)
    towers and exhaust scrubbers. Lab tests and field experience prove that the technology can recycle "a significant portion " of the ultrapure water used by SpeedFam-IPEC's Auriga and Auriga C polishers, according to Lucid. Entegris has finally made its debut following a merger announcement earlier
  • Industrial Gas Cylinder Venting (.pdf)
    A supplier of special industrial gases had a unique problem. Returned cylinders contained small volumes of various toxic gases that needed to be completely vented prior to reusing the cylinders. The exhaust volume was typically very small but the gases were essentially pure contaminants such as SO2
  • Meeting the Production Challenges of High-Brightness LEDs
    One highly effective way to reduce LED manufacturing costs involves switching from wet scrubber exhaust abatement systems to combustion-based abatement technology, explains Mike Czerniak of Edwards. There is a growing movement in the global community to replace the incandescent light bulb
  • Unique Overhead Push Air System Saves $ While Capturing Volatile Acid Mists
    . The process required two new 65,000 CFM fume exhaust systems. The first system utilized a Duall F103-247 scrubber to treat the Nitric/Hydrofluoric acid tank emissions. The second system used a Duall ME-107 mist eliminator, to capture Sulfuric Acid mists from the acid spray, and bar tank lines
  • Quintessential TM Scrubbing System Solves Odor Complaints
    with exhaust fan plugged quickly, choking down air flow, and did not sufficiently remove odors. Duall was contacted to help address the air quality concerns. A primary issue facing the Duall engineers was the fact that Master Chemical was producing a variety of products utilizing proprietary chemistry. Since
  • Drop by Drop: The Difference Between Success and Failure, Pharmaceutical Formulation & Quality Magazine
    quickly. Larger particulates fall to the bottom of the chamber and are collected. Fine particulates that are part of the exhaust gas are collected by passing through an external cyclone, scrubber or bag filter.
