Sentry 2000 Scrubber System
for use with chlorine, sulfur dioxide, or phosgene
The Powell Sentry 2000 Scrubber System is one of the most advanced emergency scrubber
systems available today and is for use with Chlorine, Sulfur Dioxide, or Phosgene.
The Powell Sentry Scrubber is a 4-stage, single-pass scrubber with a horizontal
packed bed of high efficiency packing material. The Sentry 2000 can achieve virtually
any stack emission performance desired. Thus, it is possible to control performance
of the system based on any inlet and outlet concentrations and flow rates.
The Sentry 2000 has been subjected to the most demanding testing of any scrubber
on the market. In rigorous testing, the Powell Sentry 2000 surpassed the requirements
of Uniform Fire Code Section 80 and is the only scrubber tested in accordance with
US EPA Reference Test Methods, which are more accurate than continuous gas detector
Performance tested by the nation’s leading air emissions testing organization at
full scale 3,000 ACFM air flow rate with 2,000 lb. releases of both chlorine and
Performance tests witnessed by an independent firm specializing in the application
of fluid dynamics to industrial flow problems. The Powell Sentry 2000 demonstrated
better performance than the 5ppm stack discharge limit set by UFC specifications.
