Scrubbers
PACKED-BED FUME SCRUBBERS
HEE wet packed-bed scrubbers provide an efficient and practical means of removing acidic and caustic mists
and gases from corrosive exhaust streams. Scrubbers operate on two fundamental principles mass transfer
and impaction by which the contaminants are transferred from the exhaust to a liquid phase maintained
within the scrubber. Once the contaminants are captured they can be neutralized within the scrubber to form
an inert salt that is safely discharged from the scrubber.
• HEE is a recognized leader in the
packed-bed fume scrubber market. Years
of experience and testing have qualified
us to provide a proven product where
quality, scrubbing efficiency and ease
of maintenance matter most.
• HEE's computer-aided process
modeling enables each
scrubber selection to
be custom tailored to
ensure that we meet
your needs.
• Our engineers review
each
application, then custom design
solutions to suit your
specific
requirements. Our
ability to be flexible with custom designs means that
we meet your requirements instead
of asking you to
meet ours.
