Chrome Scrubber Specifications

The C/E-1 Chrome Scrubber is a low energy system which generates less than 8" of internal static pressure. Average water consumption for a 20,000 cfm unit is just 15 gpm.

C/E has no internal moving parts to wear or replace, and chrome can be recovered from both the gas stream and the filter.

The standard C/E-1 is Type I Grade 1 gray PVC, the material recommended for high chrome applications. The estimated minimum service life of a filter is 5 years under continuous use.

Chrome Scrubber Design

  • Housing construction is Type I Grade 1 gray PVC, including internals.
  • Material thickness is 3/16" to 3/8" PVC, structurally- reinforced depending on location.
  • Exterior flanges are PVC, angle welded to housing for standard duct hookup.
  • Interior flanges are PVC, angle and structural material welded to housing.
  • Liquid connections are standard PVC threaded, socket or 150# flanged.
  • Liquid distribution system includes 14 to 18 BETE TF Series or equal open orifice, non- clogging, spiral- type nozzles to provide complete coverage of the eliminator pad faces.
  • Stage #1 packing media is cartridge type patented mist eliminator pad in polypropylene construction approximately 5" thick.
  • Stage #1 irrigation is continuous.
  • Stage #2 packing media is cartridge type patented mist eliminator pad in polypropylene, approximately 4" thick.
  • Stage #2 irrigation is an intermittent (timed) fresh water feed. Stage #2 includes a pressure regulator, solenoid valve and cycle timers.
  • Stage #3 packing media is a cartridge type patented mist eliminator pad, polypropylene construction, approximately 5" thick.
  • Stage #3 irrigation is an intermittent (timed) fresh water feed. Stage #2 includes a pressure regulator, solenoid valve and cycle timers as required.
  • An optional fourth stage includes a single bank of dry media filters capable of handling and operating under a completely saturated air stream. No irrigation is required on stage #4.
  • Cartridge housing is constructed of formed polypropylene channel with handles. PVDF thread attaches eliminator pads to cartridge.
  • Scrubber base construction is mild steel fabricated channel with epoxy coat resistant to chemicals in operational area.
  • Pressure drop across each stage is read with Dwyer (or equal) magnehelic gauges.
  • Inlet and outlet transitions mate with scrubber unit and are structurally- reinforced Type 1 Grade 1 gray PVC.

Standard Model Chrome Scrubber Recirculation System

  • Material is Type I, Grade 1, gray PVC.
  • Tank is external to the scrubber.
  • Removable pump is securely mounted to the tank cover.
  • Pump is one vertical chemical duty centrifugal type, suitable for continuous duty.
  • Pump is single speed, 3450 RPM, 230/460/3/60 TEFC.
  • Tank contains a switch to indicate low liquid level situation by audible alarm and to shut off re-circulation pump.
  • Tank contains all PVC valves, plumbing, and fittings as required.
  • Tank has a hinged access door to allow visual and physical inspection.
  • Tank has one 3" diameter threaded half coupling for overflow.
  • Tank has one 2" diameter threaded half coupling for drain.
  • Pump discharge plumbing contains a pressure regulator for re-circulation flow control and monitoring.
