PRODUCTS Croll-Reynolds specializes in custom-designed air pollution control equipment featuring wet technologies due to their self-cleaning nature, low maintenance, small footprint and high performance. Our product line of wet scrubbers and gas absorbers can be utilized as stand-alone devices for single purpose applications or combined together for collection of multiple pollutants. Wet Scrubbers
Jet Venturi Scrubbers
High Energy Venturi Scrubbers
Multi-Channel Bed Scrubbers (MCBS)
The Croll-Reynolds Multi-Channel Bed Scrubber (MCBS) is designed to collect particles above 2 microns with 99.9% efficiency. Often used as a pre-cleaner for electrostatic precipitators or scrubbing systems, the multi-channel bed system utilizes a turbulent layer of liquid, air, bubbles, and mist to scrub toxic gases, to perform gas cooling, odor control, and particulate removal. EtO/PO Scrubbers
Ethylene Oxide gas (EtO) is used to reduce or render inactive microbial populations in sterilization processes. EtO sterilizes materials and products that would be damaged by conventional sterilization techniques which employ heat, moisture, or radiation. Propylene Oxide (PO) and Ethylene Oxide are also used as precursors in the production of a number of critical chemicals.
Conventional scrubbers are limited to low NOx removal efficiencies due to the nature of the aqueous absorption chemistry involved. Croll-Reynolds' patented "Surface Active" media effectively overcomes those limitations -- without the need for exotic or expensive chemicals or a costly and complex operational scheme. Mercury Scrubbers
Specialized scrubbing systems are available for mercury removal and separation for complete recovery. This patented process utilizes new developments in high voltage technology to achieve complete recovery of mercury. Gas Absorbers Packed Tower Scrubbers
Multi-Rod Deck Scrubbers (CR-5)
Croll-Reynolds Rod Deck Scrubber is a multi-stage chemical absorber that will not scale or plug. It operates by creating turbulent layers from the counter-current flow of liquid passing downward and the gas rising upward between the multi-rods.
Integrated Air Pollution Control Systems We believe a sound air pollution control strategy should employ dry APC technologies to remove large particles and reduce the loading on downstream equipment while wet technology should be employed to cool the gas, minimize its volume, and polish a gas of hard to capture pollutants. Understanding each technology and how it integrates with both upstream and downstream equipment is critical to successful integration. A thorough understanding of the chemical constituants of the flue gas is required to properly arrange, size and design a high-efficiency, cost-effective air pollution control system.

The Jet Venturi Scrubber utilizes a liquid motivated ejector design to entrain contaminated gases, generally
without the need for a blower. The relatively high liquid-to-gas ratio, liquid atomization, and open internal
design provide effective scrubbing of heavily contaminated gases with minimal maintenance and virtually
unlimited turndown capabilities. Its ability to handle wide ranging conditions while removing both toxic
gases and particulate matter makes the Jet Venturi one of the most flexible designs available. It is often
used as a first stage in a multi-stage pollution control system.
The High Energy Venturi Scrubber is ideally suited to the capture of small particles between 0.5 and 3
microns. It's effectiveness in the submicron range is critically dependent on gas-side pressure drop.
This design requires little or no maintenance.
The Croll-Reynolds Packed Tower Scrubber utilizes a vertical counter-current design for highly efficient
absorption of a variety of toxic gases. In addition to its extensive uses in air pollution control, the
Packed Tower can serve as a gas/liquid contactor in a number of process applications. Efficiencies of 99.9%
and greater are not unusual for many scrubbing applications.
