Air scrubbers cleanse industrial exhaust, smoke, gas, odors, volatile organic compounds (VOC) plus other noxious emissions and particulates. They are one of the primary devices that can help control gaseous emissions. As there are many different types and specifications available, CESCO can help recommend the appropriate air scrubber for a particular application.
Useful for removing contaminated air and hazardous air pollutants, air scrubbers come in a variety of offerings. Among the range of air scrubbers are wet collection systems, dry collection systems, ionizing wet scrubbers, acid-gas air scrubbers, wet dust collectors, and portable air scrubbers.
CESCO engineers are able to coordinate services, e.g. chemical analyses and reactions, airflow design, removal efficiencies, on-site and pilot testing, etc. to provide a scrubber system to meet your requirements. We offer scrubbers and systems that can remove entrained liquids, noxious and toxic gases, reduce total NOx, recover product, remove sub-micron particles, and treat contaminated ground water. We offer scrubber designs that have been used in bench marking EPA MACT standards. We offer scrubbers that may be fabricated from high quality FRP laminates, including Furan, thermoplastics, dual laminates, as well as steel and stainless steel. All scrubbers are available in configurations and materials to meet your requirements.
Types of Wet Air Scrubbers Offered by CESCO:
- Jet Venturi
- High Energy Venturi Scrubber
- Multi-Channel Bed Scrubber (MCBS)
- EtO/PO Scrubbers
- NOx Scrubbers
- Mercury Scrubbers
Jet Venturi Scrubber

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.
For applications where variation in flow require throat velocity compensation to maintain specified scrubbing efficiencies, Croll-Reynolds offers automatic and manually variable throat designs. The automatic throat is used where flow conditions vary widely and frequent adjustments are required. When occasional variations occur, a manually-controlled throat is generally sufficient.
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.
The flooded glass marble bed and air-rotated marbles of the MCBS allow continuous self-cleaning. The low maintenance design operates in the range of 500 to 70,000 CFM with higher gas flow requirements attainable.
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.
Croll-Reynolds' proprietary EtO/PO scrubbing systems utilize absorption and hydrolysis of these oxides to glycols to effectively treat EtO and PO contaminated gases. Efficiencies greater than 99.9% are guaranteed. Fully automated systems are available.
NOx Scrubbers

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.
This technology is particularly well suited for applications where the infamous "orange" plume is produced by high levels of NOx.
