Continental Carbon Group deep bed activated carbon adsorbers are designed for greater than 99.9% removal of corrosive gases, volatile organic compounds (VOC), odors, and other hazardous chemical applications where high air flow or high contaminate concentrations exist. To minimize service costs, deep bed adsorbers are sized to provide an approximate annual quantity of activated carbon for the removal of specified contaminants.
The standard configuration for a deep bed carbon adsorber is a horizontal bed (HDB) of 2 to 5 feet deep. To assist in long fan life, systems are designed to pull air through the bed and are generally equipped with pre- and post-particulate filters. For applications where a minimum equipment footprint and/or low pressure drop is needed, we also offer our HECA deep bed carbon adsorber, which utilizes vertical bed design. Standard dimensions and pressure drop data are provided.
Application – Corrosive Gas Elimination
Designed to purify inlet airstreams for pressurization of rooms in which sensitive electronic and mechanical equipment is located. The most accepted method of attaining a purified air stream is to use a deep bed carbon adsorber filled with specially treated activated carbon to remove the corrosive gases. A properly designed adsorber will be able to reduce corrosive gas levels to the point where they are not a factor in equipment failure. With correct carbon selection, all corrosive gases such as hydrogen sulfide, hydrogen chloride, chlorine, etc., are removed at 99.9% efficiency.
Application – Hazardous Chemical and VOC Control
Our deep bed carbon adsorbers are easily modified for a variety of other applications including atmospheric emission control and personnel protection. These durable activated carbon systems are available over a flow range of 100 to 20,000 cfm with flexibility to allow you to adapt to constantly changing regulations from local Air Pollution Control District (APCD), EPA Air Quality Act, OSHA Regulations, EPA NESHAP’s regulations, and ASHRAE’s Indoor Air Quality Standards.
Application – Odor Control
Ninety percent of a person’s life is spent indoors. Studies have shown that in many commercial, industrial, and public buildings levels of nuisance odors and pollutants such as hydrogen sulfide (H2S) can be two to five times greater indoors than outdoors. Odors and irritants increase business costs through productivity losses, sick days, and medical expenses as well as employee and community concerns and complaints. Deep bed units can remove 99.9% of H2S as well as other odors with correct activated carbon selection.
With over 500 different carbon products available, Continental Carbon Group will design a system for you to meet any contaminate concern. We provide the greatest level of technical support from application computer modeling to laboratory performance testing to pilot units for field testing. Many of our deep bed systems and carbon solutions are custom tailored to your exact requirements.
The complete deep bed carbon units, including dust filter, carbon section, final filter, and blower, are available in capacities from 100 to 20,000 cfm and may be customized with respect to carbon bed depth, guard beds, dampers, pressure gauges, etc., to meet your requirements.
Deep bed adsorbers operate in one of three modes: outside air only, full recirculation, and recirculation with outside air make-up. They provide greater than 99.9% removal. Provisions to preclude bypass in the unlikely event of bed settling are incorporated in the design. The system utilizes a gasketless, continuously welded housing of a high-quality stainless steel to preclude the bypass of contaminated air around the carbon bed. The fan assembly comes with a severe duty, high-efficiency motor. Motor speeds are kept to a minimum to ensure quiet operation and maximum life.
The deep bed low maintenance, activated carbon adsorber system is also configured to enable you to monitor carbon usage and take the guesswork out of determining the remaining carbon bed life. Sample ports upstream can be used to test for inlet corrosive gas concentrations, while the downstream sample port indicates final outlet concentrations. Three sample ports located evenly throughout the carbon bed indicate the location of the mass transfer zone and remaining amount of unused activated carbon in the system.
Complete Systems and Services
Continental Carbon Group will engineer your deep bed carbon adsorber as a complete unit operation. Systems can be manufactured to include fans, motors, dampers, isolation and bypass pre- and post-filters, controls, and exhaust stacks so that all you need to do is provide the inlet connection. When in service, we can provide sampling of the carbon bed to test for remaining activated carbon life to assist in developing an activated carbon exchange schedule. Once the carbon is spent and needs to be exchanged, our field service team will remove the spent carbon and install fresh carbon in a single day to minimize downtime to your operation. We will assist you in profiling the spent carbon and arrange that the spent carbon be recycled at one of our plants, removing your liability. Continental Carbon Group offers these products and services so that you may “one-stop shop” and hold one vendor accountable for your activated carbon system.

Making Air Safer and Cleaner
Wet activated carbon removes oxygen from air, causing a severe hazard to workers inside carbon vessels. Confined space/low
oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable local,
state and federal guidelines.
