static | rotary | fluidized bed VOC concentrators
DEC.XBC™
DEC.XBC™ VOC concentrators are a useful tool for reducing solvent emissions from industrial processes: these units are a type of air pollution control device that uses a static, rotary or fluidized bed to remove low concentrations of solvents from large volumes of air.
VOC concentrators are the ideal choice for low solvent concentrations: they are designed for situations where the concentration of solvents in the air is between 0,1 and 2,5 grams per cubic meter (g/m3).

What is a DEC.XBC™ VOC concentrator and when do I need one?
A DEC.XBC™ VOC concentrator is an air pollution control device that uses activated carbon, hydrophobic zeolite, molecular sieves or polymer adsorbents to capture solvents from large volumes of air containing low solvent concentrations, typically between 0.1 and 2.5 g/Nm³. It's the right choice whenever an exhaust stream is too dilute and too large in volume to treat cost-effectively with a standalone recovery or oxidation system.
What's the difference between DEC.SBC™, DEC.RBC™ and DEC.FBC™?
DEC.SBC™, DEC.RBC™ and DEC.FBC™ are the three available bed configurations of the DEC.XBC™ family — static bed, rotary bed and fluidized bed respectively. Each is selected based on the specific process conditions and deliverables of a project, such as air flow rate, layout constraints and continuous vs. batch operation.
What happens to the concentrated solvent stream after the DEC.XBC™ unit?
During regeneration, hot air desorbs the solvents captured on the adsorbent, concentrating them into a stream 10 to 30 times smaller than the original air flow. This concentrated stream can then be efficiently treated in a separate system, such as a DEC solvent recovery unit or a DEC thermal oxidizer.
Is a DEC.XBC™ concentrator an alternative to a DEC.LEL™ recirculation system?
No. Despite their flexibility, DEC.XBC™ VOC concentrators should not be considered an alternative to DEC.LEL™ recirculation systems, which serve a different purpose in managing the Lower Explosive Limit of a process.
How do I get a quote for a DEC.XBC™ system?
DEC.XBC™ systems are custom-engineered to each project's air flow, solvent load and layout, so pricing is provided on a project-by-project basis. Contact DEC's Technical Sales & Applications engineering team to discuss your requirements and receive a tailored proposal.
