DEO™ is a regenerative catalyst system for elimination of VOC and odour emissions from industrial processes.
DEO-100™ is tried and tested on a wide range of applications including various industrial processes and waste applications such as biogas production, substrate and sludge holding tanks, hygienization, sewage pipelines, pumping stations and sewage treatment plants.
VOC and odour compounds are eliminated through patented mesh catalyst technology allowing for optimized and compact reactor geometry, large catalyst area and excellent heat capacity.
The unit is low-maintenance, requires no media or media changes and offers significant cost savings and stable performance throughout the lifecycle. Just push the start button and let DEO-100™ do the job.
It achieves a conversion rate of more than 98% of most VOCs, including those that are difficult to eliminate with conventional technologies such as Ionization, Ozonolysis, UV radiation, Scrubbers and Active Carbon filters.

Regenerative two-step H2S and Methane catalysis with DualCat™
DualCat™ is a two-step regenerative catalyst system for removal of reduced Sulphur compounds (e.g. H2S and Mercaptanes), Aromatics (e.g. derivates of Benzene and Toluene) and Methane. These compounds are typically generated in anaerobic conditions such as in anaerobic digestion, biogas upgrading, sludge holding tanks and sewage pumping stations.
DualCat™ is typically more energy efficient than other methods such as regenerative thermal oxidation (RTO) as oxidation occurs at lower temperature. In addition, by reversing the flow through the unit, the thermal energy stored in the catalysts can be regenerated to pre-heat the process gas, further lowering energy consumption. Already at Methane concentrations of around 1 g/m³, the DualCat™ process is autothermal, eliminating any need for external heating.
Centriair can offer DualCat™ for any flow-rate based on customer requirements, however our standard units are designed for 500 to 3000 m³/h. The units are very compact, approximately 25% of the footprint of an equivalent RTO, and can easily be integrated for example in container-based biogas upgrading facilities.
