Advanced Odour and VOC Elimination Technology
ColdOx™ is Centriair’s flagship technology for precision air treatment, designed to eliminate odorous compounds and volatile organic compounds (VOCs) with exceptional efficiency. Using advanced photo-oxidation, ColdOx® breaks down pollutants at a molecular level, delivering superior performance with minimal energy and water consumption.
Key Features
- >98% Odour Reduction – Proven performance across biogas, waste, and industrial applications
- Compact Footprint – Up to 5–6 times smaller than traditional biofilters
- Energy Efficient – Lower operating costs compared to thermal oxidation or scrubbers
- Minimal Water Use – Approx. 30 liters/day
- Low CO₂ Emissions – 95% less compared to incineration systems
- Long Media Life – When combined with active carbon, ColdOx® extends carbon bed life and reduces maintenance
How It Works
ColdOx® uses UV light and oxidation to break down odorous gases and VOCs into harmless compounds. For challenging applications, it can be combined with SulphaRed™ for H₂S pre-treatment and active carbon polishing for maximum efficiency.
Applications
- Biogas and anaerobic digestion plants
- Waste processing and composting facilities
- Wastewater treatment and sewage systems
- Industrial food processing and rendering plants
