Hybridfiltre
GreenLab Biogas experienced major issues with high humidity in their process air. This led to condensation, rapid saturation of carbon filters, and increased odor nuisances. To establish stable operating conditions and improve filtration performance, they installed an MBS Dehumidifier based on two-stage heat exchange technology.
Stable operation and reduced odor nuisances with a dehumidifier
The dehumidifier effectively reduces moisture in the process air by cooling the air, condensing the water, and returning dry, reheated air to the system. The result is significantly improved operating conditions for both carbon and hybrid filters.
Benefits:
-
Up to 441 liters of moisture removed per day
-
Reduced load on carbon filters and extended service life
-
Reduced condensation and corrosion
-
Stable humidity levels and more efficient filtration
-
Low energy consumption (approx. 500 W per 1,200 m³/h)
Operation and performance
After installation, GreenLab achieved:
-
Uniform exhaust air temperature (20–24 °C)
-
Reduced odor nuisances and more stable air quality
-
Significantly reduced maintenance requirements
-
Improved energy efficiency through heat recovery
Conclusion
The dehumidifier has provided GreenLab with a more stable, energy-efficient, and reliable solution that reduces moisture, protects the filters, and improves air quality. It is particularly well suited for facilities with warm, humid process air—such as wastewater, biogas, and process industry applications.
