How much does an exhaust air purification system for industrial plants cost?

Exhaust air purification systems are known mainly from agriculture - but industrial companies also have to take action against foul-smelling exhaust air. The GIRL (Odour Immission Guideline) provides the legal framework conditions. In addition, mixing plants, warehouses, food producers or plastics processors often have to deal with complaints about odour nuisance from their surroundings due to the solvents used. An exhaust air purification system provides a remedy.

Biological exhaust air purification cheaper and more environmentally friendly

Während in der Industrie Abluftreinigungsanlagen mit Aktivkohlefilter der Standard sind, hat GreenAirSystems 2017 mit den GreenAirPlus®-Anlagen eine neue und weltweit einzigartige, natürliche Alternative für Industriebetriebe auf den Markt gebracht. Mehr über die biologische Abluftreinigung mit GreenAirPlus®-Nebel lesen Sie in diesem Blogbeitrag. GreenAirPlus® ist ein natürliches Konzentrat, das mit Trinkwasser und Luftdruck in einen feinen, trockenen Nebel verwandelt wird. Dieser Nebel neutralisiert Gerüche erwiesenermaßen auf natürliche Weise, ohne Abfall oder Sondermüll zu produzieren. Das ist nicht nur umweltfreundlicher, sondern auch besser für das Budget!

Significant cost advantages with biological exhaust air purification systems

At Journal for Surface Technology a cost comparison between thermal and biological exhaust air purification was published in 2015. Assuming 2000 operating hours/a, 44 000 m3 exhaust air/h and 220 mg VOC/m3 as in the study, the following costs are incurred for your exhaust air purification system in the comparison:

Investment costs From

520,000 for thermal exhaust air purification,
344.000 € for a biofilter,
176,000 € for biological exhaust air purification and
40.000 € mit einem GreenAirPlus®-System.

Operating costs From

52,680 € per year for thermal exhaust air purification,
23,400 € for a biofilter,
29,290 € with biological exhaust air purification and
8.756 € mit einem GreenAirPlus®-System.

You can expect the following energy requirements for exhaust air purification systems:
Compressed air requirement from

20 Nm3/h with thermal and biological exhaust air purification,
0 for a biofilter and
17 Nm3/h bei GreenAirPlus®-Anlagen.

Natural gas demand From

56,840 Nm3/a with thermal and biological air purification and
0 for a biofilter and GreenAirPlus®-Anlagen.

Electricity demand From

163,200 kW/a for thermal processes,
46,920 kW/a with a biofilter,
116,280 kW/a for conventional biological processes and
4.000 kW/a bei GreenAirPlus®-Anlagen.

In comparison, the electrical connected load is

90 kW for thermal systems,
50 kW for a biofilter,
40 kW for conventional biological systems and
nur 2 kW bei GreenAirPlus®-Anlagen.

And finally, the Delivery time represent a cost and decision-making factor: It amounts to

5 months for a thermal plant,
3 months for a biofilter,
2 months for biological plants and
2 – 3 Monate bei GreenAirPlus®-Anlagen.
