Industry Solutions
In many industries there are typical processes that in turn lead to industry-specific exhaust air flows. This enables a certain degree of standardization and thus also cost savings. Here you will find an overview of typical industry requirements.

Waste disposal
Complex and corrosive exhaust air flows
Typical pollutants
- Aliphatic and aromatic hydrocarbons, organic acids, inorganic acids, sulfuric acid, Si compounds, odour
Requirements and objectives
- Protect the system from corrosion, avoid dioxins
- Ensure permeability, anti- clogging measures
- 100% availability
Possible solution
- Adoption of outer insulation, use of very high-quality, corrosion-resistant stainless steel, application of inner coating
- Special heat exchanger materials
- Easy access / cleaning openings
- Redundant design for maximum availability
- Further pre- / post-treatment as required

Automobile
