In fields of application which are unsuitable for fabric filters Riedel Venturi Scrubbers HNA or absorption scrubbers are used, especially in case of:
- moist exhaust air flows with a risk of condensation
- sticky and oily dusts
- ignitable dusts
- portions of gas in the exhaust air
- ill smelling exhaust airflows
Riedel Venturi Scrubbers embed particles in smallest water droplets and separate them together with the water droplets. So, fine particles of far below 10 µm can easily be separated.
