Henteen offers the know-how gathered practical experience. In the course of these years we have installed plants for air pollution control for different applications in nearly all industrial fields all over the world. All plants are characterised by

- the reliable observance of the corresponding requested emission limit values, i. e. for particulate, acid crude gases such as HF, HCl and SOX, dioxins / furans as well as heavy metals such as Hg and Hg-compounds
- a reliable continuous operation at lower maintenance
- low operating costs

Below please find, as representatives for a large number of installed projects, some references for the fields of application

- Aluminium industry
- Copper industry
- Brass industry
- Zinc industry / zinc recycling from steel mill dust
- Lead industry
- Industries for further non-ferrous metals

Fire and explosion safety
Potentially-explosive process dust is produced during dry processing or processing with minimal lubrication of aluminum and aluminum alloys. These are categorized in explosion classes St 1 to St 2, depending on grit size distribution, degree of oxidation, humidity and consistence.
The risk of explosion or fire is increased through the accumulation of this dust in machining chambers, particularly where classical dry suction extraction systems are involved.
Deposits of dust permeated with oil emanating from minimum lubrication systems increase the risk of fire.
