Areas of application

Considering the difficult chemical conditions with chlorine and fluorine in the waste gases, the use of salt when scraping off the slag or the dust produced when melting down scrap, the performance and durability of a recuperator are crucial.

Aluminium melting furnaces have to maintain high temperatures in order to melt the aluminium which requires a considerable amount of energy. The AluFlow can reduce this considerably.

Thanks to the variable distribution of its pipe systems across materials of different qualities and targeted control of the pipe wall temperatures, the AluFlow can withstand the difficult conditions in the best possible way.

Simple principle
- High resistance

The convection recuperator can be used in all types of furnaces, even if the waste gases contain aggressive substances or dust. Even under these conditions the AluFlow can achieve high efficiency and good durability.

Minimum radiation
- maximum efficiency

Ceramic insulation

The layer of the ceramic insulator prevents the heat energy from radiating out of the recuperator, thus achieving even greater efficiency.

Low-maintenance cleaning

If the exhaust air contains dust, various cleaning options can be provided to enable continuous operation and maintain the performance of the recuperator.
