Heat exchanging elements
We can not imagine modern furnaces without good heat exchanging elements. They save up to 40% of energy, which is used for preheating of the fresh air that comes to the furnace. In addition to energy saving, honeycomb shaped filters and porous ceramic balls are also good removers (filters) of the dirt, which is a result of energy source combustion in the furnace. Both filters and ceramic balls can be cleaned with water and this way their life time is longer.
We make heat exchangers with different sizes of honeycombs, according to customer's request.
For better airflow on heat exchangers, we can make end steps with hight 5mm.
Different shapes of filters are used in different branches of chemical industry. Shapes of filters can be adjusted to customer's request.
Scheme below shows working process of the furnace with installed heat exchangers

DIMENSIONS OF BALLS: we produce different sizes of CATALYST subPORTING BEDS from Ø 3 to Ø 60 mm. PACKING: packed in bags with 25 kg or big bags with 1 ton.
Here are some basic reasons why you should use our heat exchanging elements:
- - Because we produce ceramic honeycomb filters with different dimensions and from different materials, to satisfy customer’s requests.
- - Because we have ceramic balls made from high quality material Al2O3 ≥ 99% Al2O3.
- - We have good prices and we keep our goods on stock, so delivery time is very short.
- - We advise and help our customers to choose the correct filling for heat exchangers.
