Air pollution control systems

Air pollution control systems
The company Izoteh provides comprehensive solutions from design, production, automatic control and commissioning of air pollution control systems. Our systems are suitable for cupola furnaces in steel and foundry industries, and production of mineral fibers as well.

Filtering systems

Filtering systems are stand-alone technological units. Our fabric filters and cyclones are intended for high efficiency separation of dry particles from the gas stream. For individual application, we can offer different types of fabric bags, arrangement and ways of cleaning. In addition to the filter, the design of ducting, dampers, hoods and absorbing nozzles is provided.

Wet scrubber systems

Wet scrubbers are effective air pollution control devices for removing particles and gases from industrial exhaust streams in a single system. Dirty gas is introduced into the stream of scrubbing liquid. Afterwards, particles and dissolved gases are collected from the liquid. Wet scrubbers are a main part of SOx control equipment and common in many industries.


Izoteh developed two families of radial fans: straight blade and back-curved family for energy and process use. The fans are made of quality materials and are intended for operation temperatures up to 400°C.

Heat exchangers

Izoteh designs and produces efficient heat exchangers for its own applications. The heat exchangers for large quantities of gases are made of durable materials, feature excellent heat transfer, wide temperature ranges at a reasonable pressure drop.

Cupola waste gas treatment

Coarse and fine particles are filtered prior to high temperature thermal oxidation of exhaust gases from cupola furnaces. Cupola waste gases are rich in carbon monoxide, which is used as additional fuel in the oxidation chamber. Excess heat is returned through blast air into the cupola.

Waste gas thermal oxidation

Gaseous air pollutants are oxidized at high temperatures in brick or ceramic fiber insulated chambers. Our oxidation chambers are designed to achieve sufficient temperature, residence time and turbulence. Generated heat is commonly reused for the heating of process air, oil or water, or steam generation.

Regenerative thermal oxidation

Regenerative thermal oxidation is used in processes where high quantities of hot exhaust gases are generated and efficient heat recovery is demanded. The units are using ceramic heat transfer media shaped into blocks with large heat exchange surface. Our RTO systems have high heat accumulation capacity and chemical resistance, and achieve thermal efficiency between 93% and 97%.
