Thermal processing ovens
“Industrial ovens constructed according to your wishes, implementing efficient technological solutions with high energy standards.”
Industrial ovens are used in high-temperature processing of raw material that may be in the liquid or solid state of aggregation. They are used in different industries: steel, glass, ceramics, chemical, brick, tyre, metallurgy, sintering etc.
They are used in different heat treatment processes: tempering, normalization, annealing, sintering, nitriding, carbonitriding, baking, tempering, or for heating prior to smithing, pulling, improving the structure of products and altering their physical properties.
Industrial ovens can be classified based on several different criteria, most commonly based on:
- technological purpose (melting, heating, heat processing, sintering, drying)
- heat source (gas, mazut, coal, electricity, no external heat source)
- chamber design (cave, line, rotary, tunnel, chamber)
- based on how the heat from gas emissions is utilized (recuperative, regenerative, without heat exchangers).
However, there are also additional classifications of industrial ovens – e.g.: based on heat transfer, how the oven is loaded, how the heat is re-used etc.

Ovens for heating products bellow 600°C
“For heating products to the prescribed temperature. Air flow ventilation. Mineral wool. Double ceilings and walls.”
Intended to heat products to the prescribed temperature. The evenness of products can be achieved through mixing the oven atmosphere with the air flow vents. Heating time depends on the material demands, they are the basis for determining the size of ventilators and gas burners. Ovens are insulated using mineral wool to prevent heat loss. They are equipped with a double ceiling and walls ensuring proper air circulation. The supply and return air ducts have temperature sensors built-in for each zone.
Chamber oven bellow 600˚
Chamber oven for heating products loaded on carts

Continuous oven for paint finishing and baking
“The ideal combination of infrared heaters and ventilation systems with burners for a quality paint finishing and baking.”
The oven is intended for colour curing after powder coating. The dyed pieces travel through the oven, which is in fact a heating tunnel. Transport takes place with the help of a chain transporter on the oven ceiling outside of the heated area.
Heating is done through a combination of infrared heaters that heat the surface quickly, as well as ventilation systems quipped with channel burners. Infrared heaters are placed throughout the oven interchangeably and also heat the side of the channel in the interim between two pieces. As a result, the outside surfaces are heated quickly as well. This method of curing/paint finishing is suitable for product with a large exterior surface.
The products then travel along the other part of the oven where the paint finishing process end with the help of convection – with the help of the heated air circulating through the dryer, the infrared channel burner heats the air.
Ovens for heating products at temperatures above 1000˚C
“Precise insulation selection. Impulses for the evenness of the product.
Radiant burners for higher temperatures.”
High-temperature ovens are equipped with a frame and appropriate insulation. The type of insulation is carefully selected based on the atmosphere (reduction or oxidation), temperature and the type of oven (continuous or chamber). Insulation can be done by using different types of refractory ceramic wool (up to temperatures of 1260°C, 1430°C or even 1600°C) or grog brick of different shapes and qualities as well as refractory concrete. The evenness of products is guaranteed through the right amount of high-speed burners.
The smoke fumes that are released into the atmosphere from the mouth of the burner act as an atmosphere mixer due to the high speed of release and the types of impulses. With extremely high-temperature ovens, where the work temperature can exceed 1200°C, radiation is the main transmission tool. This is why with such ovens we use special radiant burners. They enable the heating of large radiant surfaces e.g. ceilings and walls.
Ovens can be heated either directly – products can come in contact with smoke gases – or indirectly, where the heating of the products occurs indirectly (such as through the use of radiant pipes) in the required oven atmosphere (reduction, oxidation). The unique characteristic of high-temperature ovens is the use of recuperative and regenerative burners that allow for greater energy efficiency.
Chamber oven above 1000˚C
“Mixing atmosphere with a strong impulse.”
To achieve evenness, chamber ovens have built-in burners that mix the atmosphere with strong impulses; in a specific part of the curve they reach 70 % efficiency or fail to work. Sometimes such ovens require a specific atmosphere (oxidation, reduction or a combination of the two – oxidation at the beginning and reduction towards the end).
The temperatures rise and fall along the curve. The unique feature of such ovens is insulation, as each cycle needs to be heated and cooled-down again, constituting significant energy loss.
Oven volume: 3,5,7 m3
Sealing: With a ceramic string and sand by the troley.
Insulation: Ceramic wool, a combination of brick, concrete and soft insulation.
Continuous oven above 1000˚C
In such ovens the products travel through the oven and are heated, as well as, depending on the process, cooled-down inside the oven. Transport through the oven can take place either through the use of carts, roller hearths or chains, carriers and slats.
Rotary oven
“For direct or indirect heating of fine materials.”
Intended to heat fine materials such as balls, chippings, mulch, pallets etc.
The materials enter the rotary drum in the front part, they are then heated and finally exits the drum heated through an opening.
The heating can be executed directly – with the burner in the centre of the drum – or indirectly with burners in the coat.
Rotary quenching oven
“Recuperative burner and good sealing for a high energy efficiency.”
In entering the drum the granular material shuts down the air supply to the drum with its density – ensuring a controlled atmosphere in the drum.
The area containing the most granular material can be heated through a special angle of the burner.
The angle and the number of baffles define the speed with which the granular material moves through the drum.
Material can fall into the water or thermal oil. Energy efficiency is achieved through proper sealing and the use of the recuperative burner.
Due to the specific way the sensors are built-in, we can ensure the evenness of the material, despite the extremely varying demands of clients with regard to the granular material flow.
Quality granular material can be created even with 1:3 flow oscillation ratio.
Adjustable temperature to:
Granulate temperatures:
