Procesni Inženiring: Slovenian Expertise in Industrial Thermal Processing
Procesni Inženiring is a Slovenian engineering company specializing in thermal processes, industrial equipment, and energy-efficient solutions for demanding industrial applications. Founded in 1990 and based in Celje, the company has developed from its original work with gas installations and stations into a manufacturer and provider of upgrades for industrial heating systems, ovens, furnaces, and air-cleaning equipment.
With more than 35 years of experience, Procesni Inženiring works with energy-intensive industries including steelworks, foundries, ceramic processing, and mineral wool production. Its portfolio combines industrial thermal processing systems, equipment modernization, and environmental solutions, with a focus on energy efficiency, reliability, and adapting equipment to individual technological processes.
From Gas Engineering to Industrial Technology
Procesni Inženiring began operating in 1990, initially focusing on the design of gas installations and stations. Over time, the company expanded its activities into upgrades and replacements of existing industrial oven heating systems and began manufacturing its own ovens, furnaces, and air-cleaning devices.
Today, the company develops complete equipment solutions, covering processes from design and 3D modelling through thermal and technological calculations to manufacturing, installation, software support, and start-up. This integrated approach enables Procesni Inženiring to work on complex projects while adapting equipment to customers' existing production processes.
Its headquarters are located in Celje, Slovenia. The company emphasizes technical know-how, flexibility, and cooperation with reliable partners, while also providing technical support after equipment installation.

Industrial Furnaces and Thermal Processing Equipment
A major part of the company's portfolio consists of industrial furnaces and ovens designed for different high-temperature processes. Procesni Inženiring develops equipment for industries such as steel, glass, ceramics, chemicals, brick production, tyres, metallurgy, and sintering. Depending on the application, these systems can support processes including annealing, tempering, normalization, sintering, nitriding, carbonitriding, baking, and preheating.
The company offers different furnace and oven configurations according to technological purpose, heat source, chamber design, and heat-utilization method. Its equipment includes solutions for temperatures below 600°C as well as systems reaching substantially higher operating temperatures.
This flexibility allows industrial thermal processing systems to be developed around the material, production process, and required operating conditions. Procesni Inženiring can also upgrade existing heating systems, helping customers modernize equipment without necessarily replacing an entire production installation.
Industrial Dryers for Process Applications
Procesni Inženiring also develops and manufactures industrial dryers for applications where controlled drying is an important part of the production process. These solutions can be adapted to specific materials, operating conditions, and production requirements, complementing the company's broader portfolio of thermal processing equipment.

Air Pollution Control Systems and Energy Efficiency
Environmental performance is another important area of Procesni Inženiring's activities. The company manufactures air-cleaning equipment based on thermal oxidation, including thermal oxidizers and regenerative thermal oxidizers, which are used to treat polluted air generated by industrial processes.
Its air pollution control systems are designed for applications involving pollutants such as volatile organic compounds, solvents, and other emissions. Thermal oxidation uses controlled high-temperature treatment to reduce pollutants in industrial exhaust streams, while regenerative systems can use heat recovery to improve thermal efficiency.
The company's environmental approach is closely connected with its broader focus on efficient industrial processes. By combining emission treatment with energy-conscious engineering, Procesni Inženiring develops industrial thermal processing systems that can support both production requirements and environmental objectives.
Customized Engineering for Demanding Industries
Procesni Inženiring does not limit its work to standardized equipment. The company emphasizes customized engineering based on the customer's technological process, production requirements, and existing infrastructure. Its solutions can include new equipment, reconstructions, energy upgrades, burner systems, and industrial hall heating.
The company's engineering capabilities cover the complete project cycle. This includes planning and modelling, calculations, manufacturing, equipment installation, software guidance, and commissioning. Such an approach allows individual components to be considered as part of the wider production system rather than as isolated pieces of equipment.
For companies requiring industrial furnaces, the ability to adapt heating technology to a particular production process can be especially important. The same applies to air pollution control systems, where the characteristics of the process air and the type of pollutants being treated influence the appropriate technical solution.

A Slovenian Engineering Partner for Industry
With more than three decades of experience, Procesni Inženiring has developed from a specialist in industrial gas systems into a broader engineering and manufacturing company. Its activities now cover industrial thermal processing systems, furnaces and ovens, thermal oxidation equipment, burner sets, heating systems, and technological and energy upgrades.
The company's combination of engineering, manufacturing, installation, and technical support allows it to address projects from individual equipment upgrades to more comprehensive industrial solutions. Its focus on energy efficiency and environmental performance is also reflected in its development of air pollution control systems and highly efficient energy systems.
For customers requiring industrial furnaces, the company's ability to combine equipment development with engineering and installation provides a comprehensive approach to demanding thermal processes. Its experience with industrial heating and environmental technologies provides the foundation for solutions adapted to specific industrial requirements.
From its base in Celje, Procesni Inženiring continues to work with demanding industrial customers seeking reliable and customized technology. Its experience with industrial furnaces, air-cleaning equipment, and energy-intensive production processes supports projects where technical performance, efficiency, and environmental considerations all play an important role.
