Fields of application


Thermal processes as the basis for energy-intensive industries

Industrial thermal processing technology is used for the targeted modification of material properties through the use of thermal energy. It forms a central basis for modern production and finishing processes. The range of applications extends from low-temperature processes of up to 750°C through to high-temperature processes that go beyond 750°C. It is therefore indispensable for numerous industries, including chemicals, pharmaceuticals, glass, steel and cement, food and building technology. Decarbonization is at the heart of future-proof thermal processing equipment. This is made possible by intelligent, scalable, and modular software-controlled automation solutions that can be flexibly adapted to industry-specific requirements. State-of-the-art control technology, stable communication infrastructure, integrated functional safety, and high-performance connection technology create the basis for energy-efficient, safe, and long-term competitive thermal processing technology.

Industrial oven

Heated chambers are used in a wide range of industrial applications, including baking, curing, drying, and heat treatment. Compared to kilns, they operate at lower temperatures. This enables energy-efficient and reliable processes. Typical areas of application include the electronics, pharmaceutical, and food industries. Precise temperature control, uniform heat distribution, and reproducible processes are crucial in this context. Thanks to their flexible design, these ovens can be optimally adapted to different product requirements and throughput quantities.

Melting tanks

Melting tanks, melting furnaces, and blast furnaces form the backbone of many high-temperature processes, such as the melting, refining, and thermal treatment of metals and glass. These systems operate at extremely high temperatures. They enable precise and reproducible process control over long periods of time. The focus is on requirements such as process stability, energy efficiency, and operational safety. Their areas of application range from metallurgy to the glass and ceramics industries and other energy-intensive industries. These industries place high demands on temperature control and system availability.

Boilers

Typical applications include steam boilers, hot water boilers, and steam pressure boiler systems. These closed pressure vessels enable the targeted heating of water or other media to provide process steam or hot water for industrial applications.
The steam generated is used for both thermal process control and electricity generation. Applications range from power stations and the chemical process industry to food production.

The challenges


Thermal processing technology

Thermal processing technology in need of transformation

OEMs of industrial ovens and furnaces, melting tanks, boilers, burners, and combustion systems are facing a profound transformation worldwide. Rising energy and CO₂ costs are putting increasing economic pressure on machine concepts and system operation. At the same time, regulatory requirements such as environmental regulations, the safety of machinery (Machinery Regulation), and regulations like the CRA and NIS 2.0 are tightening the requirements for development, certification, and operation, especially in an international context involving market access in the EU, US, and Asia.

To remain competitive, efficient, and sustainable, companies must contend with high investment costs and increasing pressure to innovate. The focus is shifting increasingly toward the total cost of ownership (TCO): Energy efficiency, availability, maintenance costs, and lifecycle costs are becoming key competitive factors.

At the same time, the shortage of qualified engineering personnel is exacerbating the situation. Development times are getting longer, while at the same time more expertise is required in the areas of automation, software, functional safety, and cybersecurity. OEMs therefore need scalable, future-proof solutions that reduce technical complexity, meet global requirements, and enable sustainable business models.

Norms and standards


Norms and standards for industrial thermoprocessing equipment

Foundations of quality and safety

In the field of industrial thermal processing technology, norms and standards are far more than just regulatory requirements. They are the foundation for safe, efficient, and high-quality systems. These norms and standards bring clarity to the operation, maintenance, and communication of technical systems and form the basis for sustainable innovation.

Internationally established regulations apply for applications in the low and high temperature range. These include the EU Machinery Regulation with the product standard ISO 13577-2/4 (formerly EN 746-2), EN 50156-1/2, and the North American standards NFPA 85, 86, and 87. In an increasingly networked processing world, digital security standards such as IEC 62443 and the NIS 2 Directive are coming into the spotlight. They not only enable protected remote access to critical systems, but also seamless integration with digital platforms such as Proficloud.io. Functional safety and industrial cybersecurity are inextricably linked. An industrial oven or furnace is only safe if its digital environment is also protected. Secure operations can only be achieved with cybersecurity.

The combination of technical standards and digital standards enables location-independent diagnostics, automated update management, and comprehensive performance monitoring. This results in maximum system availability and minimal downtime, and represents a clear step toward smarter and safer process heat.
