Modernizing Your Heat Treatment Plant

Aichelin Unitherm Service: Retrofit

Increase your system’s production performance

A heat treatment system is only as Reliable and Safe as its technical condition. However, as systems age, the risk of downtime, energy losses, and quality deviations increases - the requirements for safety, documentation and process stability continue to grow. Mechanical modifications, electrical modernizations and software upgrades are not optional, but a crucial step to ensure your system operates economically, safely, and in compliance over the long term.

With modern components, optimized mechanics and intelligent process control, you can significantly increase system performance, reduce downtime and ensure reproducible heat treatment results continuously.

Modernization and Modifications

Mechanical Modifications

Mechanical modifications take your heat treatment system to a new level of performance. Through targeted upgrades, we increase efficiency, safety and furnace availability – creating the foundation for stable, energy-optimized and durable processes. Whether performance improvements, energy savings, safety upgrades or complete furnace relocations: our solutions ensure your system operates reliably, economically and is future proof.

System optimization

as part of a continuous improvement process (CIP)

Burner modernization

for higher performance and improved energy efficiency

Component upgrade

e.g. conversion from steel to ceramic radiant tubes

Performance increase

e.g. by increasing burner capacity or reducing cycle times

EN compliance

Safety check and modification in accordance with relevant furnace standards

Optimized thermal insulation

to reduce heat losses

Modernization and Modifications

Electrical Modernization

We modernize the electrical part of your heat treatment plant and prepare it for the future: more powerful, more reliable and significantly more precise in process control. This allows you to benefit from stable, reproducible heat treatment results, higher furnace availability and technology that not only meets but actively supports the requirements of Modern production environments. The following measures represent the recommended scope of such modernization:

PLC upgrades

including Siemens Simatic S5 to S7-1500 or KS98 to modern Siemens PLC controllers

Control system retrofit

FOCOS 4.0 with heat treatment documentation and recipe management

Upgrade to CQI-9 standard

Equipment to meet all technical minimum requirements.

Optimized process control

for optimal control quality, stability, dynamics, and robustness.

Controlled burn-out

for complete, safe, and reproducible combustion.
