Our ovens are custom-designed to meet your specific requirements
Every production line is unique. Our infrared ovens are custom-designed to adapt precisely to the constraints of each product and each process. This multi-criteria approach, led by our expert engineers, secures your decisions and optimises thermal performance.
Through the ThermIQ™ methodology, we analyse, prioritise and translate your parameters into reliable solutions, ensuring process stability, product quality and industrial safety.
Manufacturers today must master increasingly innovative, high-tech materials with complex thermal behaviour. In the presence of infrared, every material reacts differently, demanding precise adjustment of emitters, power and thermal distribution.
Sopara infrared ovens, incorporating patented technologies, are designed to guarantee optimal thermal performance by adapting to complex shapes, shadowed zones and thickness variations.
High throughput, short cycle times, continuous flow: every Sopara infrared solution is designed to adapt to your production constraints, ensuring quality and process reliability through fast temperature rise and high precision power control.
Certain processes generate fumes or solvents requiring precise airflow and extraction management. Every Sopara infrared solution integrates these constraints as well as the requirements of safety, maintenance and operation.
Every industrial infrared oven is designed with the entire production line in mind: space constraints, upstream/downstream interactions and sequencing of thermal and mechanical treatments.
Every industrial infrared oven enables fine control of production parameters to achieve the optimal balance between power, throughput, quality, stability and process safety.

ThermIQ™ : our structured methodology for designing your infrared oven
Every project is built on our proven ThermIQ™ method, combining analysis, testing, process engineering and training. At every stage, decisions are objectified to de-risk your thermal choices and design an optimal thermal solution.
Multi-criteria product/process analysis: material (thickness, absorption), expected thermal behaviour, line constraints and environment (solvents, ATEX). Our thermal engineers and design office identify critical points and formulate initial hypotheses.
02
Testing
Laboratory or pilot tests to explore different technologies and measure under near-real conditions. This enables decisions to be objectified, risks to be de-risked and investments to be supported.
03
Design and integration
From the validated architecture, Sopara manufactures, assembles and tests the industrial infrared oven under operational conditions (FAT) to ISO 9001 standards before commissioning.
04
Commissioning and training
On-site start-up with a Sopara engineer and training of teams in the operation and control of the system, to adjust parameters, carry out preventive maintenance and guarantee long-term process stability.
Airflow calculated to remain below one quarter of the LEL, low-velocity air supply and air preheating to maintain thermal homogeneity and operate outside ATEX conditions.
Insulating air gap between the hot zone and the external envelope: every heat loss is an energy loss and added cost. Energy stays where it needs to act.
Design integrating maintenance, ergonomics and safety, with facilitated access and simplified dismantling (telescopic rails, modular panels).
Self-monitoring, traceability and system reliability
Instant fault detection, identification of faulty components, multi-level alerts (alarms, SMS, email), measurement redundancy and complete data logging.
Compliance and quality (ISO 9001)
Design, manufacturing and testing carried out to ISO 9001 standards, guaranteeing traceability, reproducibility and compliance with industrial and international requirements.
