In recent years, the manufacturing sector has been shifting toward more efficient, safer, and more sustainable thermal technologies. In this context, gas catalytic panels have gained increasing relevance in production processes—especially in drying, polymerization, and material surface treatment across various industries.
This technology stands out for using catalytic oxidation, a process that generates heat through a chemical reaction without producing a flame. In this article, we take a close look at how gas catalytic panels work in modern industry, why they are widely adopted, and the advantages they offer over traditional heating systems.
What are gas catalytic panels?
Gas catalytic panels are devices designed to generate infrared radiation through low-temperature combustion activated by a catalyst. The fuel used is typically natural gas or LPG, depending on availability and application. These panels are installed inside industrial ovens or integrated into production lines and emit heat directly and evenly onto the target surfaces.
Unlike traditional flame-based systems, catalytic panels generate heat without visible combustion. This is made possible by an exothermic chemical reaction occurring on a metal catalyst surface, usually platinum-based, which triggers the oxidation of the gas.
The principle of catalytic oxidation
Gas catalytic panels operate based on a simple but effective principle: the catalytic oxidation of combustible gas in the presence of air. The gas is mixed with oxygen and passes through a porous ceramic matrix coated with a catalyst. At relatively low temperatures (between 180 and 550 °C), this mixture undergoes a chemical reaction that releases heat—without flames, soot, or smoke.
The heat generated is emitted as infrared radiation, typically in the medium to long wave range, which is ideal for penetrating porous materials or treating sensitive surfaces.
Main components and configuration
A typical gas catalytic panel consists of:
- Metal or stainless steel frame for thermal and mechanical resistance
- Ceramic matrix or metallic fiber layer supporting the catalyst
- Gas/air supply system, equipped with safety and regulation valves
- Ignition and temperature control devices for automatic operation
- Optional ventilation units (as seen in BOOSTERCAT®) for enhanced heat distribution
Depending on the application, panels can be installed horizontally, vertically, or at an angle, either in fixed or mobile positions. Their modularity allows easy integration into continuous ovens, treatment booths, or automated production lines.
Industrial benefits
Gas catalytic panels for industry offer multiple advantages, making them a strategic choice for modern production environments. Key benefits include:
1. Energy efficiency
Heat is transferred via direct radiation, minimizing convective losses. This enables reduced gas consumption and maximized thermal efficiency.
2. Operational safety
The absence of open flames significantly lowers the risk of fires or explosions, making the panels ideal for ATEX-classified environments or areas with flammable vapors and dust.
3. Fast thermal response
Catalytic panels reach their operating temperature within minutes, enabling higher throughput and reducing downtime between production cycles.
4. Low pollutant emissions
The catalytic reaction produces mainly CO₂ and water vapor, with minimal emissions of CO, NOx, or other pollutants. The technology can also help eliminate VOCs (Volatile Organic Compounds) during industrial processing.
5. Versatility
These panels are used across many industries: painting, automotive, textiles, food, wood processing, and more. They are compatible with both new systems and retrofits of existing lines.
Typical industrial applications
Gas catalytic panels are used in a wide range of industrial settings, including:
- Drying of liquid and powder coatings on automated paint lines
- Polymerization of resins and adhesives
- Surface treatment of metals, plastics, glass, and composites
- Drying of fabrics and leather
- Processing of MDF, HDF, and solid wood panels
- Sanitization and drying of food products
- Preheating of materials prior to mechanical or chemical treatment
Each sector benefits from specific advantages, thanks to the panels’ adaptability, compact size, and compliance with environmental regulations.
A technology for sustainable manufacturing
The adoption of gas catalytic panels for industry marks a decisive step toward cleaner, safer, and more efficient production. In today’s regulatory and economic environment—where decarbonization and emissions control are crucial—this technology stands out as one of the most mature and practical solutions available.
Investing in catalytic IR systems means more than just cutting energy costs. It allows manufacturers to optimize processes, enhance safety, and improve product quality. Companies like Infragas are setting new benchmarks in industrial heat treatment, combining engineering innovation, sustainability, and high performance into a single, integrated solution.
