Infrared catalytic gas heaters emit heat through infrared rays and operate with catalytic combustion in total absence of flame. They are innovative systems designed for pre-heating treatments, curing and drying in the most varied industries. These include the paint, textile, wood and food industries. This catalytic technology enables the manufacture of reliable and compact systems, with easy maintenance, low operating costs and quick treatments with respect for the environment.
Infrared catalytic heaters emit thermal energy through infrared rays (IR). Infrared Radiation is a form of energy transmission with electromagnetic waves (infrared rays). Electromagnetic waves travel in straight lines and are not absorbed by the air, therefore they do not heat the volumes and they only transform themselves to heat when absorbed by organic material. This working principle provides significant energy savings and high quality treatments in a short time.
The infrared wavelengths emitted by the heaters can be modulated, changing the catalytic surface temperature. Therefore, infrared heaters are suitable for different applications considering that they have medium-long wavelengths.
Medium waves reach the exposed objects to be treated without penetrating them, they act only on the surface layers. Therefore they are suitable for liquid and powder painting curing, in textile sector, wood applications, the glass industry and in drying processes with many varying substrates.
Long waves have a low penetration capacity, therefore they are particularly indicated in those treatments where a slight heat penetration is desired or in presence of items with high thermal sensitivity (for example plastic, food products, etc.).
It is very important that the emission source has the correct wavelength for the coating or the substrate to be treated. The right choice of the source determines the efficiency and speed of the process.
- Flameless Combustion and ATEX Rated
- Massive energy savings are achievable versus conventional hot air ovens
- Ideal for Powder Coating and Wet Spray Applications
High quality gas oxidation in total absence of flame, as the catalyst activates the oxidation of the combustible fuel at a temperature lower than its ignition temperature.
With consequent possibility of application in potentially explosive atmospheres (ATEX and FM certified heaters are available).
The catalytic heaters have a high performance catalyst able to start-up in a very short time, shortening the pre-heating phase and consequently accelerating the treatment time, with relevant energy saving. The infrared heaters start-up in 10 minutes: it is the shortest pre-heating phase of all traditional catalytic systems present in the international market, assuming the same electric power involved in the start-up.
Absence of CO, NOX and unburnt hydrocarbons (HC)
Catalytic gas oxidation generates exclusively carbon dioxide (CO2) and water vapour (H2O) without emission of carbon monoxide (CO), nitrogen oxides (NOx) and unburnt hydrocarbons (HC).
The temperature of the catalyst surface can be modulated by acting on the pressure of the gas: the infrared rays wavelength is adjustable from medium to long.
With catalytic technology the VOCs (Volatile Organic Compounds), solvents, alcohols and many other polluting chemical compounds are decomposed at molecular level and are dispersed mainly in the form of water vapour (H2O) and carbon dioxide (CO2), as soon as they come into contact with the catalyst surface.
Gas as a primary source of energy is more economic than electricity. Moreover, IR radiation concentrates on the item to be treated. As a consequence, catalytic IR systems involve quicker treatments with low costs.
High Quality Results
- The nearly total absence of air movement reduces possible contamination of the treated surface
- No coating scaling, no wrinkles or bubbles (as in the case of painting curing)
- Homogeneous high quality finishing
