IR Gas Catalytic Drying : time & energy savings, environment respect, custom-engineered solutions and high quality results. The introduction of gas catalytic drying into the collision repair market has revolutionised the industry.  No longer is it necessary to heat hundreds of cubic feet of air, simply to dry a layer of paint. Natural gas or LPG powered industrial catalytic IR heaters that emits infrared heat through a safe, flameless heater technology which produces a uniform low intensity heat. This heat is in the form of medium wavelength energy which is readily and evenly absorbed by a wide range of organic materials, offering substantial energy cost reduction with rapid payback.




GTD catalytic systems release water vapour and carbon dioxide during flameless combustion, they do not produce CO (carbon monoxide) and NOx (nitrogen oxides). Moreover, they abate VOCs (Volatile Organic Compounds) with consequent reduction of toxic emissions at global level.  Using a propriety platinum based catalyst, the products of combustion are extremely environmentally friendly. The absence of a flame, while maintaining a heater surface temperature 420°C, generates a totally diverse and evenly distributed, medium wave IR across the surface of the heater.
The Catalytic Reaction The spectrum wave directly penetrates the molecule of any paint product instantly bringing cross-linking in a few minutes. The catalytic chemical reaction takes place in total absence of flame, in total safety for human health, even if the panel should enter accidentally into contact with liquids or solvents commonly used in the body shop, as the spontaneous combustion with minimum emissions of CO2.

The system passes natural methane gas through an noble metals catalyst, which then separates the carbon and hydrogen atoms to create energy. That energy is then passed through the front of the catalyst where it mixes with oxygen; the oxygen combines with carbon molecules to create CO2 and with hydrogen to make H2O. The end result is infrared energy that is emitted out of the device.
The GTD catalytic heater is a diffusion type heater, that operates on a chemical oxidation reduction process that reduces the methane or propane gas in the presence of platinum and oxygen, into moisture, carbon dioxide, and produces IR energy from this reaction. The catalytic reaction requires that the catalyst be at a temperature of 90°C. This is achieved from an electrical preheat element that is activated for about 12 minutes. The gas enters the heater panel and is evenly dispersed through a plenum chamber within the heater. The gas is then distributed into the hot catalyst where it reacts with the platinum in the presence of air. There is no flame with the reaction of gas. As such these heaters are approved for heating hazardous areas. Operation



Phase 1 The radiant heaters are made of high performance and long life noble metals. They are pre-heated electrically for a very short time  

Phase 2The injected gas comes in contact with the catalytic mass and oxidises, thereby increasing the temperature of the heaters and causing an intense emission of medium wave infrared rays.
Extraordinary results with GTD® robots

/ Both natural gas and LPG can be used
/ Drying time is reduced by more than 50%
/ Fuel consumption (gas or diesel) is reduced by 80%
/ Productivity increase by 30%
/ Medium wave infrared emission, risk-proof when used on plastic parts
/ Maximum safety is guaranteed by means of anti-detonation, explosion-proof and flameless
heaters thanks to the flameless oxidation
