Matching of spectra:
Situated in a range from 2 to 10 microns, the thermoreactor's infrared emission spectrum covers the absorption spectra of organic coating completely and perfectly. This matching of spectra results in an excellent transfer of energy and an evaporation, drying, fusion and polymerisation processes.

Additional convected energy:
This additional energy complements the radiated energy. It is generated and controlled by ventilation on the surface of the thermoreactor. In the design of the tunnel, this additional convection can be increased by a general recycling of surrounding air at controlled temperature and rate.

Recycling of surrounding air:
On each thermoreactor, the recycling of the surrounding air in the tunnel gives you the possibility of increasing the organic solvent destruction rate because of flameless oxidation of the vapour when in contact with the thermoreactor.

Control:
Modulation of the thermoreactor power output is obtained by varying the pressure of the gas supply in the appropriate fashion : direct reading by pyrometer by contact measurement with thermocouple, or by power output controlled by presetting of instrument levels according to the requirements of the workpiece being treated.

Safety :
The total safety of the thermoreactor in the presence of organic solvents (VOCs) has been tested in a special explosion test box (State Laboratory Control CEPr). Because of its combustion efficiency the THERMOREACTOR® generates neither carbon monoxide (CO) nor nitrogen oxides (NOx). EC make N°49AT2539.

 

 

 

 

 

See time saving table

Time saving:
Drying time is always one third to one eighth of the normal time because of the rapid rise in temperature and acceleration of evaporation, fusion and polymerisation processes.

See time saving table

 

Space saving:
This saving always results in a more compact and shorter tunnel, which favours installation where space is limited.

Quality:
Improved finished appearance and paint film hardness occur because of core drying, solvent or water evaporation from inside to outside, and also because of the very quick fusion of powder paint.

Freedom from dust:
Dust contamination is avoided by rapid drying.

Solvent vapour removal:
The solvents (VOCs) in contact with the thermoreactor during the drying phase are destroyed by flameless oxidation.

Energy saving:
The reduction in energy consumption, which can be more than 50 per cent, can be explained by the direct transfer of energy from the thermoreactor to the organic coatings.

Productivity:
Faster throughput resulting in minimal numbers of paint sprayed items queing for THERMOREACTOR® treatment.

Rapidity:
The start-up for a tunnel with a thermoreactor system is only ten minutes.
