Industrial ovens are an example of a special application of
radiant heating. Heat developed by the radiating tubes warms the objects inside the oven. By means of conduction, these objects cause water molecules to evaporate from their surface. Sometimes it is sufficient to heat an object at a particular temperature – in any case, a thermostat controls the heating process. The radiating ovens built by
FRACCARO do not use ventilated air to ensure savings in energy costs. This is clearly shown by the fact that it is sufficient to heat the surface and not the whole object.
Radiating oven systems have been successfully created for the purpose of drying marble, for providing high thermal gradients to metal pieces in mechanical processing industries, and for surface heating of freshly painted materials. Each system is designed according to the heating requirements needed, and it is built with modules of variable thermal power from 10 kW to 100
kW.
Heating by incandescent heaters is the best technique for large and high rooms. The heater consists of a Venturi pipe and a gas injector. Gas injection speed causes a drop in pressure so that the quantity of air required for correct burning is drawn in. The air-gas mixture is delivered to the mixing chamber and is spread along the entire surface of the heat exchanger. The latter consists of a set of ceramic plates, which, warmed to a high temperature, overheat and radiate the surface areas below. The heater is equipped with a mirror reflector for directing radiation.
All the products can be easily assembled thanks to their aptitude for rapid and safe installation. Every qualified assembly team is able to perform the installation of the whole system in a very short time. |
