The vital phase of painting products is the drying phase, in which the paint applied to the workpiece as a liquid layer or in powder is transformed into the continuous, adherent, resistant solid film that guarantees resistance and aesthetic.
A furnace is defined as a closed environment in which the part being treated goes through or stands. It generates and transmits the amount of energy needed to dry the paint completely.
A good furnace must therefore:
polymerize the film according to the types and temperatures required by the painting product applied;
guarantee the absolute observance of safety and correct operation norms, seeing to the elimination of any volatile substances that derive from the painting product;
obtain the maximum energetic efficiency by easily maintaining a sufficient uniformity of temperature inside the furnace itself, avoiding in the meantime environmental heat pollution in proximity of the furnace and reducing thermal dispersion as much as possible (through openings, walls and chimneys);
guarantee a drying environment free of dust and any other element that may contaminate the painted surfaces.
Trasmetal designs and builds convection (natural or forced) and radiation furnaces (with infra-red rays, UV rays, or electron beams); static furnaces or with continuous or cadenced advancement; built on the floor or suspended, and fed with any type of fuel (liquid, gas, heating fluids, pellet, electrical energy).
