2.2. Oven general description
The oven has an external structure made of sheet steel painted with epoxy powder coating to
withstand heavy working conditions as humidity, corrosion and salty atmosphere.
The inner hopperchamber is cone shaped, manufactured in stainless steel.
The flux is taken from the hopperchamber through a door located at the lower part of the hopper.
On the upper part of the oven there is a small door for loading the flux.
The main drive and the temperature control board are located in the front lower part of the oven.
2.3. Thermal insulation
Rock wool insulation is installed on the external structure of the hopper-chamber for a better
heat distribution throughout the oven chamber and a better thermal insulation. Insulation is
internally closed by a covering plate.
2.4. Heating elements
The spiral stainless steel heating elements are located into the hopper-chamber in direct contact
with flux. They can reach 800 °C (about 1500 °F) if left uncontrolled.
