The first oven with vacuum chamber for die heating was patented by Compes many years ago. Since then important improvements have been introduced in order to keep it as the quality industry benchmark.
Compes OVEN with independent drawers is a technologically advanced system, widely being used in many extrusion plants.
Strong points that make it particularly attractive:
Preheating dies in an oven with perfect sealing and with inert atmosphere, without oxygen, offers numerous advantages in financial, technical and health terms.
This oven allows a simplified and independent handling of each die, protecting the temperature of the other ones already under process.
The die is seated on a supporting carriage with a very limited mass, therefore with low thermal capacity and bland radiation.
The structure with independent drawers saves a considerable amount of energy, because the heat that escapes when you open a single chamber of the oven is much lower than the one lost every time you lift the lid of a traditional oven.
The independence of pyrometry in the drawers allows dies with different temperatures as a function of the type and difficulty of extrusion.
COMPES DIE PREHEATING OVEN ® offers safety, ease of use and considerable cost savings.
By introducing COMPES DIE HEATING OVEN ® in their company aluminium extruders obtain various benefits, from a financial, operating, hygienic and environmental point of view.

* SVPV version advised.
For diameters higher than 600 mm only SVPV version should be used.
The oven is available in various versions:
The use of ventilation reduces heating time by 25%.
The use of vacuum allows reducing nitrogen consumption by about 10 times.
Modular structure with separate drawers, with fron opening.
The choice of drawers quantity is a function of extruder's needs.
Flexible system, allowing increasing the drawers quantity also later.
Possibility to build the oven with stacked drawers for space saving.
Possibility to build the oven with different size drawers.
Guarantee of set temperature for the single chamber in each die point with a tolerance of +/- 3 °C.
Perfect sealing of each chamber, obtained by lining the special rubber gaskets, duly cooled.
The system is supplied in compliance with CE standards or alternative ones.
