CLEANING OVENS
CLEANING OVENS
The PETRELLI controlled atmosphere CLEANING OVENS have been designed to clear all the elements that contain polymers vestiges, such as extrusion dies, injection nozzles, die plates, filter elements, “by pass” valves, etc… of an effective, safe and fast system. The system involves the complete melting and degrading of the polymers under an inert atmosphere “without oxygen”, and there is no risk of combustion, which makes the Oven absolutely safe.
The Petrelli patended infrared technology insures an immediate heating process (very short pre-heating time, approx 8kW per cycle – cycles that last from 40′ to 2 hours).
Thanks to the PLC system, who controls, the cleaning process, degradation and and damaging of the parts is avoided, due to the elevated temperature (deformation, cracking and charring of the surfaces).
he Oven can be installed anywhere there is a power supply and 8 bar compressed air connection only.
No exhaust system is required, because the furnace works with a catalytic system , which does not allow the release of harmful particles or gases in the air. The Oven is an innovative, highly technological and unique equipment.

Heaters
Infra-red heaters for extrusion cylinders and injection presses, plates for thermoforming machines as well as for a variety of other
applications, are based on the principle of radiation heating with electromagnetic waves.
Ceramic heating bands are still the most common applications for plastics extrusion, due to it’s high quality/price ratio.
Mica heaters offer a high termal resistance and elevated heat insulation at contained costs.
