Thermal cleaning System-Pyrolysis oven

Thermal cleaning system is a thermal conversion of organic materials in an oxygen-poor environment. At a temperature of 380-450°C, the organic materials are converted into smaller molecules.

The macromolecules are in fact decomposed, resulting in pyrolysis gases (ethane, ethene, propane, propylene), pyrolysis oil which contains aromatic components and a carbon-rich residue. The pyrolysis gas as well as the oil is transformed into carbon dioxide and vapor, because of partial oxidation.

The gases released during this process are re-used to decompose the organic material. This cleaning process takes place under highly controlled conditions with a limited oxygen level of approximately 8 percent.

After the thermal cleaning process, 1 kilo of pollution results in 50 to 100 grams of dust remainders, which can be easily removed.
The process of heating and cooling always takes place gradually thereby preventing potential tensions in the parts being cleaned. Depending on the precise level of contamination and size of the part, the thermal cleaning process can take between 8 hours and several days. Thermal cleaning system usually provides a solution for extreme contaminations, which cannot be removed using conventional techniques or deliver inadequate results.

REWINZ can offer pyrolysis ovens (thermal cleaning system) to clean parts contaminated with paint, plastic, rubber, petroleum, oil and grease or any other contaminants containing organic compounds.
