Pyrolysis furnace for thermoplastic and filter parts cleaning
Efficiently clean extrusion and filter parts by removing thermoplastics and mixed plastics without chemical agents, ensuring extended tool lifespans and operational precision in manufacturing and recycling processes.

Cleans and Reconditions Extrusion and Filter Parts
The Pyrolysis Furnace EPO series from ECON GmbH excels in the environmentally friendly cleaning of extrusion and filter parts through vacuum-assisted pyrolysis. Designed for professionals in the plastics and polymer industries, the furnace efficiently removes thermoplastics and mixed plastics without the use of cleansing agents. The process involves a gradual temperature increase within a vacuum chamber, initiating pyrolysis to decompose polymer residues. This method ensures the integrity of dies, screen parts, and other sensitive components, which are cleaned residue-free, extending their operational life.
With a range of models from EPO 100 to EPO 1800, capacities cater to various scales of operation, with the largest model supporting up to 750 kg. ECON’s pyrolysis furnaces are equipped with a reliable, low-maintenance oil-lubricated vacuum pump and an activated carbon filter to handle exhaust gases, achieving emission-free operation. The inclusion of a collecting tray captures plastic residues, minimizing waste. The systems are designed for batch processing and can be manually operated with high efficiency, offering significant energy savings by eliminating the need for process water.
Ideal for plastics manufacturers, extrusion companies, and industrial cleaning services, the furnace’s integration into production lines is straightforward, serving as a critical step in maintenance and reconditioning of tools and components. Customization options and engineering support are available to meet specific plant requirements, ensuring seamless adaptation into existing workflows.
