Pyrolysis Cleaning

Pyrolysis Cleaning is a process used to remove contamination through heating the parts at controlled temperatures in a low oxygen atmosphere where the contamination is thermally and chemically decomposed to a dry residue. 

We use different shape and sizes of ovens to suit your part. Pyrolysis Cleaning is especially useful for the removal of modern speciality chemicals and high temperature resistant polymers. We can provide a high temperature in a low oxygen environment causing decomposition of even the highest thermal resistant polymers to ash without damaging the part. Precision Processing has an advantage over other pyrolysis processes as we can enhance the final clean of the equipment with our customised chemical cleaning processes.

Optimal Cleaning Solution

Bespoke Oven Cleaning

Precision Processing utilises two bespoke rate controlled ovens to effect the removal of a wide range of contaminants; from everyday paints and coatings, to modern chemical resistant polymers. The first oven Precision Processing utilises is a box oven able to accommodate parts up to 1.2 cubic metres. The second oven is a screw cleaning oven able to accommodate parts up to 4m in length

Fast Turnaround, Minimal Production Disruption

The use of Pyrolysis Cleaning is quicker and more efficient than typical workshop cleaning where manual processes are used. When Pyrolysis is supplemented with Precision Processing chemical processes as secondary cleaning parts can be returned to as-new condition and supplied to the customer ready for reinsertion on-line resulting in reduced down times.
