Choosing the Right Material for Your Pyrolysis Chamber

The material used for a pyrolysis chamber is a crucial factor in determining its performance, safety, and how long it will last. The chamber must be able to handle extreme heat, resist corrosive elements, and remain structurally sound throughout the pyrolysis process. Opting for the wrong material can lead to frequent breakdowns, escalating repair expenses, and potential safety risks.
