HOx – Hot Oxidation System

The Hot Oxidation System (HOx) offers a significant advance in the performance of non-fuel oxidation technology. Targeted at CVD applications, the system ensures safe removal of pyrophoric gases to below flammable limits and the effective treatment of acidic by-products to prevent exhaust duct corrosion.
