At Wray Mechanical we have recently helped companies in the semi conductor industry with the design, manufacture and installation on Halar Coating Ducting. 

Halar ECTFE coatings and linings offer outstanding fire and corrosion protection to semiconductor applications. ECTFE is widely used as a coating or lining material for exhaust ducts, vessels and process equipment. ECTFE powder coatings enable exhaust duct systems to meet the FM4922 fire safety standard. ECTFE coated ductwork features exceptionally smooth surface to reduce the risk of contamination buildup and corrosion.
