Delatech - Model 858/859 -Exhaust Gas Scrubber
The Delatech CDO 858/859 Exhaust Gas Scrubber has long been considered the standard for Advanced Chemical Vapor Deposition (CVD) Process gas abatement, and has been effectively used with all PECVD, LPCVD & MOCVD process gases. Delatech scrubbers are also widely used in Thin Film processes. This versatile gas scrubber utilizes a combination Thermal Oxidation Chamber and a Primary/Secondary Cooling Wet Scrubbing Chamber to effectively abate toxic, flammable and corrosive gases.
