Buy Edwards Gas Reactor Column (GRC) Gas Scrubber Parts Here. The Edwards Gas Reactor Column (GRC) gas scrubber uses a unique hot bed reactor technology to handle gas flows up to 60 slpm and destroy hazardous gases to below TLV (Threshold Limit Value) levels.  GRCs require no water supply and present no duct corrosion issues associated with the back-streaming of moisture.    Reactive process by-products are chemically converted to harmless inorganic salts that are locked into the cartridge allowing for safe disposal. The Edwards GRC is the ideal gas scrubber for Etch processes (metal etch, poly etch, oxide etch) given that the...
